Our company ordered testing of an updated version of GFM 2.0. Testing was carried out by the Energy Institute of the Colorado State University (CSU) – one of the most respected centers for testing instrumentation for indication and measurement in the field of combustible gases. Four categories of testing were performed: Lower Detection (LDL), Quantification Accuracy, Gas Composition Response, and Practical Use. As a result, the GFM 2.0 appears to be well made and suitable for field use. The ability to use any Android device as a control/display is useful/flexible. The small, relatively lightweight form factor and ability to use it with or without the backpack attachment provides operators with options to suit their preferences. The extract from the report is available for download on our website for registered users (you can request the full version at firstname.lastname@example.org).
