Wall Mounted Multipurpose Ammonia Gas Detectors with Alarms and Other Controls

Kernco Instruments Co., Inc. Is pleased to introduce its line of ammonia gas detectors with adjustable set points and alarm features designed to measure on a continuous monitoring basis ammonia gas. The sensor elements are explosion proof and are rated for Class I Division I, Group A-B-C-D hazardous atmospheres.

Three (3) models are available, Model 51A26 is a wall mounted stand alone ammonia gas detector with a range of 0-1000 ppm, Model 51A40 is a wall mounted unit that comes with a remote probe that comes with explosion proof housing that is reliable up to 1000 feet from controller. The third Model 51A45 is a portable model with same range of 0-1000 ppm.

Units feature an audible and visual alarm, meter read-out, failure and pilot signals, circuit test button and alarm set check button. Models are available for 115VAC operation, battery operation with a 3.6V NiCad rechargeable battery, and for remote 115VAC operations. Models measuring LP/gasoline vapor and combustible gas will measure PPM in a range of 0-1000 PPM. A 4-20mA or 0-1 VDC output option is available; a relay control option is also available.
