Direct Contact Spot Check® Thermometers


PTC®'s Spot-Check® Series of thermometers feature outstanding response and sensitivity. Their extremely low thermal mass and weight (1/2 ounce), along with a unique design, assure intimate thermal contact and a very rapid readout. Each thermometer is guaranteed to an accuracy of ± 2% of full scale range. PTC Metrology™ has NIST traceable and A2LA accredited certification services available.  

The instrument's bimetallic coil directly contacts the surface to be measured. In response to temperature, the sensor expands or contracts causing the dial itself to rotate.

The basic thermometer is designed for horizontal or slightly curved surfaces. A magnet and leaf spring is available to hold the thermometer against nonhorizontal, ferrous surfaces. Ancillary (maxmin) hands are furnished on certain models to mark the lowest and highest temperatures reached during the thermometer's exposure.


Available in Fahrenheit or Celsius Temperature Ranges
