Henan University (HENU), located in Zhengzhou and Kaifeng, Henan Province, China, is a public university jointly established by the Henan Provincial People's Government and the Ministry of Education of the People's Republic of China.
Soil Testing Instrument Features:
1. Operating System: Android 5.1 operating system, quad-core processor, CPU frequency ≥1.8GHz, 16GB large-capacity memory, fast operation, strong stability, no lag or freezing, and the software comes with a computer software copyright certificate provided by the manufacturer.
Built-in bilingual display (Chinese and English), one-click switching, seamless integration.
2. Dual protection with password and fingerprint login, multiple accounts can be set up as needed to ensure the security and classification of test data.
3. Equipped with dual USB interfaces, allowing export of historical test data.
Data is presented in tables when viewed on a computer.
4. Simultaneously configured with an online cloud agricultural data center for soil testing and fertilizer recommendation system, facilitating managers to calculate fertilization standards even without test data.
5. Equipped with a WeChat mini-program for viewing all historical uploaded data.
An external voltage display panel directly shows the real-time detection voltage, ensuring a stable detection environment and guaranteeing detection accuracy. It also features power-off protection, automatically saving data in case of sudden power failure to prevent data loss.
6. A 4-channel fixed colorimetric cell (solid-state module) is integrated with the instrument, eliminating mechanical displacement and wear. To ensure detection accuracy, the channels must be consistent with the light source, with exactly four detection channels.
7. The colorimetric cell is built into a sunken, sealed chamber, completely covered by a 15.7cm diameter circular light-shielding plate to prevent light leakage during experiments, ensuring accurate detection results.
8. Patent No.: ZL 2022 2 0923165.6 Leaf Area Meter Features and Main Unit Introduction: This is a portable instrument that is easy to use and suitable for fieldwork.
It can accurately, quickly, and non-destructively measure the leaf area and related parameters of leaves, and can also measure the area of harvested plant leaves and other sheet-like objects. Widely used in agriculture, meteorology, forestry, and other fields.
The instrument can directly measure leaf length, width, and area, and integrates GPS positioning and a 4G wireless transmission system. It also features a Type-C interface, allowing measurement data and location information to be simultaneously imported into computers and cloud data platforms, facilitating further data processing by researchers.
