High-specification pH meter
PE-31EFP

PE-31EFP is a model with four-point warning and 　time-sharing proportions.

This is an easy-to-use model with a detailed set of settings that can respond to a variety of requests and an error display based on the self-diagnosis function.

Advantages

・One-touch calibration.

・Automatically judges whether the electrode characteristics are good or bad.

・Five types of temperature compensation elements are supported.

・Combined with lead-free pH electrodes, environmentally friendly measurements are realized.

・High-end type with 4-point alarm and time-division proportional (PE-31EFP).

・External input can be used to interlock with the washer (PE-31EFP).

Applications

・PH neutralization and oxidation/reduction treatment of wastewater from the chemical industry

・To the incorporation of each process unit

・For pH measurement management such as hydroponic cultivation

・For measuring and managing the pH of cleaning wastewater

・For pH measurement management of experimental wastewater
