VTSYIQI Chlorophyll Meter Tester Nitrogen Content Measurement Plant Nutrient Tester Instrument with Measuring Range 0.0-99.99SPAD Nitrogen 0.0-99.99mg/g Temperature -10-99.9℃ for Plant Green Degree Nitrogen Content Leaf Temperature Testing

VTSYIQI Chlorophyll Meter Tester Nitrogen Content Measurement Plant Nutrient Tester Instrument with  Measuring Range 0.0-99.99SPAD Nitrogen 0.0-99.99mg/g Temperature -10-99.9℃ for Plant Green Degree Nitrogen Content Leaf Temperature Testing

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 nitrogen fertilizer, and can protect the environment. It can be widely used in the research of plant physiological indicators and agricultural production.

Overview:

Rapid live detection of nondestructive plants, only the leaves can be inserted during measurement, and the leaves do not need to be picked without affecting the normal growth of crops. The leaves can be monitored in the whole process of crop growth, so as to obtain more scientific analysis results

High measurement accuracy (precision: ± 1.0 SPAD, repeatability: ± 0.3 SPAD), built-in anti-strong light interference system

All parameters can be measured simultaneously in one operation. Chlorophyll, nitrogen content and leaf temperature can be displayed simultaneously on the same screen and can be stored simultaneously

16GB large storage space, data can be stored, viewed and exported in groups

Multi-functional USB interface, can realize data export and charging function, can directly connect the instrument and the computer online, data export without the computer software, can also choose to use memory card to directly export data, the operation is simple and convenient

Data browsing: you can browse the historical data and delete the abnormal data on the instrument 7. High contrast LCD display can also clearly display data under strong lightLow power consumption mode design, built-in large capacity lithium ion charging battery, with anti-overcharge function, energy saving and etc.

Built-in Chinese and English bilingual display, one-button switch, seamless docking.

Standard configuration: host, charger, USB data cable, memory card, card reader, portable aluminum box, qualification certificate, instruction manual, etc
