Introduction:

▶The instrument measures the photosynthetic effective irradiation intensity in the wavelength range of 400-700nm in natural light or simulated natural light. Mainly applicable to green plant growth photosynthesis effective wavelength range of irradiation intensity detection.

Parameters

▶Resolution: 1umol/m2-s

▶Unit: umol/m2-s for photosynthesis rate, 1mW/cm2 is equal to 46

▶Error range: ± (10%R+2dgt) R: reading (detection of composite light sources that approximate the sunlight spectrum)

In incandescent or monochromatic yellow light detection reading error will increase

▶Display: 3-3/4-bit LCD display, the maximum display value of 3999, overload display "OL"

▶Drift: less than ± 2% / year

▶Linearity: ±2%

▶Measurement range: 0-2700umol/m2-s (400-700nm)

▶Wavelength range: 400nm-700nm (fitted photosynthetic effective function)

▶Sampling rate: 2 times/s

▶Operating temperature and humidity: 0°C to 40°C Less than 80% RH

▶Storage temperature and humidity: -10°C to 50°C less than 70%RH

▶Size and weight: 132(L) 60(W) 38(H)mm, about 150g

▶Power source: 6F22 alkaline 9V battery (not included in the package)

▶Battery life: about 100 hours of continuous use
