AH-151 – Automatic calibration function pH meter

The consumption of calibration solution is 1/5 or less as compared with our existing products*, which contributes to a reduction in running costs.


The pH meter AH-151 with automatic calibration function performs pH measurement by automatically cleaning the electrode with cleaning solution and performing calibration with standard solution, making it possible to drastically reduce maintenance work. In addition, by spraying the calibration solution, the consumption of calibration solution has been reduced. The spray amount of the cleaning solution can also be adjusted according to the condition of contamination, which contributes to cost reductions. With periodic cleaning and calibration, stable and highly reliable pH measurements are possible.
