Water Quality Tester LS310

is an advanced and portable instrument designed to provide a comprehensive assessment of drinking water quality.

Utilizing a combination of ultraviolet absorbance and conductance measurement methods, it simultaneously evaluates six crucial water quality parameters:

• Chemical Oxygen Demand (COD),
• Total Organic Carbon (TOC),
• Ultraviolet Absorption Value (UV275),
• Total Dissolved Solids (TDS),
• Electrical Conductivity (EC),
• Temperature.

This innovative device goes beyond simple measurements with its intelligent scoring function, providing an immediate and clear indication of water quality based on Chinese drinking water standards. The intuitive LCD backlight changes color (blue, green, yellow, red) to correspond with four distinct water quality levels: Fine, Good, Average, and Poor, making it easy to interpret results at a glance.

Key Features:

• Multi-Parameter Analysis: Measures 6 essential water quality indicators (COD, TOC, UV275, TDS, EC, Temperature) simultaneously, offering a holistic view of water purity without the need for reagents.
• Intelligent Water Quality Scoring: Provides a quick and easy-to-understand water quality assessment with a 4-level scoring system (Fine, Good, Average, Poor) and corresponding color-coded LCD backlight.
• UV275 for Residual Chlorine Indication: The UV275 parameter indirectly reflects the residual chlorine content in water, with higher values indicating greater chlorine presence.
• Reflects Organic Pollution & Contaminants
• COD & TOC: Indicators of organic pollution, including bacteria, viruses, and microorganisms.
• UV275: Reflects macromolecular organic compounds, aromatic compounds, and can indirectly indicate pesticide residues.
• TDS: Represents the total amount of dissolved ionic molecules and compounds, such as calcium chloride, sodium chloride, magnesium sulfate, and potassium sulfide.
• High Accuracy & Resolution: Delivers precise measurements across various ranges with excellent resolution for each parameter.
• Compact & Portable Pen Design: Lightweight (approx. 68g) and pocket-sized (157x37x14mm) for easy carrying and on-the-go testing.
• Sensitive & Waterproof Probe: Equipped with highly sensitive probes and a high-precision temperature sensor for accurate readings. The probe is IP67 waterproof, ensuring durability and reliability.
• User-Friendly Operation: Features a simple one-button measurement for effortless water quality assessment.
• Wide Application: Ideal for testing various drinking water sources, including tap water, purified water, bottled water, groundwater, and surface water (non-sewage).
