HI70009C HANNA BUFFER SOLUTION น้ำยาแบบซอง pH9.18

Description

The pH 9.18 buffer solution in quick and easy to use 20ml sachets is ideal for those requiring an increased accuracy to alkaline testing, particularly suitable for those working in water purification plants, the food industry, aquatics, and Hydroponics, and in any environments where the pH is expected to be alkaline. Hanna Microprocessor pH meters can be calibrated at pH9.18 and pH10.01.
The single dose sachets are really handy with each sealed sachet holding just the right amount of solution. Each time a meter or electrode is calibrated using the Hanna sachets, it is like using a newly opened bottle of solution
Buffer solutions should be stored at 25 C, away from direct sunlight for accurate readings.
To correctly maintain your meter/electrode, we highly recommend use of a Hanna cleaning solution, as well as a buffer, for maximum performance every time. pH4, along with pH7, can also be used as an emergency storage solution.
