OK-SW1+ Soil Moisture Rapid Tester

I. Functions & Features
1. Small size, easy to operate with reliable performance
2. Whole course trace, long record time, integration of data collection and record, data kept in case of power break.
3. Low power consumption designed, a cell for renewal can be used for three months till one year.
4. Time interval for record be set freely from 1m to 100 days (recommend to set minute or more, the service life of cells is proportional to the time interval).
5. LCD with Chinese characters, waiting and sleeping modes. Support storage refresh automatically or by timing..
6. Professional data process, writing protection under low electricity, detection of storage fault, data restored after power break.
7. Flexible and efficient power supply management, and protection against reversed polarity of hardware and internal short circuit.
8. Work with DC power supply, double A battery, solar energy lead-acid cell, USB 5.0V simultaneously.
9. Host computer software will be available free of charge, through which, it is easy to check or output data or figures, Excel format is available for memory. The software components for display of diagrams and curves with one hundred thousand times of zooming, excellent in the display of curve trend and data details.
10. Communication of collectors can be configured flexibly, except USB (UART), it receives the customizing of RS485 communication.
11. Applicable Scope: it can be widely used in weather station, greenhouse, plant incubators, lab, cultivation houses and so on for environment monitoring.
