A single immersion test reports nine parameters: COD, TOC, UV275, TDS, electrical conductivity, salinity, general hardness, specific gravity and temperature.\u003c\/p\u003e\n\n\u003cp\u003eUV absorbance is used for COD, TOC and UV275 analysis, while conductivity measurement supports the calculated TDS, EC, salinity, general hardness and specific-gravity results. The color display groups the overall water-quality score into four easy-to-read grades for faster screening.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNine water-quality parameters:\u003c\/strong\u003e Consolidates organic-content, dissolved-solids, conductivity, salinity, hardness, density and temperature information in one portable instrument.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCOD and TOC range up to 100mg\/L:\u003c\/strong\u003e Supports rapid evaluation of organic contamination in suitable water samples.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTDS up to 2000ppm and EC up to 4000µS\/cm:\u003c\/strong\u003e Provides practical insight into dissolved material and ionic content.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSalinity, hardness and specific gravity:\u003c\/strong\u003e Extends the instrument beyond a conventional TDS pen for seawater and aquaculture checks.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFour-grade smart scoring:\u003c\/strong\u003e Color-coded Excellent, Good, Average and Poor results simplify initial water-quality assessment.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAutomatic temperature compensation:\u003c\/strong\u003e Improves measurement stability across changing sample environments.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompact color display:\u003c\/strong\u003e The 1.14-inch 240×135 TFT screen presents results clearly in a portable pen-style body.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIP67 probe:\u003c\/strong\u003e Supports routine immersion measurements in field and facility environments.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLightweight operation:\u003c\/strong\u003e The approximately68g tester runs on two readily available AAA alkaline batteries.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eTap, purified, bottled and groundwater screening\u003c\/li\u003e\n  \u003cli\u003eNon-sewage surface-water checks\u003c\/li\u003e\n  \u003cli\u003eSeawater salinity and specific-gravity measurement\u003c\/li\u003e\n  \u003cli\u003eAquaculture water monitoring\u003c\/li\u003e\n  \u003cli\u003ePortable multi-parameter water-quality assessment\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy Choose the Linshang LS311?\u003c\/h3\u003e\n\u003cp\u003eThe LS311 combines measurements that would otherwise require separate TDS, conductivity, salinity and organic-content instruments.
