Description

Specifications

SKU: ZADETECTOR G90 4-1Multi-gas detector

Detection method	Natural diffusion type
Sensor life	2 years (catalytic combustion type and electrochemical type)
Ambient temperature	-10°C to +55°C
Relative humidity	＜93%

This G90 4-1 Multi-Gas Detector is a portable detection instrument that can be equipped with single or multiple gas sensors to detect various gases depending on the sensor types. The product can continuously monitor the concentration of gases in the ambient air, effectively ensuring the safety of workers and preventing damage to production equipment. This product is compact, easy to operate, convenient to carry and has good vibration resistance. lt uses high-resolution dot matrix LCD display technology, providing a more intuitive and clear display.

It's suitable for use in areas with explosive gas mixtures of zone 1 and 2 with categories ll A, ll B, ll C, and temperature groups T1 to T4: dust-tight enclosures are used for zone 21 and 22.
