VPD Thermometer, Handheld Environmental Monitor, Captures Leaf VPD and Temperature

The AC Infinity VPD Thermometer (Model AC-TRV3) is a state-of-the-art digital thermal gun that sets new standards in environmental monitoring for indoor and greenhouse growers. Designed with precision and efficiency in mind, it is the first device of its kind that accurately measures air and leaf VPD (Vapor Pressure Deficit), alongside ambient temperature, leaf temperature, and relative humidity. This functionality allows for optimal control over the growing environment, enabling growers to maximize nutrient uptake and support plant health.

Innovative Features for Precision and Control

1. Comprehensive VPD and Temperature Monitoring

• Dual VPD Measurement: By measuring both air and leaf VPD, this thermometer provides an in-depth understanding of the vapor pressure dynamics that influence plant transpiration. Monitoring VPD helps growers fine-tune humidity and temperature for ideal plant water intake, reducing risks of under- or over-watering.
• Real-Time Ambient and Leaf Temperature, and Humidity: In addition to VPD, this device captures real-time ambient temperature, leaf surface temperature, and relative humidity. Together, these readings form a complete climate profile to manage and optimize plant growth conditions more precisely.

2. Infrared Technology with 12-Point Laser Positioning

• The VPD Thermometer’s infrared sensor incorporates 12-point laser positioning, which highlights the exact area being measured, ensuring pinpoint accuracy. This laser-guided focus makes it easier to select specific plant leaves or surrounding air pockets for targeted readings, without any physical contact that could disrupt plant health.

3. First-of-its-Kind Compatibility with Smart Controllers

• This thermometer is uniquely designed to calibrate smart controllers that manage grow devices, such as lights, fans, and humidifiers. The precise VPD and temperature data allow these controllers to detect climate changes accurately, triggering environmental adjustments when needed. This integrated approach supports automated, real-time adjustments to maintain optimal growth conditions with minimal manual intervention.

4. Historical Data Tracking and Emissivity Adjustment

• Data Logging: The device automatically saves historical data, enabling users to track past readings and monitor climate changes over time. This feature is invaluable for detecting shifts in climate patterns, diagnosing environmental stress factors, and making adjustments to future growth cycles.
• Customizable Emissivity (0.1 - 1.00): By adjusting the emissivity setting, users can adapt the device to different surface materials, from plant leaves to grow tent walls. This ensures reliable temperature and VPD readings, as emissivity accounts for the material’s thermal radiation properties.

5. Instantaneous Readings with 12:1 Distance-to-Spot Ratio

• With a 12:1 distance-to-spot ratio, users can measure areas from a distance, maintaining accuracy without needing to be close to the plant. The <500ms response time provides nearly instant feedback, allowing growers to make rapid environmental adjustments to prevent climate stressors.
