  • Application areas

    Suitable for use in air environments, without the need for constant temperature stabilization in a constant temperature oil bath, it can be used as a working standard and can also be used as a high stability and high reliability comparison calibration device.

  • Product characteristics

    ●Filling the inner chamber with oil can reduce the impact of temperature changes on the resistance, and isolate the air to reduce the impact of humidity on the accuracy of resistance measurement, thus ensuring its high stability.
    ●Using EMF terminals to reduce the impact of thermoelectric potential.
