AC Infinity VPD Thermometer – Infrared Leaf Temperature & VPD Gun

AC Infinity VPD Thermometer – Measure the Leaf, Not the Room

A wall thermometer tells you how warm the room is. Your plant doesn't live in the room; it lives in its leaves, which under strong lights can be several degrees warmer or cooler than the air. VPD calculated from air temperature alone is an educated guess. Point this at the leaf and the guess becomes a measurement.

• Measures leaf temperature, ambient temperature, relative humidity, air VPD and leaf VPD
• 12-point laser ring shows exactly what you're measuring
• Saves previous readings so you can track change over time
• Use the numbers to calibrate your AC Infinity or other smart controller

Also handy for checking radiators near houseplants, cold windowsills, and whether your greenhouse staging is actually as warm as you think.

🌿 Rose's Pro-Tip: take readings at the top of the canopy, the middle and down low. Big differences tell you to improve air circulation before anything else.

Pairs well with: Cloudcom hygrometers, Controller AI+.

FAQs

Why measure leaf temperature?

Can I use it to calibrate my controller?
Yes. Compare its readings with your controller's and adjust.

Does it store readings?
Yes. It saves previous readings.
