The METREX is 50% lighter in weight than the previous instrument. 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 rating adds to the robustness of the instrument when operating it in adverse weather conditions. QED’s design and engineering expertise can be seen in the proprietary sensing and detection capabilities built into the METREX. It detects and measures gas ranges that span from 0 - 1,000,000 PPM (part per million). A significant found in the Metrex is the feature to capture and data log surveyed data to the ProSoft by QED compliance reporting software. Data transfer can be via the ATEX integrated Bluetooth data transfer or USB to PC. The METREX has been classified ATEX certified (II 2 G Ex db ib IIB T4 Gb), to be safely operated in designated hazardous locations. Unlike traditional flame ionization detectors, the METREX does not require heavy fuel calibration gas cylinders to be carried by the operator while doing gas network surveys.
