INSTALLATION
2.6.2 Pura OEM & PRM Connection
The Pura OEM and PRM have been assembled and packaged within a Class 100 cleanroom environment. To maintain this level of cleanliness the packaging should only be
opened within the same, or cleaner, environment.
Michell Instruments recommends the use of Swagelok
®
retained gasket assemblies,
containing silver plated, stainless steel ¼” VCR gaskets, when connecting the Pura into
a gas line. The distance between the inlet and outlet gas connection ports is set at a
pitch of 120mm (4.7”).
1. Install the sealing gasket onto the VCR connections on either the
Pura or the connecting gas lines. Ensure that the Pura is offered
into the gas line with reference to the gas fl ow direction and the
inlet port, as indicated on the Pura body.
Inlet
Outlet
Figure 11
Inlet/Outlet Identifi cation
NOTE: In order to identify the Inlet and Outlet without
dismantling the instrument it is necessary to look through the
Inlet/Outlet holes. Looking through the INLET hole a shiny end
can be seen, looking through the OUTLET hole an elongated
shape can be seen.
2. Tighten the female nut fi rmly, fi nger tight.
3. Hold the Pura transmitter stationary with a spanner/wrench and
tighten the gas line nut 1/8 of a turn using a second spanner/
wrench.
4. Repeat this operation on the remaining gas connection port.
CAUTION: Over-tightening the nuts can cause irrecoverable
damage to the seals and seatings.

INSTALLATION
2.6.3 Pura SEN - Direct Pipeline Connection
The transmitter may be directly mounted into a pipe or duct
.
CAUTION: Do not mount the transmitter too close to the
bottom of a bend where any condensate in the pipeline might
collect and saturate the probe.
The pipe or duct will require a ½” VCR male process connection thread to match
the transmitter body thread. Fixing dimensions are shown in
Figure 12.
For circular
pipework, to ensure the integrity of a gas tight seal, a mounting fl ange will be required
on the pipework in order to provide a fl at surface to seal against.
Procedure
The following procedure must be carried out by competent
personnel.
1. Ensure that the red protective cover has been removed from the
tip of the transmitter.
WARNING: Under no circumstances should the fi lter guard be
handled with the fi ngers.
2. After fi rst checking that the pipeline has a wide enough bore to
accept the transmitter’s process connection, screw the transmitter
into the pipe. Tighten enough to obtain a gas tight seal. (Torque
will depend upon the pipeline material.)
Michell Instruments recommends the use of Swagelok® retained gasket assemblies,
containing silver plated, stainless steel ½” VCR gaskets, when connecting the Pura into
a gas line.
NOTE: Do not overtighten or the thread on the pipework may be stripped.

OPERATION
3 OPERATION
Operation is very simple assuming the following installation techniques are adhered to:
Sampling Hints
Be Sure the Sample is Representative of the Gas Under Test:
The sample point should be as close to the critical measurement point as possible. Also,
never sample from the bottom of a pipe as entrained liquids may be drawn into the
sensing element.
Figure 14
Installation Location
Minimize Dead Space in Sample Lines:
Dead space causes moisture entrapment points, increased system response times, and
measurement errors as a result of the trapped moisture being released into the passing
sample gas and causing an increase in partial vapor pressure.
Deadspace
Figure 15
Indication of Dead Space
Remove Any Particulate Matter or Oil from the Gas Sample:
Particulate matter at high velocity can damage the sensing element and similarly, at
low velocity, they may ‘blind’ the sensing element and reduce its response speed. If
particulate, such as degraded desiccant, pipe scale or rust is present in the sample gas,
use an in-line fi lter, as a minimum level of protection. For more demanding applications
Michell Instruments offers a range of sampling systems (for more information contact
www.michell.com).
Use High Quality Sample Tube and Fittings:
Michell Instruments recommends that, wherever possible, stainless steel tubing and
fi ttings should be used. This is particularly important at low dew points since other
materials have hygroscopic characteristics and adsorb moisture on the tube walls,
slowing down response and, in extreme circumstances, giving false readings. For
temporary applications, or where stainless steel tubing is not practical, use high quality
thick walled PTFE tubing.
Position Transmitter away from Heat Source:
It is recommended, as good instrumentation practice, that the transmitter is placed
away from any heat source to avoid adsorption/desorption.

