Relative Humidity Probe

Hanna humidity probes utilize a high-tech thin-film polymer capacitance (TFPC) sensor. The HI70602 features a durable ABS body, perforated cap, internal temperature sensor, and built-in microchip that stores calibration data. Built-in Microchip A built-in microchip allows for calibration data to be stored in the sensor as opposed to the meter. If the probe is connected to another hygrometer, the microchip transfers the stored calibration data and eliminates the need to recalibrate the instrument. Internal Temperature Sensor The integrated temperature sensor of the HI70602 is crucial for accurate humidity measurements. Since the temperature of air can drastically change the amount of moisture that it is able to hold, obtaining a fast, stable temperature measurement allows for a highly accurate relative humidity reading. ABS Body Acrylonitrile butadiene styrene (ABS) is a strong, chemically resistant thermoplastic polymer. The electrical properties of ABS ensure that it is not affected by changes in temperature and atmospheric humidity. Perforated Cap The HI70602 is supplied with a perforated cap that allows for rapid response times for temperature and RH measurements. It is recommended for use in relatively clean environments that do not have dust or powder. DIN Connector The HI70602 uses a DIN connector. This type of connector is generally proprietary to the meters they are supplied with and may not be interchangeable.
