The A/NO2 transmitters are intended to be used for the continuous monitoring of exhaust in non-hazardous locations. Guidelines provided by NIOSH/OSHA 1987 p. 176 state that current levels are 1 ppm (1.8mg/m3) over a 15 minute period. Indoor concentrations above 0.5 ppm indicate the need for additional ventilation.
The A/NO2 uses a wide spectrum, long life electrochemical sensor to measure the amount of Nitrogen Dioxide in the environment. It is offered with a factory set range of 0 to 6 ppm, but can be field adjusted to a maximum range of 0 to 10 ppm.
The nitrogen dioxide transmitter provides a linear 4 to 20 mA or 2 to 10 VDC output. All A/NO2 sensors come with a two year factory warranty. An optional Relay/Buzzer and NEMA 4X rated enclosure may be available upon request.
