Greystone HRC3NT20P 3% c/w 24 Vac/dc supply, jumper selectable outputs, 20,000 ohm thermistor, 0-10K slide pot. The HRC Series uses an accurate thermoset polymer based capacitance humidity sensor with digital linearization temperature circuitry in low profile enclosure to monitor room RH levels. The first number after "HRC" is the accuracy percent; 2, 3 or 5% (Use the Build Your Part Number graphic below to identify the needed part number).
