Toxic Gas detectors / Sensor Transmitters

Gas detector or sensor transmitter for online, continuous monitoring of all toxic gases as below. These transmitters offer industry standard analog output in current or voltage form, or digital signals like Modbus RTU with RS485 serial interface. Optionally, these are also equipped with potential free relays.

These can be mounted on wall, ceiling, columns, ducts or pipelines. These can be single gas or multi-gas detection transmitters, available with or without onboard display.

  • CO / carbon monoxide
  • CO2 / carbon dioxide
  • H2 / Hydrogen
  • C2H2/ Formaldehyde
  • C2H4/ Ethylene
  • F2 / Flourine
  • Cl2 / Chlorine
  • NO2 / nitrogen dioxide
  • NO / Nitrous oxide
  • SO2 / sulphur dioxide
  • H2S / Hydrogen sulphide
  • CS2 / carbon sulphide
  • HCN / hydrogen cyanide
