Factory Cheap Hot Humidity Probe - HT-P103 ±1.5% high precision humidity sensor – HENGKO
Factory Cheap Hot Humidity Probe - HT-P103 ±1.5% high precision humidity sensor – HENGKO Detail:
HT-P103
The HT-P103 humidity probe utilizes a high-tech thin-film polymer capacitance (RHT-H) sensor. This sensor enables rapid response and high accuracy humidity and temperature measurements. The probe features a durable full metal body, waterproof stainless steel cap, internal temperature and relative humidity sensor, and built-in microchip that stores calibration data.
HT-P103 Digital Integration Air Temperature and Relative Humidity Sensor Probe with Cable for Enviromental RH/T measuring

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.

Waterproof stainless steel Cap
The HT-P103 is supplied with a stainless steel cap that allows for rapid response times for temperature and RH measurements. The appearance of the protective enclosure can be selected in a variety of specifications,and can be customized.

4-pin Connector
The HT-P103 relative humidity sensor probe uses a standard four-wire connector. This type of connector decreases the error validly, easier to wire.
Technical data humidity and temperature sensor
We adpots high precision RHT series capacitive digital sensor as the temperature and humidity measurement component. Please select the suitable model for your probe.
