Soil Temperature, Moisture, Salt Level Tester, Accuracy: ±0.5°C, Test Range: -40～100°C, Response time: ≤ 2 seconds

Soil Temperature, Moisture, Salinity Speed Tester Features:
Handheld features: 
1. Small and beautiful and easy to carry, touch buttons, large-screen dot matrix LCD display, full Chinese menu operation. 
2. One-touch switching, you can manually record or set the sampling interval at any time from the computer, automatically record the data and store it. 
3. AC and DC dual-use, either to get the field at any time measurement data collection, but also can be placed for a long time to record the location. 
4. With GPS positioning, automatic data acquisition, real-time display of geographical coordinates of the location (latitude and longitude information) and save. 
5. With voice broadcast function, you can set the voice alarm for the limit value, the real-time standard voice broadcast over the standard parameters, and you can directly broadcast real-time environmental parameter values​(optional). 
6. Data saving function is powerful, with voice alarm function, GPS function can store up to 12,000 sets of data. 
7. You can view the data on the host or import it into the computer for viewing. 
8. After the unexpected power failure, the data that has been saved in the host is not lost. 
9. The probe has consistency, different meteorological parameters of the sensor interface can be interchanged, does not affect the accuracy. 
10. After the sensor is inserted into the host, you can manually search for a variety of different types of sensors (similar to the U disk and the computer can automatically sense the connection). 
11. The instrument has 256-channel simultaneous detection of extended functions, can achieve multi-point synchronization detection, can be combined on demand. 

Pc Software Functions: 
1. Display the curve trend of each parameter process. The maximum value, minimum value, and average value are displayed for viewing, zooming in and out. 
2. It has the feature of setting out-of-range colouring, which is more intuitive and more convenient for customers. 
3. Can store the data recorded in EXCEL format backup and save for later calls. 
4. Reports and graphs for each parameter can be selected for viewing in the period of time and can be printed by computer.
5. Curve coordinates can be set and moved by themselves, and the analysis of history is clearer and the time is clearer. 
6. Fully compatible with all 32-bit Windows systems on the market.
