Dwyer TRI-100-25E is a Tridicator Gauge that measures ambient temperature from -40 to 250°F (-40 to 120°C) and process temperature from 80 to 290°F (30 to 140°C). It has an accuracy of ±3-2-3% for pressure and ±1 scale division for temperature. The housing is made of drawn steel with a black finish, and it is compatible with gases and liquids. The wetted material includes brass connection and phosphor bronze Bourdon tube. The gauge has a pressure limit of the full scale range and can be connected using a 1/2" male NPT back or bottom, or a 1/4" male NPT back connection. It has dimensions of 3" (76 mm).
