SM206E-PAR Quantum Flux Meter with 400-700nm Wavelength Range Dual-Channel Detection and Peak Hold Function
The SM206E-PAR Quantum Flux Meter is a precision instrument designed to measure photosynthetic effective radiation intensity in natural light or simulated natural light within the 400-700nm wavelength range. This device is specifically engineered for detecting irradiation intensity in the effective wavelength range crucial for green plant growth photosynthesis.
With broad applications in agricultural production, scientific research, aquaculture, flower planting, and horticulture, this meter is particularly suitable for detecting simulated natural light sources used in underwater plant and ornamental plant cultivation and planting, including LED plant growth fill light verification.
- Peak hold function for maximum value capture
- Data retention capability
- Dual-channel detection of photosynthetically effective radiation
- Standard detection in air with optional waterproof probe for underwater applications
- Automatic probe recognition and measurement reading switching
