Model 2156 3% Carbon Dioxide Monitor

The Model 2156 is a non-dispersive infrared gas monitor designed as a fully functioning standalone unit for the continuous monitoring of carbon dioxide. The optical system is not affected by humidity. The diffusion gas cell is not affected by variations in relative humidity from 0 to 95%. It has a 0.56 inch high digital readout and two adjustable levels detect circuits with associated front panel indicators (yellow and red) and SPDT relay contacts.
