Main highlights

Three different modes: Switch between output of results in TDS (ppm) or EC (μs) at the touch of a button. In addition, the device is able to indicate the temperature of the measured liquid in Celsius or Fahrenheit.
Ready for immediate use: Our conductor meter is already pre-calibrated from the factory. After switching it on, you can start measuring immediately. Post-calibration is possible at any time via the screw on the back of the device.
Quick measurement of solvent materials: The gauge is able to measure the electrical conductivity of the water (EC). From this value, the number of solids TDS (Total Dissolved Solids) can also be determined.
Perfect readability guaranteed: Thanks to the practical hold function, measuring results can be frozen for easy reading. The brightly illuminated display makes it much easier to operate the conductivity meter especially in the dark or under strong light incidence.
Accurate measurements: The MEASURY TDS&EC meter measures the conductivity (EC) of 0 - 9,990 μs/cm and the TDS value of 0 - 9,990 ppm. Resolution: 1μs/ppm from 0 - 999, 10 μs/ppm from 1,000 - 9,990. The accuracy of the measuring device is ± 2 %.

Main highlights

Widely used: pH test can measure in swimming pools, salt water pools, hot tubs, SPAs, aquariums, aquacultures, the pH meter can measure the EC and pH value of hydroponics. TDS and pH meters measure liquids such as permeate water, pool water, drinking water, tap water, irrigation water, pond water, garden water, coffee, fruit juice, brewed wine and beer
User-friendly design: the backlight ensures that you can use the product in dimly lit working environments. With the HOLD/TEMP button, you can record the reading, and the backlight turns off within 30 seconds. Press any button to turn on the backlight again
Calibration The unit is factory calibrated and supports automatic 3-point calibration with the included standard calibration kit (4.01 / 6.86 / 9.18 pH). In order to compensate for transport influences and ensure high measurement accuracy, it is recommended to perform the calibration according to the instruction manual at the first use
Automatic temperature compensation: the pH meter does not need to pay attention to the temperature of the test liquid; this device can accurately measure sample values within the temperature range of 0 °C - 60 °C (32 °F-140 °F), causing the problem of inaccuracy due to liquid temperature changes. Whether in winter or summer, you can get accurate values
5-in-1 pH meter: a digital water tester drinking water can measure pH, salinity, EC, TDS and temperature; simply press the (MODE/CAL) button to switch between pH, salinity, EC and TDS and read values. Long press the HOLD/TEMP button to switch between the units temperature and Celsius. Meets the requirements for regular, daily monitoring of water quality and allows you to be informed about the situation of water quality at any time
