ND500 Series Handheld Digital Thermometers

 

 

The ND500 series handheld thermometers are characterized with a thin, simple and lightweight structure with a large easy-to-read LCD digital display. It is applicable to the temperature measurement in all fields such as electric/electronic, food, chemical, metal machinery, air conditioning, by combining it with each detachable various kinds of temperature sensors, thermocouples and resistance thermometers.

 

Features

  • Indicator designed small and lightweight enough to carried in your pocket with a large easy-to-read LCD display
  • Auto-off function making battery life over 500 hours
  • Unique function including 20 data memory function, hold function and calculation (2-input type only)
  • Auto-range type with high resolution (0.1°C) at lower temperature (-199.9 to 199.9°C)
  • Thermocouple and resistance thermometer types are available.
