Although this METER is a complex and delicate instrument,its durable structure will allow many years of use if proper operating t e c h n i q u e s a r e developed. Please read t h e f o l l o w i n g instructions carefully and always keep this manual within easy reach.
5. Start the calibration on the meter. 6. Wait for a stable reading in the pH 10.01 buffer, at least 1 to 2 minutes. If the temperature of the buffer was entered manually or an ATC probe is in use, the meter should automatically recognize the buffer and display its temperature-corrected...

The meter is factory pre-set at 7.00, 4.01 and 10.01pH. To change the buffer set, turn off the unit, then press and hold the “STAND” key while turning on the unit again. [Note: There is no need to repeat this procedure every time the unit is power up unless one decides to ...
Probes, or electrodes, for your pH meter generally last 12-18 months. This holds true whether the probe is being used or not. The "lot code" will determine the age of your pH probe. A lot code is two numbers then a letter. The numbers indicate the year of manufacture and the lette...
Calibrating the pH meter correctly ensures the electrode inside the pH probe has not drifted off or is damaged. Inaccurate pH readings come from poor calibration, storage, and cleaning of the pH meter. These quality and safety methods are part of the standard operating procedure (SOP) when cali...
A pH meter is an instrument used to measure acidity or alkalinity of a solution - also know as pH. pH is the unit of measure that describes the degree of acidity or alkalinity. It is measured on a scale of 0 to 14. The quantitative information provided by the pH value expresses the...
3.1Samples with very low or very high pH may give incorrect readings on the meter. For samples with a true pH of >10, the measured pH may be incorrectly low. This error can be minimized by using a low-sodium-error electrode. Strong acid solutions, with a true pH of <1, may give ...
