The Model 200M is a complete instrument for the measurement of atmospheric dew or frost point, ambient temperature, percent relative humidity and other psychrometric variables. It employs the very reliable optical chilled mirror sensing technique which provides a primary measurement of dew point, and is traceable to NIST. The Model 200M is ideally suited for installations requiring continuous, automatic, and unattended measurement of humidity over a very wide range.
Automatic Balance Control (ABC) cycle corrects the light reducing effects of mirror contaminants and allows for continuous monitoring and virtually maintenance-free operation. This is the first and only chilled mirror technology that truly reduces the need for cleaning by the incorporation of self-diagnostics, which indicates to the user, locally via an LED light source and remotely via logic level TTL signal, when and if maintenance is required.
