Instrument introduction
TZS-pHW-4G Soil Moisture, Temperature, Salinity and pH Tester is also called soil multi-parameter tester. It has a compact and beautiful appearance, which is easy to carry. It adopts light-touch buttons, large-screen dot matrix LCD display, and full Chinese menu operation; one-button operation Switch, you can manually record or set the sampling interval without the computer at any time, automatically record and store data; the probe is consistent, the sensor interface of different parameters can be exchanged, does not affect the accuracy; after the sensor is inserted into the host, there is no need to set it, and it will automatically search for more Different types of sensors.
Instrument use
The soil moisture temperature and salinity pH meter can detect and record the 4 parameters of soil temperature, soil moisture, soil salinity, and soil pH, including 4 parameter sensors.
Main features:
1. Wireless communication function: automatically upload measurement data, the device communicates with the server through 2G/4G network, and sends it to the server in real time. You can view the data on the web page. You can view and download the data no matter where you are on the Internet;
2. With mobile APP, supporting Android and Apple systems, you can view real-time data no matter where you are on the Internet.
3. Low power consumption design, increase system monitoring and protection measures to avoid system crashes.
4. Chinese liquid crystal display, can display the current date and time, the measurement data of each sensor, storage capacity, the number of stored data, and other information.
5. The host data storage capacity is large: the internal Flash of the device can store the latest 30,000 data, and the standard 4G memory card can store unlimitedly, and can also store the data in the Flash at the same time.
6. Built-in lithium battery power supply: 7.4V2.8Ah lithium battery, with charging protection, low voltage prompt function. The external power supply is 8.4V (above 1000mA) DC power supply.
7. Collection setting: Use it without guarding, you can set timed collection or manual collection.
8. Voice settings: You can set the voice broadcast function on/off/over-limit on as needed.
9. Voice alarm function: After the host’s voice is set to overrun, the overrun information can be broadcast by voice.
10. The host can connect to different types of sensors through the hub without affecting the accuracy of each other.
11. With GPS positioning function, the geographic coordinates of the collection point can be automatically displayed during data collection.
12. The type and quantity of the sensor can be expanded, up to 32 kinds (the expansion line is IP67, and the structure is integrated).
Manage cloud platform functions:
1. The self-contained instrument cloud management platform includes a C/S architecture, which can summarize and analyze the data of all portable devices and online devices, and data backup is not lost. The viewing operation methods include web pages and mobile phones (available for Android/Apple systems).
2. Display the data collected by each sensor, the detection time, and the GPS coordinate information of the collection location.
3. Data can be uploaded to the management cloud platform via 4G/2G network or USB data cable import. The data in the platform can be downloaded, analyzed, and printed;
4. The platform supports device data storage and provides sufficient capacity for long-term storage.
5. The platform provides report forms such as curves and tables for equipment data, and the data can be exported and imported.
6. The platform can combine data for report making, report printing, and report export functions.
7. The software can be upgraded online.
