The Extech 445814 Humidity Alert Hygro-Thermometer is a versatile device that provides precise and convenient monitoring of humidity, temperature, and dew point. This hygro-thermometer features a programmable audible and visual alarm that alerts you when the humidity exceeds your desired limit.

The Extech 445814 is equipped with a large LCD display that simultaneously shows the current temperature, humidity, and dew point readings. This allows for easy and convenient monitoring of multiple parameters at a glance.

This meter accurately measures humidity in the range of 10% to 99% and temperature in the range of 14 to 140 degrees Fahrenheit (-10 to 60 degrees Celsius). With a basic accuracy of ±4% RH and ±1.8 degrees Fahrenheit (±1 degree Celsius), you can rely on the displayed readings for accurate humidity and temperature monitoring.

The Extech 445814 also features a rear calibration pot for humidity and temperature. This allows for adjustments and fine-tuning to ensure optimal accuracy and alignment with standard reference points.

The maximum/minimum with reset functions store and recall the highest and lowest recorded readings for humidity, temperature, and dew point. This feature is useful for monitoring fluctuations over time and identifying critical points or trends in the recorded values.
