Flammable Gas Detector DB100

Enquire This Product

Flammable Gas Detector DB100 is a “SMART” gas detector designed to detect and monitor toxic (CO, H2S, HCI, etc.), oxygen, and VOC gases in the air by applying electrochemical, galvanic, and PID sensors.

  • Flammable Gas Detector DB100 is an intelligent electronic device that applies Rezontech’s unique algorithm. It has a user interface and a comprehensive fault diagnosis function. In addition, the transmitter design is characterized by applying Rezontech’s advanced technology suitable for electrochemical, galvanic, and PID sensors.
  • When assembling the sensor that detects gas, stainless steel was applied. The transmitter housing is coated with epoxy on aluminum to prevent corrosion and designed with a pressure resistant explosion proof structure.
Highlights
  • Explosion proof construction for internal pressure can be installed in high-risk gas leakage areas
  • Continuous detection of oxygen and toxic gases by applying excellent sensors
  • Self diagnosis function and various algorithms secure stability and reliability
  • Measured concentrations and operation status are indicated on the LCD or OLED display
  • 2 gas alarms, 1 fault displayed and relay contact output
  • Remote calibration and program settings are available using the Magnet bar
  • Multiple output options, analog 4-20 mA and digital communication signal RS-485, Modbus Compatible
  • Convenient structure for calibration and maintenance
