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 (CH
4
), Carbon Dioxide (CO
2
) and Oxygen (O
2
). 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 (H
2
S) 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.
