The AC Infinity VPD Thermometer is a handheld environmental monitor designed to help growers make more informed decisions about their grow room conditions. By measuring leaf surface temperature, air temperature, relative humidity, and automatically calculating Vapour Pressure Deficit (VPD), it provides the data needed to optimise plant growth throughout every stage of cultivation. Unlike standard thermometers, this device measures the temperature of the leaf itself using infrared technology, allowing for far more accurate VPD calculations and helping growers maintain ideal transpiration rates.
Why VPD Matters
Vapour Pressure Deficit (VPD) plays a vital role in how efficiently plants absorb water and nutrients. If VPD is too high or too low, plants can become stressed, slowing growth and reducing yields. The AC Infinity VPD Thermometer removes the need for manual calculations by displaying live VPD readings instantly, allowing you to quickly assess whether your grow room is operating within the ideal environmental range. Whether you’re growing seedlings, maintaining vigorous vegetative growth, or pushing plants through flowering, accurate VPD monitoring helps create healthier plants and more consistent harvests
Fast, Accurate Readings
Simply point the infrared sensor at a leaf to instantly measure its surface temperature while the built-in sensors simultaneously record the surrounding air temperature and humidity. The large digital display clearly presents all environmental readings, making it easy to monitor conditions in seconds. Compact, lightweight and easy to use, it’s an invaluable tool for checking multiple plants throughout your grow room without disturbing your environment.

* Compact handheld design for quick spot checks throughout your grow room
* Ideal for grow tents, grow rooms, propagation areas and greenhouses
* Suitable for every stage of plant growth
Why Choose the AC Infinity VPD Thermometer?
Environmental control doesn’t stop at measuring room temperature. Because leaf temperature often differs from air temperature, accurately measuring VPD requires both values. The AC Infinity VPD Thermometer provides growers with professional-level environmental monitoring in a simple handheld device, making it easier to fine-tune growing conditions and maximise plant performance.
Our Recommendation
If you’re serious about improving plant health and achieving consistent results, the AC Infinity VPD Thermometer is an excellent addition to your grow room. Pair it with an AC Infinity Controller 69+ or Controller AI+ to monitor your environment continuously while using this handheld meter to verify leaf temperatures and fine-tune your VPD throughout every stage of growth.
