Enquire This Product

Flammable Gas Detector DA100 is a “SMART” gas detector designed to detect and monitor flammable gases in the air in the range of 0 to 100 % LEL using Catalyst Cell technology.

  • The DA100 is an intelligent electronic device that applies Rezontech’s.
  • unique algorithm and has a user interface and comprehensive fault.
  • diagnosis capabilities.
  • The transmeter design also features Rezontech’s advanced technology.
  • suitable for Catalyst Cells. The gas-sensitive sensor assembly is stainless.
  • steel and the transmeter housing is designed to protect against.
  • corrosion and other effects by coating aluminum with epoxy and with an internal pressure-resistant structure.
Highlights
  • Explosion proof construction for internal pressure can be installed in high risk gas leakage areas.
  • Continuous detection of combustible gases from low up to high concentrations by applying a high sensitivity sensor.
  • 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 to 20 mA and digital communication signal RS-485, Modbus Compatible.
  • Convenient structure for calibration and maintenance.
