Multi-functional water quality tester

EZ-9909 is a new multi-functional water quality test instrument, which can measure pH, TDS,EC, salinity value and temperature. The measurement range is large and wide, which can measure both freshwater salinity and sea salt

Features:

【5-in-1 Water Quality Tester】Digital pH tester has the functions of monitoring TDS, pH, salinity, EC meter and temperature measurement. TDS measurement range: 0-1000ppm, EC measurement range: 0-10000US / cm, PH measurement range: 0.01-14.00pH, salinometer measurement range: 0.00-25.00%, temperature conversion function.

【High Accuracy】High-accuracy algorithm chip and electrode of our digital water ph tester ensure an accurate and fast response. When the measured value is stable, just press the HOLD/TEMP key to lock the measured value and take it out for viewing, which is really simple.

【Two Salinity Meters】Digital PH meter can detect the salinity of edible salt. At the same time, it can detect the salinity of seawater. Food salinity measuring range: 0.00-25.00%, seawater salinity measuring range: 10.1-200.0ppt.

【Automatic power-off function & large screen display】PH tester has a backlight LCD that helps you clearly see the measurement in any case. The automatic power-off function turns off the power after 5 minutes without any operation to save power. Employs a fully transparent liquid crystal (LCD) to display 4-digit values and the corresponding physical quantity units.

【Automatic Temperature Compensation】Temperature can affect reading levels, Digital PH Meter for water hydroponics has an even better range of 0 °C-60 °C (32 °F-140 °F), automatic temperature compensation can ensure that you are getting the best reading, so you can test with confidence in any environment.

Note: Every time you use this, you will need to clean the electrode.

Battery: LR44*3(Not include)

With backlight function, it can be tested at night

The waterproof grade is IP67, at normal temperature and pressure, when the shell is temporarily immersed in 1M water will not cause harmful effects

Wide range of application

products can be used in swimming pools, spas, family kitchens, laboratories, farms, aquariums

Usage and calibration procedure as well as usage precautions

Noted:Always clean the electrode after use
If the pH calibration cannot identify the solution, the electrode is broken
