Brief introduction: Apogee announced that the technology of nondestructive detection of chlorophyll content in plant leaves is a great advance in the industry. Based on research by scientists at the State University, Apogee has developed an optical chlorophyll meter that measures leaf chlorophyll in the unit I "μ mol". A nonlinear output index related to chlorophyll in leaves. Technical specifications: Type: MC-100 Display output: "μ mol" leaf chlorophyll per square meter Measurement area: 63.6 mm2 / 9.0mm standard diameter 19.6 mm2 / 5. 0mm after reduction) Resolution: ±10 μ mol m-2 Linearity: ±1% Repeatability: ±1% Acquisition time: 3 S Memory: 8m memory, 94000 data Working environment: 50 ℃ Power requirement: standard 9V DC alkaline battery Size: 152mm long 82mm wide 25mm tall
