A highly innovative laser thermometer gun designed to instantly measure leaf VPD, air VPD, ambient temperature, leaf temperature, and relative humidity to precisely calculate true VPD data. Using these environmental figures, you can calibrate your smart controller so it can accurately detect the climate and trigger your grow devices at precise times. This is the first of its kind to track the VPD (vapor pressure deficit) of your plants and the surrounding atmosphere, allowing you to make pinpoint adjustments for optimal nutrient uptake. It can also review past readings so you can closely monitor changes in your climate. The sensor utilizes infrared technology to capture measurements using 12-point laser positioning, ensuring an accurate reading over a wide range of distances. The programming can even adjust for a surface’s emissivity, ensuring greater accuracy by accounting for efficiency in emitting thermal radiation, which varies from surface to surface.
