About this item

• 4 IN 1 PH METER - This set includes a pH meter and a TDS meter to measure pH value, total dissolved solids (TDS), electrical conductivity (EC), temperature and mineral content. These two measuring tools allow you to accurately and quickly determine all aspects of water quality in seconds.
• High accuracy: with the pH meter, pH values from 0.00 to 14.00 can be determined with an accuracy of ±0.05. The conductivity meter can determine EC values of 0-9990μs/cm and TDS values of 0-9990ppm with an accuracy of ±2%.
• Automatic calibration: Both gauges can be calibrated at the touch of a button. Simply insert the device into the appropriate solution and turn on the "ON/OFF" button. After a few seconds, the meter is recalibrated.
• EASY TO USE - Press the "Hold" button, the TDS PH meter locks the measurement and automatically turns off after a few minutes of inactivity. The two meters have a convenient backlit LCD display that makes it easy to read data even in the dark.
• Wide range of applications: pH meters and TDS testers to test water quality and pH value, suitable for testing drinking water, tap water, wine and distilled water. It can be used in various scenarios such as aquariums, swimming pools, spas, hydroponics, laboratories, chemical industry, agriculture, fishing, etc.
