9.2.2 Moisture Image Series Probe (cont.)
The MISP2 probe has an integral set of electronics that are permanently
attached (see Figure 78). Do not attempt to separate the probe from the
electronics.

The electronics module stores the probe calibration and reference data in
non-volatile memory; therefore, the user never needs to enter the data by
hand. The Moisture Image Series probes also feature continuous
compensation of their own analog circuitry to assure long-term electronic
stability.
The Moisture Image Series probes, when operated with an ATEX certified
PM880, are intrinsically safe and can be used in zone 0 areas.
The Moisture Image Series probes measure moisture content in a standard
range from –110°C to 20°C (–166°F to 68°F) dew/frost point temperature
and optionally from –110°C to 60°C (–166°F to 140°F). In addition, they
can be used to measure temperature in a range of –30°C to 70°C (–22°F to
158°F) and pressure 30-300/50-500/100-1000/300-3000/500-5000 psig.
