New generation of robust ATEX approved gas detectors is lighter, smaller and ideal for first responders

Nov 09 2020

Leading gas detection and analysis instrumentation manufacturer QED Environmental Systems Ltd has launched the next generation popular Huberg Metrex gas detection instrument.

The new Metrex is ATEX rated and designed for pre-localisation, localisation and classification of leaks in natural gas distribution networks. 

A robust design and intuitive user interface ensures the new Metrex is ideal for first responder technicians who handle suspected gas leaks. Other key applications include bar hole gas measurement testing, purged gas lines and enclosed space monitoring. 

The new Metrex is significantly reduced in size compared to its predecessor and is also 50% lighter. 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 adverse weather conditions. 

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 a technician to carry calibration gas cylinders as the Metrex can perform a user calibration in air. 

QED have been designing and manufacturing gas analysers for over 25 years, their design and engineering expertise is fundamental to the proprietary sensing and detection capabilities built within the new Metrex.  It detects and measures gas ranges that span from 0  - 10 000 PPM.

A further significant improvement from the previous Metrex model is the feature to capture, and datalog surveyed data within the QED ProSoft natural gas compliance reporting software. This data transfer can be via the integrated Bluetooth data transfer or USB to PC.

QED’s Natural Gas Business Unit Manager, Peter Bloem commented, “We are excited to expand and improve the Huberg product range. The release of a vastly improved Huberg product like the Metrex in such a short space of time highlights QED’s engineering and production capabilities.  We are proud of what the team achieved.

The new Metrex offers existing product distribution partners a product to expand their business more significantly into the mains gas distribution networks.  We’re confident that the new METREX is an attractive product option for companies who are considering to diversify or upgrade their current product portfolio.”
