Feature
●4-in-1 Water Quality Test: RCYAGO 4-in-1 pH tester, which can measure PH, ORP (Oxidation-reduction potential), H2 (Hydrogen content), and Temp value with high precision at the same time, simply press the {MODE/CAL} key to switch the readings of pH, ORP (mV), and H2 (ppb/ppm).
●±0.05 pH Accuracy and 3-Point Calibration: It has a high-sensitivity glass probe, the full measurement range of the RCYAGO pH meter is 0-14ph, and the pH resolution is 0.01. And the pH meter uses the three-point calibration method to calibrate the electrode to the solution of pH 4.00, pH 6.86, and pH 9.18 to ensure the accuracy of measurement. ORP and H2 meters are pre-calibrated.
●PH Meter with Automatic Temperature Compensation: Temperature will affect the reading level, and automatic temperature compensation can ensure that you get the best reading. compared with other pH meters for water, there is only a range of 0°C-50°C. our digital pH meter has a better range of 0°C-60°C (32°F-140°F). therefore, it can solve the possible errors caused by the perfect change of liquid temperature, so as to make the pH reading more accurate.
●Automatic Power-Off Function & Backlit Display: The automatic power-off function turns off the power after 5 minutes without any operation to save power. The pH meter features a green backlit LCD to help you obtain the measurement results clearly in any situation. Press the "HOLD/TEMP" key to lock the reading, helping to easily record the reading.
●PH Tester with Wide Application: Ideal for household and laboratory pH testing applications, including drinking water, swimming pool, water treatment, pond, water purification, aquariums, hydroponics, laboratory, etc.
Description
RCYAGO 4-in-1 Digital PH ORP H2 Temp Meter
How to Calibrate the PH Meter?
1. Before calibration, prepare 3 beakers containing separately 250ml of pH 4.00/pH 6.86/pH 9.18 standard solution.
2. Rinse the electrode with clean distilled water and wipe it dry. Turn on the pH meter and adjust to pH mode.
3. Immerse the electrode into the pH6.86 buffer solution, wait for the value to stabilize, press "CAL" for 5s, and the screen will display "CAL", when pH6.86 flashes 3 times, the calibration of pH6.86 is finished.
4. Repeat the above steps to calibrate pH4.00 or pH9.18.
Product Details
High Accuracy Electrodes
The role of the reference electrode is to determine the potential difference between the measuring electrode and the liquid by comparing it with the measuring electrode, and calibrate it to ensure accurate measurement results.
LCD Backlit Display
The pH meter adopts the green backlight LCD design, which can easily read the test results regardless of the light; Press and hold the "HOLD/TEMP" button for 5 seconds to convert to Celsius or Fahrenheit degrees.

pH Tester for Hydroponics
The ideal pH range for nutrient solutions is generally between 5.5 and 6.5, which helps plants grow.
-
ORP range reference value for common applications:
Drinking Water: ±50mV
Swimming Pool Water: +650mV to +750mV
Sewage Treatment: -100mV to +100mV
-
Hydrogen Tester
Testing the H2 content of drinking water can let us know the quality, choose a healthier lifestyle.
Wide Application
Measure the H2 hydrogen content of drinking water. Knowing the concentration of H2 hydrogen in the water allows for a better choice of drinking water.
The ORP meter measures the potential value of the redox process in swimming pool water. The ideal range for ORP values is usually between 650~750mV.
If the pH of the nutrient solution is too high or too low, it is not conducive to nutrient uptake and utilization by the plants.
The higher the ORP value of the liquid, the more oxidizing it is. The lower the ORP value of the liquid, the more reductive it is.
