Important hints
To exclude any risk to persons, it is necessary to connect the sample
gas outlet (TOXIC GAS) of the instrument with the flue gas hose to
the flue gas duct.
Please confirm after successful connection the security message at
the instrument with <OK>.
Please connect flue gas hose to flue
gas duct before starting!
Please confirm (OK) before
starting, that the sample gas outlet
(TOXIC GAS) has been connected
through the flue gas hose to the
flue gas duct!

3. 2-stage Peltier cooler
Flue gas with a temperature above the dew point is sucked spiral via
a long gas path thru a surface coated metal body with good thermal
conductivity. The gas radiates its heat to this metal body
A Peltier
element (semiconductor cooling element) flown by a continuous
current is thermally connected with this body and with a second
metal body with cooling ribs and ventilation slots. The current thru
the Peltier element creates a heat transfer from hot to cold, drains
the heat of the metal body flown by gas and transfers it to the outer
cooling body. This heat is transferred thru ventilation to the
surrounding air.
The condensation issued by the heat loss of the gas drops in a
receptacle and is pumped out by a permanent working hose pump.
The sucking capacity of the gas conveying pump avoids a sufficient
dwell time of the gas with the condensate, so that wash out reactions
(NO
2+H2
O > H2NO3) do not take place. At the cooler outlet the gas
has a temperature of ca. 5 °C with a relative saturation of nearly 100
% relative humidity (corresponds to a water steam content < 7 g/ m
3
).

4. Heated sampling system
By using a heated sampling system (option) is possible to measure
water-soluble substances (NO
2
and SO2) without washout. A built-in
hot gas filter protects the instrument especially for long-term
measurements from fouling. The maximum exhaust gas temperature
when using the heated sampling system is 500 ° C.
- Do not bend the tube
- Heated tube has to be cooled out after the
measurement
- Heated tube may not be folded too tight
(use the whole under case)
- Do not put the heated tube in water
- Clean or replace PTFE filter regularly

5. Converter (option)
The NO2 / NO Converter converts catalytically the NO2 content of
the sample gas into NO. For this purpose, the sample gas is passed
through a converter cartridge from stainless steel having a catalyst
filling. This conversion allows an indirect measurement of NO2
(switch function key <F1> at the control unit to toggle between NO
and NOx measurement).
Replace reactor cartridge
:
Replace the reactor cartridge if the conversion rate from NO2 => NO
falls below the required value. Changing the reactor cartridge is
possible without tools in a very short time. We recommend turning off
the instrument and letting cool down for approximately 1 hour before
changing the cartridge. This minimizes the hazard of burning. There
is also the possibility of changing cartridges in a heated instrument,
but the converter cartridge has a temperature of about 200 ° C.
The converter cartridge is hot! Touching may cause
severe burns! Wear suitable protective gloves and
protect the converter cartridge against access!

How to change the reactor cartridge:
- Stop sample gas flow (deactivate NOx measurement).
- Before opening the reactor fastener make sure that no toxic or
dangerous gases or components are provided within the gas way.
(Purge the tubes with inert gas or air).
- Turn the reactor fastener counter anticlockwise up to the end of the
thread.
- Pull out the fastener with the reactor cartridge carefully.
- Let the cartridge cool down if needed.
- Pull the reactor cartridge out carefully from the reactor fastener
(wear protective gloves).
- Replace new reactor cartridge to the reactor fastener.
- Push the cartridge carefully to the reactor opening and turn the
reactor fastener clockwise up to the end of the thread.

6. Power supply
The basic module of the ecom-J2KN
pro
TECH is delivered with
internal loading unit. The connection of the power plug is needed to
operate the instrument.
The control module of ecom-J2KN
pro
TECH is powered by 3 nickelmetal-hydride accumulators (type AA). In case of need, the
accumulators can be recharged by docking the control module to the
basic module.
Used accumulators can be returned to us or brought
to recycling stations of public waste disposal compa-
nies respectively accumulators selling stores!
Never use batteries, to operate the control
module of the ecom-J2KN
pro
TECH!

7. Radio communication basic / control module
Thanks to the detachable control
module the basic module can be
monitored wireless. The basic module
can be unlocked as follows:
1. Press to unlock.
2. Tip control module forwards
3. Release control module from basic
module
The information exchange between
control and basic module is performed
via radio transmission (868 MHz) with
coverage of approx. 70 m (by free
sight). The quality of the radio
transmission is documented by a bar
indication in the main menu of the
instrument (long bar = good radio
communication).
By interruption of the radio
communication, an error message is
displayed. By persisting disturbances of
the radio communication, a cable
(option) can take over the transfer
(connection betwen socket DATA on
control unit and socket DATA on basic
module).
If the basic module is switched off and
the control module not, so the display
will show an error message inviting to
fix the control module in its docking
station (helps also not to forget the
control module). Observe this order, quit
with <ESC> and finally switch off the
control module.

8. Data record
The multi-media card enables the storage of both punctual
measurements and data logger records.
The values of punctual measurements are written in a text file
(J2KDV.txt). Those of data logger records in a csv file (J2KDL-xx.csv
/ xx = records numbered consecutively).
Both file types have the same structure and can be imported
respectively opened in Excel. See chapter „Technical Data“ for data
format information. The files can be transferred on the PC using a
card reader. The following conditions must be fulfilled for using a
multimedia card:
- ecom-J2KN
pro
TECH
- min. card volume 32 MB - max.32 GB (UHC)
- card formatted on 16 bit FAT or FAT32
- SD cards from SanDisk recommended
- PC with card reader
Insert the multi-media card as shown.
Take care that the card does not stand
out and hooks on.
Never pull out cards during data record
and damaging of the data carrier possible!

If measurements are carried out first the basic module has to be
turned on (switch below the info display). Select the sub-menu "Gas
analysis" with the cursor keys and confirm with <OK>. The
instrument starts with a warm-up phase (max. 30 min.). After the
sensors are at operating temperature, a 15-minute stabilization
phase follows followed by a 3-minute calibration with fresh air.
Simultaneously, the message appears asking if you want to use the
data processing. If you want to assign the sampled data to a specific
plant, so press <F1> (<F4> = no: measurement will be performed
without assignment).
