Product Description

Product Introduction

Product Introduction

Brand: ERUN
Name: PH Online Water Quality Monitoring Instrument
Model: ERUN-SZ4-A-B7
Parameter: PH(Electrode method)

The ERUN-SZ4-A-B7A water quality pH online detector sensor uses high-performance industrial online electrodes, which can work stably for a long time. The built-in temperature sensor automatically performs temperature compensation, and can be easily networked and integrated into the system without a controller. It is widely used in water quality treatment, hydrological monitoring, wastewater treatment, swimming pools, aquaculture water and other fields for continuous and real-time water quality pH detection.
