Electrode: Replaceable1. pH Meter with Bluetooth: Powered by the mobile App, professional measurement of H2, and Temp. The mobile phone can control the backlight. Drinking water, Aquarium, Fish Tank, Swimming Pool, Farmland irrigation, Laboratory Etc.2. Cloud Based Data Management System: Precision real-time Bluetooth data transmission, Synchronize save time and data record, Share data or print excel tables, the mobile phone can view the calibration record.3.Automatic Calibration H2 Tester: With high sensitive replaceable probe, easy to operate, can measure 0-2990 ppb; 0.00-2.90 ppm, accurate to 1ppb; 0.01 ppm, automatically calibrate H2.4. H2 Meter with Automatic Temperature Compensation: Temperature can affect reading levels, digital pH tester has an even better range of 0.0C-60.0C (32.0F-140.0F), automatic temperature compensation can ensure that you are getting the best reading, so you can test with confidence in any environment.5. High Accuracy Water Tester: High-accuracy algorithm chip and electrode of our digital water quality tester ensure an accurate and fast response. EU CE certification, Chinese / English switching, backlit LCD design, read the measurement results at any time. One key to lock the reading function, you can view the data at any time. Can be set to automatically/manually save data. It can detect water data changes for a long time, and automatically set the time interval for recording measurement results. You can set the maximum and minimum values. When the measurement result is not within the set range, the value will be displayed in red.6.The content of dissolved hydrogen in water has become one of the indicators for determining hydrogen-rich water. The hydrogen content detection pen is developed for measuring the dissolved hydrogen content in the hydrogen-containing water generator and the generator, and measures the dissolved hydrogen content in the water body. Suitable for hydrogen-rich water machine, hydrogen-rich water cup, hydrogen-rich water stick, hydrogen-rich kettle, etc.
