Thermalarm III

Other features of the Thermalarm III are:

• Easier set-hand adjustment. The adjustable set-hands extend through the bottom of the instrument housing, so you can use your fingertips to adjust the high and low limits - no tools needed!
• Quicker response to temperature changes. Airflow through the opening at the bottom of the instrument case allows the instrument to sense air temperature change more rapidly.

The standard range of the Thermalarm III is from 20° F to 110° F.
