Features

1.  It has better portability of transportation because it is small, light, and can be operated using by dry-cell batteries.
2. It is excellent at visibility feature by large liquid-crystal color display and has intuitive touch panel.
3. It is easy to exchange sensor by using connector.
4. Measured data is recorded to memory card and be able to record maximum of 100,000 records.
5. It specializes in measuring and recording and it achieves small size and low cost.

Product Overview

1.  Portable Data logger WDR-1, can measure Volumetric water content (VWC), electrical conductivity (EC), and temperature (℃) at the same time.
2. It can measure and analyze soil condition and could be brought out anywhere easily by combination with our company’s product, Small Water Sensor.
3. It runs with dry-cell batteries and be suitable to measure in difficult places to get the electrical power source.
4. Besides, put together with series of WD-3, it brings out special functions of the series of WD-3 to the utmost extent such as management of sensor and changing configuration.
