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.
