## Overview

The AC Infinity VPD Thermometer is a cutting-edge handheld environmental monitor designed for professional growers. It precisely measures leaf and air vapor pressure deficit (VPD), ambient and leaf temperature, and relative humidity using advanced infrared technology with 12-point laser targeting. This device enables accurate calibration of smart grow controllers, tracks historical climate data, and features a waterproof, portable design powered by included AAA batteries. Ideal for greenhouses, grow tents, and terrariums, it empowers millennial growers to optimize plant health and maximize yields with data-driven precision.

## Description

Product Description 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. Applications This wholly unique instant environmental monitor measures VPD, temperature, and humidity levels to promote successful plant growth. Fit for use in horticultural settings like gardens, grow tents, grow rooms, and greenhouses to support ideal growing conditions. This meter can also aid in calibrating VPD-enabled smart controllers by helping to measure leaf offset for more precise leaf VPD readings.

Review: Rubbish - Humidity takes forever to adjust (like a whole night) and it's 10% off... Absolute rubbish

### ⭐⭐⭐⭐⭐ Worth the money
*by A***W on 20 December 2025*

I was surprised these guns weren’t dearer because some guns that only read temp are more expensive. It seems well made too I’d definitely say they’re worth the money!! If you grow using vpd as a guide one of these guns is a must it takes all the guesswork out and the plants love the temp and humidity I’ve set it at
