These simple to use, heavy duty, 50mm diameter bi-metal dial probe thermometers are reliable and accurate. Bi-metal thermometers use a long stem to transfer the heat to a coil just behind the dial. This expands or contracts according to the temperature the devices are exposed to. The dial of the bi-metal thermometer then displays the temperature.
The dial thermometers feature a 6.35 x 300mm pointed stainless steel stem.
Ideal for asphalt, blacktop, soil and other heavy duty applications
Each thermometer incorporates a clear acrylic face and a calibration adjustment nut at the rear of the dial
Available in three different temperature ranges – 0/250C, 0/120C and -20/60C.
