## Overview

The AC Infinity VPD Thermometer is a cutting-edge handheld environmental monitor designed for precision plant care. It uniquely measures leaf and air vapor pressure deficit (VPD), ambient and leaf temperature, plus relative humidity using advanced infrared technology with 12-point laser targeting. Ideal for growers aiming to optimize nutrient uptake and calibrate smart controllers, it also stores historical data to track environmental changes. Waterproof and battery-powered, it’s built tough for professional horticultural settings like grow tents and greenhouses.

## 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
Review: Absolut empfehlenswert! - Bin absolut zufrieden. Handhabung isr kinderleicht: Batterien an, einschalten, drauf halten. Viel komplizierter ist es nicht, zumindest die aktuellen Werte abzulesen. Scheint präzise zu sein, zumindest die Umgebungsbedingungen stimmen mit meinen Spider Farmer Sensoren überein und die Blatttemperatur entspricht dem erwarteten Wert. Fühlt sich gut an, mit diesem Gerät noch mehr Kontrolle über den Grow zu haben. Für Perfektionisten wie mich absolut empfehlenswert!
