Biobase SKU: PTRM-1000

Product Description

The Biobase PTRM-1000 is a portable, multifunctional instrument designed for accurate measurement of plant transpiration rate and stomatal conductance. With integrated sensors for air temperature, leaf temperature, relative humidity, and photosynthetically active radiation (PAR), the PTRM-1000 enables researchers, agronomists, and crop managers to evaluate plant water status and physiological performance in real time. Compact, lightweight, and easy to operate, it is suitable for use in laboratories, greenhouses, and field applications across a wide range of crops, fruits, vegetables, and forages.

 

 

Key Features

  • Multiple parameters in one device – measures air temperature, leaf temperature, relative humidity, and PAR, with automatic calculation of transpiration rate and stomatal conductance.
  • Portable and user-friendly – compact design, lightweight, and suitable for single-person operation in the field or lab.
  • Versatile applications – compatible with different leaf chambers to accommodate various plant types including field crops, vegetables, fruit trees, and forage grasses.
  • Accurate and reliable – provides precise measurements across a wide environmental range for dependable plant physiology research.
  • Long battery life – powered by a rechargeable DC 7.4V Li-ion battery for up to 9 hours of continuous operation.
