This product is an instrument to measure the photosynthetic effective radiation intensity in the natural light or simulated natural light in the wavelength range of 400-700nm. It is mainly applicable to the detection of the irradiation intensity in the effective wavelength range of green plant growth photosynthesis. It has a wide range of uses in agricultural production and scientific research, aquaculture, flower planting, horticulture, etc. It is especially suitable for the detection of simulated natural light sources for underwater plant and ornamental plant cultivation and planting (such as detecting LED plant growth fill light).
Feature:
1.Peak hold function
2.Data retention function
3.Dual-channel detection of photosynthetically effective radiation,
can routinely detect in the air and equipped with a waterproof probe for underwater detection.
4.The optional waterproof probe automatically recognizes and automatically switches to the measurement reading.
