Active Air® Hygro-Thermometer with Jumbo LCD Display, Digital

Active Air Digital Hygro-Thermometer with Jumbo LCD Display

Keep tabs on your grow room conditions from across the room. The jumbo LCD shows temperature and humidity at a glance, with simultaneous max/min memory and an auto-switching display between the outdoor probe temperature and indoor humidity.

Why growers mount one in every room

• Jumbo LCD display: easy to read from a distance while you work.
• Max/min memory: see the overnight highs and lows without watching the screen.
• 3-meter remote sensor: a corrosion-resistant stainless steel probe measures outdoor or remote-zone temperature.
• Flexible placement: wall-mount keyhole or fold-away stand for desks, benches, and shelves.
• Switchable units: flip between Celsius and Fahrenheit with one button.

Measuring ranges

• Indoor temperature: -10° to 50°C (14° to 122°F), resolution 0.1°, accuracy ±1°.
• Outdoor temperature: -50° to 70°C (-58° to 158°F), resolution 0.1°, accuracy ±1°.
• Humidity: 25% to 98% RH, resolution 1%, accuracy ±3% between 50–80% RH and ±5% outside that range.

How to use

Stand it up or hang it, run the sensor cable to the zone you want to track, and check readings daily to keep temperature and humidity dialed in for your plants.
