What is the measuring range of the H Series temperature sensor?

Standard range is -200°C to 800°C with ±0.5°C accuracy; ±0.1°C accuracy is available on request. The three-wire probe connection keeps readings stable in electrically noisy plants.

How long does the battery last?

The transmitter is designed for more than 10 years of battery life at a one-hour reporting interval — actual life varies with network conditions, temperature, and reporting frequency. The transmitter is fully battery-powered; only the short probe cable to the transmitter is needed.

How does the sensor report data?

It transmits over 4G or NB-IoT using MQTT to Hitelecom Cloud, a customer cloud, or a private deployment, and pushes alerts when temperature crosses configured thresholds.

Can the sensor be customized for our application?

Yes. Accuracy, probe length and cable, reporting interval and enclosure can be customized under Hitelecom's OEM/ODM program. Contact sales with your working conditions.
