Solid State NH3 & Refrigerant Monitors 2050/2060

Sierra Monitor’s NH3 2050 and Refrigerant 2060 monitors are continuous duty, low cost stationary monitors for detection of high levels of Ammonia (NH3) and halocarbon refrigerant gases.

The 2050/2060 monitors are based on solid state (semiconductor)technology, a simple and robust method of detection capable of detecting low points-per-million (ppm) levels of gases.

The 2050/2060 monitors are primarily used in and around freezers, refrigerators, and compressor rooms to warn of leaks and dangerous levels of these gases. Housed in a polystyrene enclosure, these monitors are made to withstand and provide stable detection in these applications. The alarm on a 2050/2060 monitor is activated when the concentration of gas exceeds the factory preset (and user adjustable) limit. Alarm signals can be relayed to a gas alarm control system.
