Bluetooth Multifunctional Water Quality Meter ----- is a professional Acidity Meter that accurately measures PH, TDS, EC, CF and TEMP. Unlike ordinary water quality pens, the product has Bluetooth function. Download APP and connect successfully. You can view and control the water quality measurement data in real time in APP. More intelligent is that the product can also be viewed at any time, as well as storage and management of measurement data, and even share the measurement data, you can compare the results of the measurement through the table to better analyse the water quality. The large screen display with clear, easy-to-read values is suitable for pH testing in a wide range of industries and is often used to test drinking water quality, monitor swimming pool quality, PH balance measurements in RO/DI systems, nutrient solutions, aquariums, spas, hot tubs, or hydroponics, aquariums, swimming pools, fish tanks, and ponds in gardens.
The professional Food PH Meter ----- Product uses a sensitive metal probe and is not just used to measure say, food, meat, canned goods, jams, bacon, cheese, milk, fruit juices, fruit, vegetables and more. It can even be used to measure cosmetics, soil, bread, etc...
The Precision pH Tester with Effective ATC ----- Features Effective temperature compensation (ATC) to ensure fast response and accurate test results.
Mobile App Bluetooth ----- The APP is compatible with Apple and Android. Switch mobile phone language and region to automatically convert different words on the App.
Reliable PH Meter, Accurate and Fast Measurement ----- The acid-base reaction of food directly affects the health of human body, and the PH measurement can maintain the balance of the body at any time; soil PH value is very important for the growth of crops, and healthy soil will maintain a certain acid-base balance.
Reliable EC Meter , Accurate and Fast Measurement----- Water quality tester has a test range of 0-19900us/cm and 0-199.0ms/cm , In fact, water quality is closely related to health. Good water quality can slow down aging, protect the health of the elderly, protect the health of pregnant women and take care of the health of babies.
Reliable TDS Meter, Accurate and Fast Measurement ----- Water quality tester has a testing range of 0-19900ppm and 0 -199.0 ppt , water quality TDS value PPM is x milligrams of dissolved solids contained in 1 litre of water, which is convenient for your different water quality testing needs and ensures clean drinking water.
Reliable CF Meter, Accurate and Fast Measurement -----CF Corresponds to hydroponics is very important! Nutrient solution is the key to soilless culture, and different crops require different nutrient solution formulations. Simply switch on the meter and measure the nutrient solution easily.
