Page 5 - DESCRIPTION
Page 5 DESCRIPTION Housed in a wall-mount, water-tight plastic enclosure, the DPS3301 Series is a powerful temperature monitor/indicator. It accepts a single Thermocouple, RTD or Thermistor sensor input and then displays the temperature in either degrees C or F. In addition, it also monitors a numbe...
