The GENie-NH3 is a portable, hand-held, accurate gas calibration instrument for calibrating ammonia gas sensors. It uses a small, cylindrical sealed glass ampule that when broken and placed in the device, emits a small quantity of gas that is user adjustable allowing for the calibration of almost any ammonia detector on the market. The instrument requires a base unit (which provides a micro-processor based user interface and control system), an Ammonia (NH3) generating module and Ammonia gas source. The LCD display is capable of showing the menu structure in English, French, German and Spanish. It is powered by 4 heavy duty AA alkaline batteries that provide approximately 6 hours of continuous operation (at 0.5 LPM). It comes with 12 gas vials that do not have a shelf life and are non-hazardous to transport. Each vial will provide up to 8 hours of continuous calibration gas before the empty vial is discarded. The delivery hose comes standard with the unit o# erring a 1.5 m long x 4.76 mm OD (5 ft long x 3/16 in OD) Teflon lined hose for delivering the gas to the sensor or calibration adaptor. It also comes with a nylon carrying case for convenience and protection. The front of the carrying case is clear plastic, allowing the unit to be operated while within the case.

The GENie-NH3 should be sent back to the factory after 100 hours of use or annually for calibration to ensure proper operation of the ultraviolet light source, the flow meter and to replace the internal charcoal filter to promote optimum performance.
