Apera Instruments PH60F Premium pH Pocket Tester with Replaceable Flat Sensor, for Skin, Fabrics, Paper's pH Testing, ±0.01 pH Accuracy, -2.00-16.00 pH Range

The Apera Instruments PH60F Premium Pocket pH Tester simply tests pH level for skin, fabrics, paper, carpet, and other surface containing liquid in an ACCURATE, QUICK, & Professional manner (Also works great for regular water solution's pH testing). The flat probe has a Triple-Junction structure that prevents clogging, and is replaceable.

Up to 3 points (4.00, 7.00, 10.01) of Auto Calibration with auto buffer recognition and 0 to 50˚C Auto Temperature Compensation (ATC), ±0.01 pH, 0.5˚C accuracy with -2.00 to 16.00 pH measuring range, auto recognition and reminders of stable values improves consistency, saving you the trouble of guessing when to manually hold measurement (auto hold function available).

The meter is CE certified and comes with a 2-YEAR Warranty (6 months for the probe). The company designs and manufactures scientific analytical instruments like meters and sensors for pH, conductivity, turbidity, and dissolved oxygen for over 25 years, and meets ISO 9001:2008 Standards.

NOTES: The instrument will NOT give accurate or stable readings for distilled or deionized water's pH testing. This is because distilled and deionized water do not have enough ions present for the electrode to function properly. To measure distilled or deionized water’s pH, users need to use a specialized pH electrode. Do NOT store the probe in distilled water or deionized water because they will cause damage to the glass membrane of the pH probe. Only use distilled water for cleaning the pH probe.
