Introduction to GasClam 2 _________________________________________________________
GasClam 2 is the world’s first in-situ continuous borehole gas monitor and logging instrument. It is an invaluable
tool for detecting and recording the concentration of a wide range of gases commonly required in monitoring
applications, including Methane (CH4), Carbon Dioxide (CO2), Oxygen (O2), Carbon Monoxide (CO), Hydrogen
Sulphide (H2S) and Volatile Organic Compounds (VOC).
In addition to the selected gases, the GasClam 2 also records temperature, barometric pressure and borehole
pressure. An optional borehole water level sensor can be fitted to measure fluctuations in the water table should
this data be required.
Samples can be taken at programmable intervals, providing an invaluable set of data. The GasClam 2’s default
setting is to take a sample every hour, giving it an operational life of approximately one month (using the
rechargeable battery packs supplied) which can be extended up to 3 months (using optional proprietary long-life
Lithium battery packs).
The GasClam 2 can operate as either a stand-alone logger or real-time monitor linked to data acquisition systems
(Telemetry) via an optional modem system or communication cable. Recorded data can be viewed using the
GasClam 2 software or exported for analysis to a spreadsheet.
The software is also used to setup the GasClam 2 for logging, including logging intervals, total number of samples,
power supply and venting options.
The GasClam 2 itself is built to the highest standards with the outer casing from stainless steel, is intrinsically safe
and is certified for use in explosive environments in hazardous zone 1 and conforms to International Protection
code IP68.
Ion Science Ltd recommends that users perform regular bump tests in conjunction with an annual service and
calibration, which is provided by the Ion Science service department or an Ion Science approved service centre.
In this manual a Warning identifies conditions and actions that pose a hazard to the User or the Unit.
WARNING: Before using the GasClam 2ou must read this and the software manual paying particular attention
to the sections covering optimisation of GasClam 2 performance and the effects of water.
WARNING: Do not connect or disconnect any cables in hazardous areas and do not use non-approved
equipment in hazardous areas such as laptops, notebooks and mobile phones.
WARNING: For reasons of intrinsic safety, batteries MUST NOT be changed within hazardous areas. Always
ensure you are in a safe area before carrying out any type of work on your GasClam 2.
WARNING: To maintain the Unit’s certification and intrinsic safety use ONLY GasClam 2 approved batteries,
external power supply junction boxes and spare parts.
