GAS DETECTOR

차량정보 표
Model No. TOXIC & OXYGEN GAS DETECTOR QM-5700D / (VOCs) / Toxic
Category GAS DETECTOR

Description

Features

- Diffusion gas detector equipped with toxic and oxygen-sensitive sensors.

- Gas detector with a dedicated gas detection principle, providing excellent selectivity and

   minimal interference from other gases by reacting specifically to the target gas.

- IP66 and Internal pressure explosion-proof certified by IECEx, ATEX, and KGS.

- Calibration and program settings: ZERO point, Span (Automatic Setting with no volume required except for 4–20mA).

- Calibration and maintenance by a single person.

- Minimization of the impact of noise, temperature, and humidity.

- Connection of the analog standard output (4–20mA) signal to DCS & PLC monitoring systems.

- Install the system in hazardous areas at industrial sites to measure combustible gases in real-time, providing a 

  4–20mA standard output for connection to control devices, alarm devices, and monitoring systems.
