Magnetic Surface Thermometer

Dual Magnet Mount Surface Thermometers are specifically designed to measure surface temperatures.

Made in the USA of quality materials, these thermometers can be used on any horizontal surface or held on any magnetic surface. These instruments feature two high temperature alnico magnets that act as the thermometers base and hold the instrument in place. The bimetallic sensor is located in a draft shield and is in virtual thermal contact with the surface to be measured. This gives the instrument a relatively quick response time. The thermometer reaches sensing equilibrium (stability) within three minutes. Single or max-min ancillary hands are available for this instrument as an option.

Designed for applications such as: hot plates; griddles; die-cast dies; foundry core boxes; annealing ovens; weld preheats; motors, generators, and engines; bearings; boilers, tanks ect.

PTC Metrology is accredited by A2LA to ISO/IEC 17025, ANSI/NCSL Z540-1-01 for NIST traceable certifications. Our calibration lab has several choices for surface thermometer calibrations from basic NIST traceable certification to customer selected logged critical temperature points which include as received and as returned data; a statement of uncertainty; laboratory conditions and information on the primary standards. 

Max-Min Dual Ancillary Hands

The max-min hands are available on Dual Magnet Mount, Four Magnet Mount, and Tab Mount thermometers. These hand have been designed to provide the user an easy way to obtain both maximum and minimum temperatures for a given cycle. The ancillary hands are held in place be a non impeding magnetic clutch. The hands are easily reset before each temperature cycle by using the reset knob and magnetic wand.

Single Ancillary Hand

This handy, resettable peak reading hand is available as an option for Dual Magnet Mount, Four Magnet Mount, and Tab thermometers. The ancillary hand is reset by simply turning the reset knob. A non impeding magnetic clutch holds the hand in place at either the maximum or minimum temperature reached during a cycle.
