Dual Magnet Mount      |    Four Magnet Mount      |     Tab Mount      |     Spring-held      |    Cases These Four Magnet Mount Surface Thermometers are specifically designed to measure surface temperatures where the industrial environment requires the highest holding power. These thermometers are similar to the Dual Magnet Mount Surface Thermometers except they feature four magnets for increased holding power. They can be used on any horizontal surface or held magnetically to any magnetic surface. These instruments feature four high temperature alnico magnets that act as the thermometer's base and hold the instrument in place on magnetic surfaces. 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. Single Ancillary Hand This handy, resettable peak reading hand is available as an option for our Dual Magnet Mount, Four Magnet Mount, and Tab Mount thermometers. The ancillary hand is reset by simply turning the knob. A non impeding magnetic clutch holds the hand in place at either the maximum or minimum temperature reached during a cycle. Max-Min (Dual) Ancillary Hands The max-min hands are available on our Dual Magnet Mount, Four Magnet Mount, and Tab Mount thermometers. These hands 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 by a non impeding magnetic clutch. The hands are easily reset before each temperature cycle by using the reset knob and magnetic wand.
