## Overview

The AC Infinity VPD Thermometer is a cutting-edge handheld environmental monitor designed specifically for growers. It uniquely measures leaf and air vapor pressure deficit (VPD), ambient and leaf temperature, plus relative humidity using precision infrared technology with 12-point laser targeting. This device automatically saves historical data for trend tracking and helps calibrate smart controllers to optimize plant growth conditions in greenhouses, grow tents, and terrariums. Compact and battery-powered, it delivers professional-grade accuracy with a 0.1°F resolution, making it an essential tool for millennial growers seeking data-driven cultivation success.

## Description

Product DescriptionA 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. Ambient readings update steadily, ensuring a more accurate reflection of your environment over time. 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.ApplicationsThis 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: Humidity takes forever to adjust (like a whole night) and it's 10% off... Absolute rubbish
Review: 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

Moin Ein quasi must have wenn man spezielle Pflanzen 🌱 züchtet. Die Werde sind sehr genau, habe sie mit teuren Geräten verglichen. Kein Unterschied. Vor allem wenn man die Blatttemperatur und die kPA wissen möchte. Unverzichtbar und hat mir schon oft geholfen meine Werte im Zelt anzupassen. Einziges kleines Manko, das Display könnte hochwertiger sein, bei 900 ppfd volle Pulle aufs Gerät, ist das Display nicht abzulesen. Ist halt AC Infinity, die bauen nur sehr hochwertige und nützliche Dinge. Ungewöhntlich für US Produkte, aber die spielen in einer eigenen Liga.
