  • RCYAGO 4-in-1 Digital pH Meter with ATC, pH/ORP/H2/TEMP Meter, ±0.005 pH Accuracy, 0-14.0 pH Measurement Range
    Bestseller #1
    RCYAGO 4-in-1 Digital pH Meter with ATC, pH/ORP/H2/TEMP Meter, ±0.005 pH Accuracy, 0-14.0 pH Measurement Range (58)
      4-in-1 Water Quality Test: With RCYAGO 4-in-1 pH tester, which can measure PH, ORP, H2, and Temp value with high precision at the same time. All-round measurement of water quality to ensure healthy water quality. ±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. 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. PH Tester with Wide Application: Ideal for household and laboratory pH testing applications, including drinking water, swimming pool, pond, aquariums, hydroponics, laboratory, etc.
