Overview

Plant Photosynthesis Meter LMPPM-A202 operates at relative humidity of 0 to 100%. It simultaneously measures photosynthetic rate, transpiration rate, CO₂ concentration, humidity, temperature, and radiation. Its digital humidity and temperature sensors ensure high-quality monitoring of moisture and ambient temperature. It features silicon photocell with correction filter to measure photosynthetically active radiation reliably. Our Plant Photosynthesis Meter is ideal for research in biology, agronomy, horticulture, forestry.
