Real-Time Monitoring of Temperature, Humidity, and Dew Point with Visual & Audible Alerts
The AZ 87791 Dew Point Thermohygrometer is a reliable, high-precision device designed for continuous monitoring of temperature, relative humidity (RH), and dew point temperature. With a large, easy-to-read LCD display, programmable danger zone alerts, and flexible mounting options (desktop or wall), this unit is ideal for use in laboratories, storage areas, basements, wine cellars, and HVAC-sensitive environments.
Equipped with a capacitance-type RH sensor, the 87791 delivers fast and accurate readings. It features audible and visual alerts (buzzer + red LED) when the monitored environment enters preset risk zones, helping users quickly identify vapor condensation risk or climate control failure. The dew point calculation allows predictive monitoring of condensation before it occurs.
