  • Type: Contact
  • Display Type: Analogue
  • Temperature Range: -56.7-21.1°F (-70-70°C)
  • Accuracy: +/- 2% of Full Scale
  • Time Constant (Depending on Range): 0.06 to 1 min.
  • Dual magnet surface thermometer is specifically designed to be used on horizontal or ferrous non-horizontal surfaces
  • Two alnico magnets act as the thermometer's base and hold it in place on ferrous surfaces
  • Bimetallic sensor is a specially processed alloy that is preconditioned and pretested for permanent calibration and maximum stability
  • Sensor is located in a draft shield and is in virtual thermal contact with the surface to be measured, giving it a relatively quick response time
  • Reaches sensing equilibrium (stability) within three minutes
  • Applications include hot plates, griddles, die-cast dies, foundry core boxes, annealing ovens, weld preheats, motors, generators, engines, bearings, boilers, and tanks
