Meters

 

JIS Z 8802 classifies the types of pH meters in terms of repeatability, as follows. The JIS classification of the product is stated in the product specifications for your information.

 

JIS Classification	Description	Purpose
0	Repeatability within ±0.005 pH for the pH measurement of a standard solution	High-accuracy measurement
Ⅰ	Repeatability within ±0.02 pH for the pH measurement of a standard solution	Accurate measurement
Ⅱ	Repeatability within ±0.05 pH for the pH measurement of a standard solution	Normal measurement
Ⅲ	Repeatability within ±0.1 pH for the pH measurement of a standard solution	Simple measurement

We have a wide range of products lined up for different purposes, such as pH standard measurement/field measurement devices, a super-accurate meter with a resolution of 0.001 pH, and multi-sample measurement devices with connection to a turntable, etc. All of our pH meters have met quality control standards, passing double/triple inspections, and are provided with qualifications for pH measurement.
