Digital Panel Mount Thermometer

The Value Brand Digital Panel Mount Thermometer 13E397 uses an NTC thermistor sensor to display temperatures from -58 to 158°F (-50 to 70°C). It is suited for technicians and hobbyists who need a compact, solar-powered readout with AAA battery backup for continuous operation in control panels or equipment enclosures.

Surface Mount Design and Build

The unit mounts on a flat surface and houses its electronics in a black ABS case measuring 1 inch high by 4 inches wide. A stainless steel 304 sensor probe 1.25 inches long and 1/4 inch in diameter connects via a 2 ft wire, allowing the display to stay accessible while the sensor reaches the measurement point.

Accuracy Limits and Sensor Constraints

Accuracy is rated at ±1.8°F between -4 and 86°F, widening to ±3.6°F outside that span. The 1 second response time suits steady-state monitoring but not rapid transients, and the fixed 2 ft sensor lead may limit placement in larger cabinets without extension.

Highlights

  • Wide -58 °F to 158 °F range covers diverse environments
  • ±1.8 °F accuracy from -4 °F to 86 °F ensures reliable readings
  • Solar power with AAA battery back-up keeps display running
  • Surface-mount design with 2 ft stainless-steel sensor wire simplifies installation
  • Compact 1 in × 4 in black ABS case fits tight panels
