RKI Instruments

RKI Instruments

RKI Instruments is a California-based manufacturer specializing in gas detection equipment for industrial safety and environmental monitoring. The company designs and produces a comprehensive range of portable multi-gas monitors, fixed gas detector transmitters, gas sensor assemblies, and controller systems capable of detecting combustible gases, toxic gases, and oxygen deficiency. RKI Instruments is widely recognized in industries where worker safety and compliance with gas hazard regulations are critical.

The RKI product line includes single-gas and multi-gas detectors using electrochemical, catalytic bead (pellistor), infrared (IR), and photoionization detection (PID) technologies. Their instruments are used for confined space entry monitoring, area gas monitoring, and continuous fixed-point detection in facilities handling hazardous gases including methane (CH4), hydrogen sulfide (H2S), carbon monoxide (CO), and volatile organic compounds (VOCs).

Key Product Lines

• Portable multi-gas monitors — for confined space entry and personal gas exposure monitoring
• Fixed gas detector transmitters — wall-mount sensors for continuous area monitoring
• Gas sensor assemblies — replacement and OEM sensors including infrared and electrochemical types
• Calibration equipment — instruments and gas standards for field and laboratory calibration
• Controller systems — multi-channel panels for facility-wide gas detection networks

Industries Served

RKI Instruments equipment is used in oil and gas, petrochemical, wastewater treatment, utilities, mining, confined space safety, and industrial hygiene applications. Their detectors are commonly deployed in refineries, chemical plants, water treatment facilities, and any environment where toxic or combustible gas hazards are present.
