HI6004 HANNA BUFFER SOLUTION น้ำยามาตรฐาน pH4.010

Description

HI6004 is a premium quality pH 4.010 Millesimal buffer solution, National Institute of Standards and Technology (NIST) traceable and supplied with a Certificate of Analysis.
One of the most commonly used buffer solutions, it is extremely stable and represents the mid-way point in the acid range of the pH scale - ideal for those requiring an accurate acid reading, particularly those working in water purification plants, the food industry, and wherever the pH is expected to be acidic.
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.
Buffer solutions are produced to a premium quality for customers who require a greater resolution of 0.001 for pH measurements. Accuracy can be guaranteed at +/- 0.002 @ 25◦C.
