JTM301 Wireless Thermo-Hygrometer VPD data logger VPD meter

JTM301 Wireless Thermo-Hygrometer VPD data logger VPD meter

JTM301, an advanced multifunctional data logger designed to monitor temperature, humidity, and VPD with built-in Bluetooth connectivity. It enables growers to precisely optimize growing conditions for healthier plants and higher yields.

Featuring flexible installation options, the JTM301 can be wall-mounted, placed on a desktop, or attached magnetically to metal surfaces. Ideal for a wide range of applications including indoor growing spaces, greenhouses, grow

tents, and cold chain transportation.

Applications:

1. Agriculture: Real-time monitoring of temperature, humidity and VPD (Vapor Pressure Deficit) to provide the best environmental support for crop growth.

2. Warehousing and logistics: Ensure the stability of the storage environment for goods and prevent losses caused by abnormal temperature and humidity.

3. Family life: Create a comfortable and healthy home environment to safeguard the breathing and comfort of family members.
