Compact Temperature and Humidity Monitor

Compact Temperature and Humidity Monitor: Your Environment, Under Control

Keep a close eye on your environment's temperature and relative humidity with this compact, all-in-one monitoring device. Designed for clarity and ease of use, it's the perfect tool for homes, offices, greenhouses, labs, and more.

Clear, Comprehensive Display The large, crisp LCD screen provides at-a-glance readings of both local and remote* temperatures in your choice of Celsius (°C) or Fahrenheit (°F). It also prominently displays the current relative humidity. The monitor recalls minimum and maximum temperature readings for both sensors, allowing you to track fluctuations over time. A low-battery indicator ensures you're never caught off guard.

Customizable Alerts for Peace of Mind Set your own high and low alarms for both temperature and relative humidity. If conditions move outside your desired range, the monitor will alert you with both audible and visible signals, allowing you to take action quickly and protect sensitive items, plants, or environments.

Expand Your Monitoring Reach* Why limit yourself to one room? This monitor can be paired with up to two optional wireless remote sensors (sold separately). These sensors use a powerful 433 MHz RF signal to transmit data from up to 100 feet (30 meters) away in an open area. Place them in critical locations like greenhouses, wine cellars, server rooms, or cold storage, and view their readings directly on the main display unit.

Ready to Use, Easy to Place The monitor comes complete with two AAA batteries. Its versatile design allows for either desktop or wall-mounted placement, fitting seamlessly into any space.
