Custom Gas Analyzer Systems

RealTech Controls can manufacture cost-effective, custom gas analyzer systems to meet customer requirements. The gas transmitters are for remote mounting, with options for explosion-proof housings to be connected to intrinsically safe signal conditioners.

Single or multi-parameter systems can be provided, with optional wireless transmitter technology and user-interfaces. Bluetooth connectivity to any smart device, and data-logging are standard.

Standard gas transmitter systems are available for LEL (general purpose or H2 specific), Hydrogen (H2), Oxygen (O2), Hydrogen Sulfide (H2S), Carbon Monoxide (CO), Methane (CH4), Hydrocarbons (HC), and Carbon Dioxide (CO2).

Systems for toxic gases are also available for Ammonia (NH3), Arsine (AsH3), Chlorine (Cl2), Chlorine Dioxide (ClO2), Hydrogen Cyanide (HCN), Phosphine (PH3), and Sulfur Dioxide (SO2).
