VTSYIQI Chlorophyll Content Meter Handheld Chlorophyll Meters with Measuring Range 0.0-99.99SPAD Nitrogen 0.0-99.99mg/g -10-99.9℃ for Chlorophyll Content Nitrogen Content and Leaf Temperature

VTSYIQI Chlorophyll Content Meter Handheld Chlorophyll Meters with Measuring Range 0.0-99.99SPAD Nitrogen 0.0-99.99mg/g -10-99.9℃ for Chlorophyll Content Nitrogen Content and Leaf Temperature About this item: Measuring range: Chlorophyll: 0.0-99.99SPAD; Nitrogen content: 0.0-99.99mg/g; leaf temperature: -10-99.9℃ Measurement accuracy of chlorophyll: within ± 1.0 SPAD units (at room temperature, the SPAD value is between 0-50); Nitrogen content: ± 5%; foliar temperature: ± 0.5℃ Repetitive chlorophyll: within ± 0.3 SPAD units (SPAD values between 0-50); Nitrogen content: ± 0.5mg/g;leaf surface temperature: ± 0.2℃ The plant nutrient tester can instantly measure the relative content of chlorophyll (per unit SPAD) or green degree, nitrogen content, leaf temperature, so as to understand the real nitro requirement of the plant and understand the lack of soil nitro or whether the nitrogen fertilizer is excessively applied. This instrument can be used to increase the utilization rate of nitroge
