Introduction

Brand: Erun Environmental protection

Name: Portable water hardness tester

Model: ERUN-80-H2

Parameter: Hardness (measuring method: Acid chrome blue K method)

ERUN-80-H2, a portable water hardness tester developed and produced by Erun Environmental Protection, is a new type of intelligent portable water quality analysis instrument, which uses a monochrome cold light source and uses a microcomputer to automatically process data and directly display the hardness concentration value of the water sample. It is widely used in the determination of drinking water, surface water, surface water, sewage and industrial wastewater.
