The Extech 445814 is a professional-grade environmental monitor designed to provide total control over your indoor climate. Perfect for homeowners, lab technicians, and facility managers, this Humidity Alert Hygro-Thermometer goes beyond basic sensors by offering a specialized Dew Point calculation. By understanding the relationship between temperature and moisture, you can proactively manage environments to prevent wood rot, rust, or the dangerous onset of mold. The standout feature of the 445814 is its fully programmable alarm system. When humidity levels exceed or drop below your designated set points, the device triggers a loud audible buzzer and a flashing visual LED, ensuring you never miss a critical change in air quality. The large, high-contrast display shows temperature in either Celsius or Fahrenheit, while the Min/Max function keeps a historical record of environmental extremes. Built for long-term reliability and housed in a durable casing, the Extech 445814 is the ultimate diagnostic tool for maintaining optimal conditions in wine cellars, server rooms, greenhouses, and industrial storage facilities.

  • ADVANCED HUMIDITY ALERT SYSTEM: Take the guesswork out of climate control with programmable visual and audible alarms. Set your custom high or low humidity limits and receive instant alerts to prevent mold growth or protect sensitive equipment.
  • COMPREHENSIVE DEW POINT CALCULATION: Gain a deeper understanding of your environment by monitoring dew point alongside temperature and humidity. This essential metric helps you predict condensation and manage moisture levels with expert precision.
  • CRYSTAL CLEAR DUAL DISPLAY: View all critical data at once on the large, easy-to-read LCD screen. The simultaneous display of temperature and humidity ensures you have a complete snapshot of your indoor climate without ever pressing a button.
  • INTELLIGENT DATA TRACKING: Capture and recall the highest and lowest readings with the integrated Min/Max memory function. This allows you to monitor environmental fluctuations over time and identify problematic trends in your home or workspace.
  • VERSATILE MOUNTING OPTIONS: Adapt the monitor to any space using the built-in tilt stand for desktop use or the integrated wall mount. Whether in a laboratory, greenhouse, or basement, this rugged device provides reliable monitoring where it matters.
