Description
xThe AC Infinity VPD Thermometer is a handheld environmental monitor that measures air and plant leaf VPD, ambient temperature, leaf temperature, and relative humidity to help you tune your grow-room climate.
Designed for growers who want faster, more precise feedback than standard thermometers or hygrometers, this compact device combines infrared leaf temperature sensing with ambient probes and VPD calculation. Its 12-point infrared targeting laser lets you pinpoint the exact leaf area you want to read, while onboard memory stores previous readings so you can track trends without manual logging.
How does the VPD Thermometer measure both air and leaf VPD?
The unit pairs ambient temperature and relative humidity sensors with a non-contact infrared reading of leaf surface temperature. It calculates VPD from those values and displays both air VPD and leaf VPD, giving a clearer picture of transpiration stress than ambient numbers alone.
- Ambient temp and RH sensors for accurate environmental input
- Infrared leaf temp readout using 12-point laser positioning
- Automatic VPD calculation (air and leaf) shown on a single screen
What makes the infrared targeting system useful for growers?
The 12-point laser grid highlights the exact measurement area so you avoid reading non-leaf surfaces or mixed backgrounds. That precision helps produce repeatable leaf temperature readings for reliable VPD comparisons between plants or across time.
- Laser grid shows the exact spot for non-contact measurements
- Reduces errors from mixed backgrounds, soil, or reflective surfaces
- Useful for checking individual leaves, canopy sections, or specific plants
How does the device help with climate control and data tracking?
The VPD Thermometer stores historical readings automatically so you can spot trends and make incremental controller adjustments. Use its saved data to calibrate smart controllers or to validate changes made to ventilation, irrigation, or lighting schedules.
- Automatic history saves previous measurements for trend analysis
- Data supports calibration of smart controllers and environmental systems
- Portable form factor makes spot-checking fast across rooms or tents
How portable and practical is this tool for everyday grow maintenance?
Lightweight and handheld, the thermometer fits easily in a pocket or tool kit for routine inspections. Its clear display and quick-read sensors make it practical for daily checks without interrupting workflows.
- Compact handheld design for on-the-spot diagnostics
- Quick-response sensors deliver immediate feedback
- Useful for hobby growers to commercial operations for spot measurements
Who is this for: The AC Infinity VPD Thermometer is intended for indoor gardeners, greenhouse operators, and anyone using smart environmental controllers who needs accurate leaf and air VPD readings. It’s especially helpful for growers who want to refine transpiration-related adjustments, validate controller behavior, or maintain consistent microclimates without complex sensor arrays.
FAQ
Q: Can this device measure leaf temperature without touching the plant?
A: Yes. It uses infrared sensing with a 12-point laser grid to non-contact measure leaf surface temperature accurately.
Q: Will it store previous readings for trend tracking?
A: Yes. The thermometer automatically saves historical readings so you can review shifts in climate conditions.
