Plant Transpiration Rate Meter PTRM-1000 (CAT#: STEM-OEM-0365-ZJF)

This portable plant physiological meter simultaneously measures multiple parameters including air temperature, leaf temperature, air humidity, and photosynthetically active radiation (PAR). It calculates transpiration rate and stomatal conductance based on the collected data. With interchangeable leaf chambers, it is suitable for diverse plant types including field crops, fruits, vegetables, and grasses. Its lightweight design enables convenient one-person field operation.
