Surface Temperature Bimetal Dial Thermometers
2″ diameter dual magnet surface temperature thermometers are designed to measure temperatures of many different surfaces. The base of the unit is placed on the surface to be measured. The sensing element then directly contacts the surface; expansion or contraction of the bimetal element results in dial readout.
