GD-09-6M Six-in-One Multi Gas Detector with built-in Pump

213,300.00 including GST @18%

Six-in-one Pumping Multi Gas detector for 6 gases: Oxygen (O2), Carbon Di Oxide (CO2), Carbon Monoxide (CO), Hydrogen Sulfide (H2S), Nitrogen Di Oxide (NO2) and Explosive Gases (EX). Also features PM2.5/PM10 detection module, 4G module and GPS.




The Metravi GD-09-6M Pumping Multi Gas Detector is intelligently designed with advanced, integrated circuit technology, standard intelligent technical level design and proprietary digital-analogue hybrid communication technology.

It detects 6 gases: Oxygen (O2), Carbon Di Oxide (CO2), Carbon Monoxide (CO), Hydrogen Sulfide (H2S), Nitrogen Di Oxide (NO2) and Explosive Gases (EX).
It integrates electro-chemistry, catalysis and various detection principles such as semiconductors, thermal conductivity and optics to provide users with a reliable, accurate and safe gas detection solution.
The GD-09-6M also features PM2.5/PM10 detection module, 4G module and GPS.

The detector adopts a built-in pump-suction sampling method and the sensitive element adopts a high-quality gas sensor. It has good sensitivity and excellent repeatability, is easy lo use and helps to maintain the safety needs of industrial sites.

For high-reliability, the shell is made of high-strength engineering plastics and composite, non-slip rubber, which has high strength, solid hand feeling, and is waterproof. dust-proof and explosion-proof.

It is widely used in petroleum, chemical, environmental protection, smelting, refineries, manufacturing biochemical medicines, agriculture, scientific research, universities and other industries and fields.


*Note : The Metravi GD-09-6M can be customised for selected 6 gases from a given list (ref. catalogue) – the cost for the same will depend on the combination and features selected. The standard pre-designed device comes with CO, O2, CO2, NO2, H2S and EX detection.
