    Individuals need personal protection in hazardous areas at all times without adding extra bulky equipment, and the 03 Series can provide that kind of protection at an affordable price.  The GP-03, OX-03, CO-03, and HS-03 models are personal single gas monitors designed for protection from exposure to combustible hydrocarbons, oxygen deficiency, hydrogen sulfide, or carbon monoxide.

    The O₂, CO, and H₂S versions can be operated continuously for at least 3,000 hours on (2) AAA size alkaline batteries.  The GP-03 operates for 35 hours on alkaline and 30 hours on rechargeable Ni-MH.  The 03 models have 2 preset alarms that are user adjustable.  Each version is also equipped with visual, audible, and vibration alarms as standard.

    The replacement sensors are inexpensive, easily field replaceable, and are interchangeable with other popular RKI instruments like the GX-2009, GX-2012, and GasWatch 2.  Sensors for LEL and O₂ have a life expectancy of over 2 years.  Sensors for H₂S and CO have a life expectancy of over 3 years.

    Each 03 Series monitor is impact, dust, and water resistant with an IP-67 rating.  03 Series instruments are safe for use in hazardous locations, classified as intrinsically safe ATEX/IECEx and by CSA approval to U.S. and Canadian standards for Class I, Division I, Groups A, B, C, and D atmospheres.
