The METREX is significantly reduced in its size and up to 50% lighter in weight versus competition. It features ten hour battery life and an easy to read and navigate LCD display. Gas measurements are displayed on screen to the user and easy to understand. The IP65 certified ingress rating adds to the robustness of the instrument when operating it in severe weather conditions. It detects and measures gas ranges that span from 0 - 10 000 PPM (part per million). Metrex captures and datalogs surveyed data to the ProSoft by QED mains gas compliance reporting software. This data transfer can be via the ATEX integrated Bluetooth data transfer or USB to PC. ATEX certified (II 2 G Ex db ib IIB T4 Gb) the new METREX has been classified to be safely operated in designated hazardous locations. Unlike traditional flame ionisation detectors, the new METREX does not require, for example, heavy fuel calibration gas cylinders to needs to be carried by the operator while doing gas network surveys.
