4/3/2 in 1 Optional PH ORP H2 Temperature Hydrogen-rich Meter Portable Pen Water Quality Purity Tester for Aquarium Hydroponic

Please note there are three models to choose from: 4 in 1, 3 in1, and 2 in1(Optional)

Description 4 in 1 PH/ORP/H2&TEMP Hydrogen-rich Meteris a newly developed high-precision multifunctional water quality tester, which has the functions of measuring the PH, ORP, hydrogen ion concentration, and temperature of the water. The automatic temperature compensation (0-60℃) measurement data is updated. Accurate, easy to operate, easy to carry, drinking plenty of water rich in hydrogen ions is good for health.

Specifications 1.PH Range: 0.01-14.00pH Resolution: 0.01pH Accuracy: ±0.05pH

2.ORP Range: ±999mV Resolution: 1mV Accuracy: ±2mV

3.H2 Range: 0-2400ppb; 0.001-2.400 Resolution: 2ppb; 2ppm Accuracy: ±10ppb; ±10ppm

4. Temperature Range: 0.1-60.0°C 32.0-140°F Resolution: 1℃/°F Accuracy: ±0.5 Feature ±0.05 pH accuracy and three-point calibration] High-sensitivity glass probe, the pH meter uses a 3-point calibration method to calibrate the electrode to pH 4.00, pH 6.86 and pH 9.18 solutions to ensure the accuracy of your measurement.Temperature: automatic temperature compensation 0-60℃ Working environment: 0-60℃ (32.0-140°F); RH 100% Waterproof: Ip67 Automatic shutdown: 5 minutes Data retention: value retention Battery: 3*1.5V (LR44)(not including battery) 3 in 1 ORP H2 Temperature Hydrogen Ion Concentration Tester

Description a. Hydrogen Water is Rich hydrogen water,Aqua means hydrogen. b. Common sense tells us that hydrogen is insoluble in water.In fact, hydrogen is not insoluble in water, it's just extremely insoluble. c . If you do it in molarity,The concentration of 101.325kPa pure hydrogen dissolved in water at 20℃ was 0.92mmoI/L d . With the invention and application of nanometer gas-liquid mixing technology in China, the scientific problem of hydrogen insoluble in water has been solved, and the hydrogen molecule is evenly coated in water by physical method to promote the stable combination of hydrogen and water.It has the characteristics of high hydrogen concentration and good stability.
