Introduction to GasClam
GasClam is the world‟s first in-situ borehole gas monitor, suitable for the detection of a wide range of gasses commonly
found in borehole monitoring, including Methane (CH4), Carbon Dioxide (CO2) and Oxygen (O2). In addition to this the
GasClam monitors temperature, barometric pressure and borehole pressure.
All of these readings can be taken at programmable intervals, providing an invaluable set of data to the user. The default
setting for the Gasclam is to take readings every hour, giving it approximately one months‟ operational life. Data is
downloaded either using a computer or via an optional modem and can be viewed within the GasClam software or
exported for analysis in Excel. Whilst connected to the software the settings of the GasClam unit can be altered,
including the frequency at which samples are taken and selecting venting options.
In addition to the sensors already mentioned, the GasClam can be upgraded with a Photo ionisation Detector (PID) for
detection of Volatile Organic Compounds (VOC‟s), a Carbon Monoxide (CO) sensor, Hydrogen Sulphide (H2S) sensor and
a water depth sensor should the data be required.
Ion Science Ltd recommends that regular customer bump tests take place in conjunction with an annual service and
calibration, which is performed by the Ion Science service department or an Ion Science approved service centre. Before
using the GasClam you must read this manual paying particular attention to the section on the effects of water on your
GasClam.
Note: Before removing the GasClam from the field it must be run once in atmosphere to purge any hazardous gasses.

The effects of water on your GasClam
GasClam is designed to overcome – as far as possible – the requirement to:
measure gas concentrations,
measure borehole and atmospheric pressure,
allow a venting pathway between the borehole and atmosphere.
To measure gas concentrations the gas must be dry and measurements of atmospheric pressure should not include the
pressure of overlying water. As the GasClam can be in a position liable to flooding from above (flooded headworks) and
below (high borehole water level) your help is required to optimise the performance of your GasClam by:
carrying out simple preventive and remedial maintenance
being aware of the limitations of data gathered under flood conditions.
1. Keeping your GasClam dry and clean in regular use
To dry the gas before measurement there is a moisture stripping filter in the bottom section of the GasClam. Over time
this will hydrate and its ability to remove moisture will decrease. If moisture is not successfully removed, concentration
readings will be affected. If the moisture stripping filter is completely saturated it can dissolve, and it will then be
pumped in to other sections of the GasClam resulting in catastrophic failure. This will always be avoided if the GasClam
is installed vertically and the filter is replaced after every 800 samples. However, it is recommended to renew the filter
whenever a visit is made to the GasClam to ensure optimal performance during data collection (see service and
calibration section).
To prevent water reaching the vent pathway the snorkel should always be attached to the vent hose barb. The top of
this should be supported so it is located at the top of the headworks to reduce the chance of water ingress. In situations
where the headworks is likely to be flooded the hose barb must be replaced by the vent blank. The supplied box spanner
can be used to remove the hose barb and the supplied vent Alan key used to replace with the vent blank and washer.
The GasClam should always have the snorkel attached to the vent hose barb (a). In situations where the
headworks is likely to flood the hose barb must be replaced by the vent blank and washer (b).

2. Effects of flooding on data and GasClam
When the unit is not sampling it has an ingress protection rating of IP-68 (submersible to 10 meters for 1 week).
However,
Immersion will effect data and
May require subsequent corrective action
These effects and requirements will differ whether immersed from above, i.e. flooded headworks, or from below, i.e. rise
in borehole water level, see table below:

Turning on the GasClam
The GasClam can be switched on and off using the remote. The remote connects to the
communication port on top of the GasClam.
To start the GasClam hold the button down for two seconds, the red LED will flash rapidly
indicating the GasClam has started and is currently going through the processes in a sampling
cycle, this equates to „sampling‟ mode.
After the sampling processes have finished the red LED flashes intermittently, this equates to
the „measuring‟ mode.
To stop the GasClam press the button for two seconds, when it has stopped the LED will stop flashing, this equates to
„sleeping‟ mode

The programme will run on the following platforms:
- Windows 98
- Windows 98 Second Edition
- Windows 2000 service pack 3
- Windows ME
- Windows Server 2003
- Windows XP service pack 2
- Windows Vista

The programme needs .Net Framework 2.0 (x86) installed to run properly. This version is included on the software CD,
alternatively it can be downloaded from the Microsoft website.
Running the installation software
Insert the installation CD or USB stick and copy the software folder on to the PC.
There are two installation options.
1) If you have an old version of DotNetFX, 2.0 (x86) then double click the „setup‟ icon to update the DotNetFX. (If
you already have this version and you try to upgrade an error will occur, ignore this and go to the next option)
2) If you already have this version of DotNetFX then double left click the „GasClamUnit‟ icon.
The guide will then take you through the installation process step by step.

Battery Change
Warning:
For reasons of intrinsic safety, batteries MUST NOT be changed within potentially flammable areas. Always ensure you are in a safe
area before carrying out any type of maintenance on your GasClam
Battery types that can be used:
For Intrinsic Safety and reduced risk of explosion you must only use Duracell 1.5 V LR20 Alkaline-Manganese
MN1300 batteries or a 2 x 1,2V LR20 Nickel-metal hydride Saft VH D 9500 rechargeable pack. Do not mix old and new
batteries within the same unit, change both batteries at the same time. Failure to do so will reduce battery
life of the new cell fitted.
The battery compartment is accessed by removing the 4 screws from the battery compartment lid, see diagram. To remove the
batteries tilt the GasClam until they fall out. Replace with the stipulated batteries positive terminal facing down. Take care when
replacing the cover to ensure the O-ring is not damaged by following the instructions below:
The integrity of this O-ring should be
checked every time the batteries are
replaced. This needs to be replaced if any
damage is noticed.
When tightening the cover alternate between
screws to ensure the cover sits on the
GasClam squarely. If this is not done the Oring may be damaged.
Push the battery compartment lid down square on the
GasClam
When the O-ring is resting on the battery compartment
push the lid down evenly on both sides to ensure it
travels down square. This will prevent damage to the
O-ring. When the O-ring is sitting in the compartment
loosely tighten the screws.
