Product information

Description

Digital water tester 5in1 EZ9909SP measures pH, conductivity (EC), TDS, salinity and temperature. Designed for use in swimming pools, wells and laboratory environments, the EZ9909SP offers fast readings on a clear color display without the need for test strips. The compact handheld device comes with an electrode protective cover and accessories for calibration solution preparation.

Advantages

The EZ9909SP provides five measurements in one compact instrument, reducing the need for multiple devices. Its large LCD color display and fast response make readings easy to interpret. Automatic temperature compensation (ATC) ensures more accurate conductivity and TDS values, while manual pH calibration allows adjustment for greater precision. Battery-powered operation with LR44 cells makes the tester portable and convenient for field or laboratory use.

How to use

Install three LR44 batteries and attach the electrode protective cover. Rinse the electrode with distilled water before measurement and immerse the sensor into the sample to the recommended depth. Allow the reading to stabilise on the display; use manual pH calibration with supplied calibration solution bags as needed to ensure accuracy. After measurements, rinse and dry the electrode, replace the protective cover and store the tester in a dry place.

Recommendations

For reliable results, calibrate the pH electrode regularly using appropriate buffer solutions prepared with the supplied calibration bags, avoid extreme contamination of the sensor, and replace batteries when the low battery indicator appears.
