1. Product Introduction
The SS03A portable multi-parameter water quality
meter is an electrode-based water quality analysis instrument that uses fully
digital electrode detection to detect water quality, water temperature, orp, and
pH parameters. The instrument is equipped with a self-developed ftiot operating
system, which is simple to operate, stable in performance, accurate in
measurement, and has a wide detection range. It has a built-in high-capacity
rechargeable lithium battery, which is convenient for users to conduct water
quality testing at any time in the field or laboratory.
