DMR20-1-TMP Digital Thermometer

The DRM20-1-TMP is a digital thermometer with thermistor probe that accurately measures air temperatures from -40 to +221°F (-40 to +105°C). You can choose between °C or °F readings via a rear pc-board jumper. The thermistor probe features 18 in leads to allow for remote installation.
There are two display brightness levels provided to ensure optimal readability under various ambient lighting environments. Visual indications alert you to over or under temperature conditions and an open or shorted thermistor.

The thermometer features a round polycarbonate housing that provides excellent protection against moisture, dust, shock and vibration. It also features a built-in resettable fuse to guarantee long-term reliability.
