The SPECTRUM ON-LINE instrument is an inexpensive, high performance, microprocessor-based continuous air monitor. This instrument incorporates simple operation, an easy-to-read digital display, along with a highly specific electrochemical sensor in a small durable cast aluminum housing. This unique gas detector is designed for use in a variety of applications including R & D facilities, university laboratories, boiler rooms, loading docks, refrigeration compressor rooms, and in other light industrial applications where detection and alarm of oxygen levels or toxic gas is required.
The use of a gas sampler generally improves monitoring performance for all gases. It is particularly recommended for Cl2, HCl, AsH3, and it is required for monitoring HF and O3.
Instruments are readily available for monitoring CO, H2S, Cl2, O3, SO2, NH3, NO2, NO, HCl, H2, HF, AsH3, SiH4 and O2. Please contact ENMET for more information on a specific gas not listed on this brochure.
