RKI 03 Series

Personal Single Gas Monitors

RKI's 03 Series single gas clip-on personal monitors include four models: CO-03, (CO), HS-03 (H2S), OX-03 (O2), GP-03 (Combustible Gas). 3,000 hours operation on 2 AA batteries or 30–35 (Ni-MH or alkaline) for GP-03. Affordable; small; field-replaceable sensors.

RKI's 03 Series single gas clip-on personal monitors comes in four versions including the GP-03 for combustible hydrocarbons/LEL (0–100%, 1% increments), CO-03 for carbon monoxide/CO (0–500 ppm, 1 ppm), HS-03 for hydrogen sulfide/H2S (0–100 ppm, 0.5 ppm), and the OX-03 for oxygen deficiency/O2 (0 – 40%vol., 0.1% vol.).

Features include peak hold, STEL, and TWA; audible, visual, and vibration alarms; an automatic backlight. Data logs 5–300 hours with an adjustable interval. Replacement sensors are inexpensive and field replaceable. Operates for 3,000 hours on alkaline (GP-03 operates 30 or 35 hours on Ni-MH or alkaline respectively) with a low battery alarm.

The 03 Series is intrinsically safe (ATEX & CSA). pocket sized (2.1" W by 2.6" H by 0.9" D), weighs only 2.8 oz, includes a replaceable rubber boot, is impact/dust/water resistant (IP-67), and comes with a two (H2S & CO) or three (LEL & O2) year warranty.
