AI Technical Summary
Existing clamp meters do not integrate a humidity probe, resulting in large errors in temperature and humidity detection. Furthermore, operating two devices increases detection time and safety risks.
The temperature and humidity probe is integrated into the clamp meter and placed outside the meter housing. It uses detachable electrical connection components, including an aviation plug and a metal hose, to ensure that the probe is close to the measurement area.
It improves the accuracy of temperature and humidity detection, reduces equipment switching time, lowers operational complexity and safety risks, and enables synchronous data acquisition.
