RKI CO-04C Carbon Monoxide (CO) Monitor with H₂ Compensation
- SKU:
- 73-0067
Description
The RKI CO-04C Carbon Monoxide (CO) Monitor with H₂ Compensation is a compact personal gas detector designed for continuous carbon monoxide monitoring in environments where hydrogen may be present. Its hydrogen-compensated CO sensor helps reduce interference from hydrogen, providing more reliable carbon monoxide readings in applications where standard CO sensors may be affected by H₂.
The CO-04C provides continuous monitoring of carbon monoxide from 0–2,000 ppm CO. A clear, easy-to-read display provides real-time gas readings, while audible, visual, and vibration alarms alert the user when carbon monoxide concentrations reach configured alarm levels.
Built for demanding industrial environments, the CO-04C features an IP67 impact-, dust-, and water-resistant enclosure, automatic alarm backlighting, datalogging capability, and a rotating alligator clip for convenient personal wear.
The instrument is powered by two AAA alkaline batteries and includes alkaline batteries and an alligator clip.
