Digital Thermohygrometer

Feature

■ SK-90TRH is one of the pioneering electronic thermohygrometers released by Sato. Its high repeatability and responsiveness, automatic temperature compensation processed in a microcomputer contribute to condensation- and humidity-resistant property.

■ High quality resistive humidity sensor HSK-III enables long-term measurement in high humidity ambient

■ One-chip microcomputer for precise calculation

■ Sensor filter for dusty environment

A sensor filter of a dedicated material is included in the kit to cover the sensor section without worsening the accuracy in dusty environment.

■ High repeatability and responsiveness

SK-80TRH has a humidity sensor achieved to minimize the effect of hysteresis as little as ±1% with high responsiveness. Ideal for a wide range of humidity measurement.

■ Displays wet bulb temperature. Hold function equipped.

SK-90TRH displays wet bulb temperature in addition to temperature and humidity, calculated from the two values.

Hold switch enables the measured figures frozen temporarily to help you read them.
