The moisture meter can quickly measure the moisture content of the grain. （ pH meter with bluetooth） professional pH measurement, TDS(ppm), EC (conductivity), ORP, S.G, salinity (ppt) and Temp. Suitable for household drinking water, hydroponics, laboratory, aquarium. It can be used as a classic tester even if it is not connected to smartfona.Może be used as a classic tester even if it is not connected to a smartphone. （Cloud data management system ） accurate real-time Bluetooth data transmission and clear measured values make it easy to save, manage and share test data without fear of data loss. （Automatic pH calibration test） with high sensitivity of probe glass, full measuring range 0-14pH, 0.01 pH resolution can be obtained. Compared with other pH meters, pH is 3-point calibration method, and our pH is 5-point calibration method and equipped with powder calibration (asia Standard: pH 4.00, pH 6.86, pH 9.18 and Standard ue: pH 7.00, pH10.01), You can effortlessly calibrate to ensure the accuracy of measurements. （Comprehensive display） information just dip the pH electrode into the tested solution, the readings are quickly displayed on the large LCD display. （Multi-functional salinity tester） salinity range is 0-10000ppm, salinity tester has the function of automatic temperature compensation (32°f~140°f), which can reduce the error caused by liquid temperature change. （Easy to use） digital pH meter fully configurable parameter settings. The application can set upper and lower pH limits, which can be set according to your needs. When the set value exceeds the test range, the App interface displays the red value abnormally, notifying you of any values that exceed the set range.
