Overview

LEL monitor
GP-03

Individuals need personal protection in hazardous areas at all times without adding extra bulky equipment, and the GP-03 can provide that kind of protection at an affordable price. The GP-03 is a personal single gas monitor designed for protection from exposure to combustible hydrocarbons.

The GP-03 operates for 35 hours on alkaline and 30 hours on rechargeable Ni-MH. The GP-03 model has 2 preset alarms that are user adjustable. It is also equipped with visual, audible, and vibration alarms as standard. The replacement sensor is inexpensive, easily field replaceable, and is interchangeable with other popular RKI instruments like the GX-2009 and GX-2012. The LEL sensor has a life expectancy of over 2 years.

The GP-03 is impact, dust, and water resistant with an IP-67 rating. The GP-03 is safe for use in hazardous locations, classified as intrinsically safe ATEX/IECEx and by CSA to U.S. and Canadian standards for Class I, Division 1, Groups A, B, C, and D atmospheres.
