RKI Instruments, ----S2 Series, Diffusion Sensor / Transmitter Assembly

From RKI Instruments,

S2 series gas sensor / transmitters. Highly reliable and very cost effective for the detection of common gas hazards. The S2 series are available for LEL, H2 Specific (LEL, and ppm), Oxygen, H2S, CO, and for a variety of toxic gases. The transmitters for LEL, H2 Specific, Oxygen, H2S, CO2, and Carbon Monoxide are explosion-proof with flame arrestors, and approved for use in hazardous areas (Class l, Groups B, C, D). An optional non-explosion proof version is available for oxygen, H2S, CO, and CO2 in non-hazardous atmospheres. LEL sensors are available using catalytic bead and infrared technologies.

Toxic sensors are electrochemical type plug-in sensors, providing high specificity, fast response, and long life. Plug-in design allows quick replacement in the field with no tools required. Toxic sensors are designed for use in Class I, Div. 2 hazardous locations. Sensors available for Cl2, NH3, SO2, PH3, AsH3, and HCN. S2 transmitters can be used either indoors or outdoors. Flame arrestors for the explosion-proof versions utilize a patented coating which make them water repellent. Splash guards are also available for use in very wet environments.

All RKI Instruments S2 transmitters are designed to interface with RKI controllers, or with PLC/DCS systems.
