JCSS pH Standard Solution

pH is a unit necessary to know the degree of acidity and alkalinity of a solution. It represents the hydrogen ion activity in the solution. Because the hydrogen ion activity in the solution cannot be directly measured, the pH is measured by comparing with the pH of one aqueous solution. Therefore, clear pH definitions and standards are important, so the International Organization for Standardization (ISO) and the Japanese Industrial Standards (JIS) specify the measurement method for pH ¹⁾.

As a JCSS accredited laboratory of inorganic standard solutions (ion standard solutions, metal standard solutions), organic standard solutions and pH standard solutions, FUJIFILM Wako fundamentally supports the reliability of various test and calibration results by ensuring traceability to international measuring standards.
The JCSS standard solution is a standard solution accompanied by a calibration certificate of with a JCSS certification symbol. FUJIFILM Wako was accredited as a certified international MRA certified provider by IAJapan (an accreditation center of National Institute of Technology and Evaluation) which is a member of the MRA (Mutual Recognition Agreement) of ILAC (International Laboratory Accreditation Cooperation) and APAC (Asia Pacific Accreditation Cooperation), and issues calibration certificates with the JCSS certification symbol with ILAC MRA in proof of this certification. The results of the calibration value described in this JCSS certificate are internationally acceptable through the MRA of ILAC/APAC.

JCSS standard solutions are available in various pH ranges. Our standard solutions enable more accurate pH measurement.
