RKI is pleased to announce the release of our infrared line of detector heads. IR heads are now available with our Direct Connect Sensors, the S Series transmitter, and the M2 stand alone transmitter with digital display.

Calibration Kits New calibration kits are also now available which include a new calibration cup designed for the IR sensors, part # 81-1103RK. Below is a complete chart of available calibration kits for each IR sensor.

New Datasheets Available Attached you will find updated datasheets for the Direct Connect Sensors, S Series, and M2 transmitters that include the details for each IR sensor. These data sheets are also available on RKI's web site. Also attached is the price sheet for the available IR detector heads, which include part numbers and pricing. Currently you can get an IR sensor in the following versions:

LEL Methane 65-2619RK-CH4 (M2 Stand Alone)
65-2390RK-CH4 (S Series Transmitter)
61-0190RK-CH4 (Direct Connect Sensors)
LEL Hydrocarbons (Propane calibration)
65-2619RK-HC (M2 Stand Alone)
65-2390RK-HC (S Series Transmitter)
61-0190RK-CH4 (Direct Connect Sensors)
Carbon Dioxide (0-5% volume)
65-2391RK-03 (S Series Transmitter)

The carbon dioxide IR sensor for the M2 and Direct Connect sensors is currently under development and will also soon be available with the same 0 – 5% volume range.

IR Advantages Infrared sensors have a variety of advantages over other sensor technologies. For example IR sensors are more resistant to sensor drift or sensor poisoning. They can sustain continuous exposure to gas samples and the life expectancy is much longer than traditional catalytic sensors. They are especially useful in applications where catalytic LEL sensors are poisoned by silicone, or where no oxygen is present (inert environments).
