Aquarium digital PH meter PH-025
• DC 6V with an adapter type or 4* 1.5V (AG13) type
• Can be used online
• Long line waterproof electrode
• Easy 1 or 2 point manual calibration
• 500 hour battery life
• Simple to use
PH-025 is so popular in aquarium, swimming pool and water treatment fields because of its low price, high quality waterproof electrode and mini shape.
Calibration is performed manually at 1 or 2 point with a trimmer located on the side of the tester.
You can chose adapter type or battery type, with a battery life of 500 hours of continuous use, PH-025 will provide weeks of last testing online before the batteries need to be replaced.

What is pH?
A pH (potential of Hydrogen) measurement reveals if a solution is acidic or alkaline (also base or basic). If the solution has an equal amount of acidic and alkaline molecules, the pH is considered neutral. Very soft water is commonly acidic, while very hard water is commonly alkaline, though unusual circumstances can result in exceptions. The pH scale is logarithmic and runs from 0.0 to 14.0 with 7.0 being neutral. Readings less than 7.0 indicate acidic solutions, while higher readings indicate alkaline or base solutions. Some extreme substances can score lower than 0 or greater than 14, but most fall within the scale.
Does my pH electrode have to be wet?
All glass electrodes have a bulb which must be kept hydrated and a reference junction which must be kept wet to prevent excess leakage of the internal electrolyte solution from the reference junction.
What should I store my pH electrode in?
Ideally, storage solution since it has the same chemical make-up of what is in the electrode itself, but if that is not available use buffer 4 or 7 solution. NEVER STORE IN PURE (DISTILLED) WATER!!! In the case of electrodes that are continuously immersed, storage is not an issue since they are constantly wet.
