EXTECH RH101 IR termo-higrometer

The EXTECH RH101 is a versatile IR thermo-hygrometer that combines non-contact infrared temperature measurement with ambient temperature and humidity monitoring. Its strongest capability is measuring IR temperature from -50 to 500°C with an 8:1 distance-to-spot ratio, making it ideal for quick surface temperature checks without direct contact.

Advantages

This meter provides a complete environmental measurement solution in one handheld device. It calculates dew point and wet bulb temperature automatically, helping you assess condensation risk and heat stress conditions. The backlit LCD ensures readability in dim environments, while data hold and min/max functions capture critical readings. Auto power off conserves battery life.
