AC Infinity Digital VPD Thermometer Gun

Getting an accurate Vapour Pressure Deficit (VPD) reading requires knowing your actual canopy surface temperature, not just room air temps. The AC Infinity AC-TRV3 is the first dedicated laser thermal gun designed specifically to calculate both leaf VPD and air VPD, along with ambient temperature, leaf surface temperature, and relative humidity in real time.

Equipped with a 12-point infrared laser positioning array, the AC-TRV3 precisely targets leaf surfaces across various distances without giving false readings from grow light reflections. By measuring your crop's exact leaf temperature offset, you can program and calibrate your AC Infinity UIS™ smart controllers to trigger fans, heaters, and humidifiers based on true plant stress levels rather than simple ambient estimates.

What Makes It Stand Out

• True Leaf & Air VPD Calculations: Automatically computes both atmospheric and direct leaf VPD so you can fine-tune transpiration and nutrient uptake.

• 12-Point Laser Precision: Features a 12:1 distance-to-spot infrared targeting ring that highlights the exact measurement area for pinpoint surface reads.

• Controller Calibration: Provides accurate leaf-offset data needed to calibrate UIS smart controllers for automated climate management.

• Adjustable Emissivity (0.1 to 1.00): Allows you to adjust thermal radiation settings to match different leaf textures, plant species, or room surfaces.

• Historical Data Tracking: Automatically saves previous scan logs so you can monitor microclimate shifts across light-on and light-off cycles.

• Rapid Response Time: Delivers complete environmental metrics on a clear digital screen in under 500 milliseconds.

Real-World Applications

• UIS Controller Calibration: Finds the exact leaf temperature offset under LED, HPS, or CMH lighting to feed precise data into automated environment profiles.

• Canopy Hot-Spot Detection: Pinpoints shaded lower foliage versus top canopy hotspots to adjust airflow and light height.

• Greenhouse & Grow Room Auditing: Quickly spot-checks humidity and VPD across multiple tents or grow bays in seconds.
