  • Product Description

    The TM-5012B handheld two channel platinum resistance meter can accurately display the characteristic error parameters of standard platinum resistance thermometers or industrial platinum resistance thermometers after graduation by inputting them into memory through the instrument keyboard. Eliminating the hassle of users checking tables or using computers to calculate temperature values, achieving accuracy, speed, simplicity, and convenience.

  • Application areas

    Suitable for direct reading measurement and precise/fast temperature value display of standard platinum resistance thermometers and industrial platinum resistance thermometers, it is an essential secondary electrical measuring instrument for on-site calibration, measurement, and temperature measurement rooms

  • Product characteristics

    ●Channel 1 and Channel 2 are independent of each other and can be measured simultaneously, with dual channel measurement values (Ω/℃) displayed simultaneously.
    ●Resistance (Ω)/Temperature (℃)/Direct reading digital display.
    ●Support the storage of characteristic parameters for multiple standard platinum resistance thermometers/industrial platinum resistance thermometers.
    ●Measuring constant current commutation with minimal temperature drift greatly reduces the impact of environmental temperature changes during measurement, ensuring measurement accuracy.
    ●Equipped with a built-in lithium battery for power supply, it is ultra small and portable, easy to operate, economical and practical. It can also be powered through an adapter when not equipped with a lithium battery.
