The TPZT-1000 is a high-precision, portable device for measuring plant transpiration and stomatal conductance. It simultaneously monitors air/leaf temperature, humidity, and PAR, providing instant calculations for critical plant physiology parameters.

Featuring a user-friendly interface with real-time data display, its compact design (3.25kg) ensures easy field operation. The customizable leaf chamber adapts to various plants, from crops to vegetables, while robust construction withstands harsh conditions (0-100% RH, 20-50°C).

With lab-grade accuracy (±0.2°C, ±3% RH) and 9-hour battery life, the TPZT-1000 delivers reliable data for research in agronomy, ecology, and irrigation optimization—all at a competitive price.

Feature：

Multiple parameters tested: test air temperature, leaf temperature, air humidity, PAR etc at same time,and count the transpiration rate and Stomatal conductance accordingly.
Intelligent: Menu display and Cursor operation; test process and results displayed in real‐time, withsmall size, light, portable and one‐person operation.
Widely application: with different leaf chamber, the meter is able to be used in field crops, fruit andvegetables, hay etc which are in different shape

Cost‐efficiency: very competitive price and convenient maintenance
