pH-8414 portable ph tester is supplied with an E201 pH composite electrode, 9V battery, buffers, protective box, and manual. The PH-8414 portable ph tester has been specially designed for the maximum facility of use. The handy keyboard for the selection of the various functions. The possibility of automatically correcting errors in measurement due to temperature. The display on the front panel reveals the temperature and PH or mV reading taken by the instrument. Moreover, the PH-8414 portable ph tester has low battery indicators.
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 that must be kept hydrated and a reference junction that 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, the storage solution has the same chemical makeup as what is in the electrode itself, but if that is not available use buffer 4 or 7 solutions. 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.
