The Handheld VPD Meter That Takes the Guesswork Out of Reading Your Plants Room-level VPD readings only tell you part of the story, what matters most is the VPD right at the leaf surface. The AC Infinity VPD Thermometer is a handheld infrared meter that captures leaf temperature, ambient temperature, humidity and VPD in a single point-and-read. It uses 12-point laser positioning to keep your reading accurate even at a distance, and lets you adjust emissivity to match different leaf surfaces for a properly calibrated result. It automatically saves your last 5 readings, so you can track how conditions are trending through a grow cycle, not just what they are right now. Captures leaf VPD, leaf temperature, ambient temperature and humidity in one reading Infrared sensor with 12-point laser positioning for accurate targeting Adjustable emissivity (0.1–1.00) to calibrate for different surfaces Saves your last 5 readings automatically Runs on 2x AAA batteries with a 20-second auto-shutoff Why measure leaf VPD, not just room VPD? Room sensors like our CloudCom Thermo-Hygrometer give you a great overview of your tent's climate, but leaf temperature can run a few degrees below or above ambient. Spot-checking with a handheld meter helps you catch stress before it shows up as a problem.
