AUTO SAMPLING TYPE GAS DETECTOR

차량정보 표
Model No. AUTO SAMPLING TYPE FLAMMABLE, TOXIC, OXYGEN DETECTOR QM-9500D
Category GAS DETECTOR, AUTO SAMPLING TYPE GAS DETECTOR

Description

Description
  • 4~20mA (Transmitter), RS-485 Modbus (OPTION)
  • FND LOCAL DIGITAL DISPLAY
  • MODEL: QM-9500D
Features
  • Continuous detection of ambient gases in areas with potential gas leaks.
  • Quick detection of gas leaks with a high-performance pump(Diaphragm pump) built-in.
  • The first of its kind in Korea, equipped with an automatic humidity & water discharge solenoid valve, which dries moisture caused by water or temperature changes when external air is sucked in, and automatically discharges the sucked water.
  • Field-Bus Network of RS-485 Modbus (Isolated) Serial communication.
  • High intensity LED Warning Flash Lamp.
  • Remote calibration and program setting using a 1:1 communication method via magnetic key or computer monitoring system without opening the cover.
  • Internal pressure explosion-proof.
