86311 Multi-Parameter Water Quality Tester

The 86311 is a multi-parameter water quality tester designed for household drinking water including tap water, purified water, and groundwater. It is also suitable for seawater and aquaculture salinity testing.

The device uses UV absorbance to measure COD, TOC and UV275, and uses electrical conductivity to calculate TDS, electrical conductivity (EC), salinity (SAL), general hardness (GH) and specific gravity (S.G.). The 86311 provides intelligent water-quality scoring with backlight colors indicating four grades: Excellent, Good, Fair, and Poor. It features automatic temperature compensation to ensure consistent repeatability and accuracy across different environments.

Key Features

Fast testing for household drinking water: Simple operation—just press once to quickly determine whether water meets national drinking-water safety standards.
Smart scoring system for clear water-quality assessment: Display automatically changes backlight color according to water-quality rating: Excellent, Good, Average, or Poor.
Salinity, General Hardness & Specific Gravity measurement: Accurately calculates salinity, general hardness, and specific gravity through electrical conductivity measurement.
Simultaneous measurement of 9 water-quality parameters: Measures SAL, GH, S.G., COD, TOC, TDS, UV275, EC, and Temperature for comprehensive water evaluation.
Multi-parameter scoring to avoid misjudgment: Evaluates multiple parameters for more accurate and comprehensive rating of mineral and drinking water.
Pen-style design, compact and portable: Small, lightweight design for easy carrying and on-the-go use.
Temperature compensation for accurate, stable results: Automatic temperature compensation ensures repeatability and accuracy with long calibration intervals.
Indirect indication of residual chlorine: UV275 readings can indirectly reflect residual chlorine levels.
