TOXIC AND OXYGEN GAS DETECTOR

차량정보 표
Model No. TOXIC & OXYGEN GAS DETECTOR Model : QM-9000D
Category GAS DETECTOR, TOXIC AND OXYGEN GAS DETECTOR

Description

Description
  • TRANSMITTER TYPE (4~20mA), RS-485 MODBUS (OPTION)
  • FND LOCAL DIGITAL DISPLAY
  • MODEL : QM-9000D
Features
  • Premium gas detector for real-time monitoring of toxic gas and oxygen concentration in areas with potential toxic gas presence.
  • Flickering or lightning user selection feature.
  • Gas detector with on-site display and backlit LCD for continuous identification of toxic gas concentration in low-light conditions.
  • High-intensity LED Warning Flash Lamp (H.HH).
  • Gas detector with various functions such as zero and concentration calibration, temperature compensation, and record verification of the final calibration date via magnetic key or computer monitoring system.
  • 4~20mA, Dry contact (1st, 2nd, 3rd), 24V DC, Fault output function (Option).
  • IP66 and Internal pressure explosion-proof certified by IECEx, ATEX, and KGS.
  • Galvanically isolated RS-485 network: a highly robust field-bus network capable of limiting the propagation of external noise, such as lightning, to a localized area.
  • When expanding the detection unit, it automatically connects to the nearest communication line and integrates with the rellated computer monitoring system, allowing for automatic expansion and contraction, resulting in cost savings forinstallation and maintenance management.