Appendix C Quality, Recycling & Warranty Information
C.1 Pressure Equipment Directive (PED) 97/23/EC
The above Directive has been implemented in United Kingdom Law by the Pressure Equipment
Regulations 1999.
The Regulations require that all pressure equipment and assemblies within the scope of the Pressure
Equipment Directive must be safe when placed on the market or put into service.
Michell Instruments’ products have been assessed and, as referenced against the Classifi cation Charts
detailed in Annex II of the Directive, do not fall into the requirements for CE marking compliance
with the Pressure Equipment Directive.
Article 3, paragraph 3 states that any product containing a pressurized fl uid that does not qualify for
compliance should, nevertheless, be constructed with Sound Engineering Practice (SEP).
Michell Instruments attests here that its products have been designed, manufactured & tested to
assure safe operation, and in accordance with Sound Engineering Practices.
C.2 Recycling Policy
Michell Instruments is concerned with the protection of the environment. It is our commitment to
reduce and eliminate from our operations, wherever possible, the use of substances which may be
harmful to the environment. Similarly, we are increasingly using recyclable and/or recycled material
in our business and products wherever it is practical to do so.
To protect natural resources and to promote material reuse, please separate batteries from other
types of waste and recycle responsibly. If batteries are not properly disposed of, these substances
can cause harm to human health and the environment.
The product that you have purchased may contain recyclable and/or recycled parts and we will be
happy to provide you with information on these components if required. For further information
please see the following sections.
C.3 WEEE Compliance
Directive 2012/19/EU 4 July 2012 on Waste Electronic and Electrical Equipment (WEEE)
The Waste Electronic and Electrical Equipment (WEEE) Directive places rules upon European
manufacturers of electrical and electronic equipment. The directives’ aim is to reduce the impact
that electronic devices have on the environment.
Michell Instruments is in full compliance with the WEEE Directive and is registered with an approved
recycler (Registration No. WEE/JB0235YW) and treats the requirement of the directive and the
protection of the environment with the utmost importance. All Michell Instruments’ products are
appropriately marked indicating their requirement for recycling.
It may be required to return certain instruments for treatment at the end of their working life.

C.4 RoHS2 Compliance
Directive 2011/65/EU of the European Parliament and of the Council of 8 June 2011
The Restriction of Hazardous Substances (RoHS) Directive places rules upon European manufacturers
of electrical and electronic equipment. The directives’ aim is to reduce the impact that electronic
devices have on the environment.
According to the EC Directive 2002/95/EC, Michell Instruments’ products qualify as Category 9,
Control and Monitoring Equipment. Under the 2002/95/EC Directive, Category 9 products are exempt
from compliance with the Directive.
However, the careful design of all Michell Instruments’ products takes into consideration the
requirements of the Directive and, wherever possible, compliance is achieved. All future products
will be developed entirely using compliant materials. Furthermore, Michell Instruments is taking
active steps to remove non-compliant materials and components from existing products wherever
these may occur. Presently, none of the non-compliant materials are known to occur in Michell
Instruments’ products.
The new Directive 2011/65/EU (RoHS2) entered into force on 21 July 2011 and required all Member
States to transpose the provisions into their respective national laws by 2 January 2013.
Under the provisions of the RoHS2 EU Directive 2011/65/EU (Article 3, [24]) defi nes ‘Control and
Monitoring Equipment’ specifi cally as ‘monitoring and control instruments designed exclusively for
industrial or professional use’.
RoHS2 EU Directive 2011/65/EU states the closing date for compliance of any Control and Monitoring
Equipment product sold into the EU market place as 22nd July 2017.
However, the careful design policy of all Michell Instruments’ products continues to attain compliance
in the shortest practical timescales and strives to ensure that less than 0.1% of total mass per
product, of all non-compliant materials, appear within them. Michell Instruments continues to
monitor suppliers and material sources to ensure that compliance of goods provided is maintained.

C.6 REACH Compliance
Regulation (EC) No. 1907/2006
Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH)
Michell Instruments is a manufacturer of moisture measurement and gas analysis instrumentation
and is a ‘downstream’ user of chemicals, as described by the EU Council Directive 76/769/EEC. The
products we supply are not raw chemical products (goods).
Under normal and reasonably foreseeable circumstances of application, the goods supplied to you
shall not contain or release any prohibited chemicals. No listed SVHC (Substances of Very High
Concern) appear within products manufactured by Michell Instruments. Therefore the 0.1% mass
per product, or total usage of 1 tonne/year, will never be exceeded. For these reasons we are neither
required by obligation for registration nor for the creation of material safety data sheets (MSDS) for
our products.
Our continued review of the SVHC Candidate List and
latest additions is to ensure we remain
compliant.
Michell Instruments maintains a hazardous material register in which MSDS data sheets are collated,
and we will check that our suppliers will comply to REACH requirements for all materials and
substances we use in the processes of our manufacturing.
In the unlikely event that any chemicals of concern appear in our products in quantities greater than
0.1% of total mass per product we will immediately inform you by correspondence according to the
REACH Article 33 requirements. Our current appraisal is, however, that we do not expect or foresee
such an incidence.

C.7 Calibration Facilities
Michell Instruments’ calibration facilities are among the most sophisticated in the world and have
been recognized for their excellence.
Traceability to the National Physical Laboratory (NPL) UK is achieved through our UKAS Accreditation
(Number 0179). This covers dew point over the range -90 to +90°C (-130 to +194°F) and also
Relative Humidity.
Dew-point calibrations are also traceable to the National Institute for Standards & Technology (NIST)
USA over the range -75 to +20°C (-103 to +68°F).
NOTE: Standard traceable calibration certifi cates for instruments and sensors are not
issued under our UKAS accreditation. UKAS certifi cates are usually to special order and
are clearly identifi ed.
