CTX300 Analogue Gas Transmitter

The CTX300 analog gas transmitter is a safe area gas detector with a 4-20 mA linear output for the detection of toxic gases (C2H4O, Cl2, ClO2, CO, COCl2, H2S, HCl, HCN, HF, NH3, NO, NO2, O3, PH3, SiH4, SO2), asphyxiating gases (Ar, CO2, He, O2), organic vapours (VOCs, alcohols, solvents) and refrigerant gases (CFC, HFC, HFO freons).

  • Detection of toxic gases, oxygen, and the main freons
  • 4-20 mA linear analog output, pre-calibrated and plug-in sensors
  • Very robust: insensitive to corrosive agents and high mechanical resistance
  • Optional backlit digital display for local indication of measurements
  • Certification for safe areas only, not ATEX classified
Additional information

The CTX 300 gas transmitter covers most industrial and service applications in safety areas, thanks to many interchangeable sensors. Very robust and small in size, it is simple to use with a conventional gas detection system or with a safety PLC thanks to its universal 4-20 mA linear output.

It is much popular in laboratories, research centres, the medical sector (clean rooms, MRI, cryogenic cells, etc.), the wine sector (wineries, breweries, cellars), the food industry (refrigeration systems), and industry (detection of toxic gases or solvents).

For calibration, periodic checks or gas tests of gas detectors, we offer a very wide range of calibration gases in single-use cylinders that comply with the ISO6142 standard.

Main detected gases*: Ammonia (NH3) - Arsine (AsH3) - Carbon dioxide (CO2) - Carbon monoxide (CO) - Chlorine (Cl2) - Chlorine dioxide (ClO2) - Ethanol (C2H6O) - Ethylene oxide (ETO) - Fluorine (F2) - Formaldehyde (C2HO) - Hydrogen (H2) - Hydrogen chloride (HCl) - Hydrogen cyanide (HCN) - Hydrogen fluoride (HF) - Hydrogen sulfide (H2S) - Nitric acid (HNO3) - Nitric oxide (N2O) - Nitrogen dioxide (NO2) - Oxygen (O2) - Ozone (O3) - Phosgene (COCl2) - Phosphine (PH3) - Silane (SiH4) - Styrene (C8H8) - Sulfur dioxide (SO2) - Toluene (C7H8)
