SENTINEL-Plus/Pro Multi-Parameter Humidity Measurement Transmitter - OVERVIEW
by EdgeTech Instruments

The SENTINEL Humidity Measurement Transmitter is similar to the SENTRY Compressed Gas Alarm System in that they both incorporate a sensor control display module with the four-measurement parameter capability of the HP125 Series Humidity Probe (RH, Temperature, Pressure and Dew Point).  The notable difference between the two models is that the SENTINEL does not include the audible and visual alarm functionality. 

The table below is a summary of the features of both versions (SENTINEL-PLUS and SENTINEL-PRO):
