Active Air Digital Hygro-Thermometer

Active Air Digital Hygro-Thermometer is a digital hygro-thermometer for monitoring temperature and humidity, giving you a clear, daily view of your room’s climate. As a temperature and humidity monitor, it keeps the numbers you care about visible in one place so you can stay aware of changing conditions without adding complexity to your setup.

The jumbo LCD display is designed to be easy to read at a glance, showing a current temperature and humidity reading so you can check conditions quickly. Along with live readings, max and min memory helps you spot the highest and lowest points that occurred between check-ins. That simple history view is useful for noticing swings that can happen when you’re not watching, especially in spaces where conditions change with lights, ventilation, or seasonal shifts.

This unit also includes an auto-switch display that cycles between the main indoor relative humidity and temperature display and an additional outdoor temperature reading via a remote temperature sensor. In practical terms, that gives you a simple way to keep an eye on two temperature zones while still tracking humidity from the main unit. The sensor design includes a stainless steel sensor tip, built for reliable sensing in the area you want to monitor.

For everyday convenience, the display supports °C and °F conversion, so you can view readings in the format you prefer. It also offers versatile placement options with a wall-mount keyhole and fold-away stand, making it easy to keep the screen visible on a wall, shelf, or bench. The result is a compact climate display that stays readable and useful in busy grow areas, propagation spaces, or any indoor gardening environment where consistent monitoring matters.

Active Air Digital Hygro-Thermometer is a good fit for growers who want straightforward climate visibility: a digital hygro-thermometer with a jumbo LCD display, max and min memory, an auto-switch display, and a remote temperature sensor for keeping track of more than one temperature zone while continuously monitoring humidity.
