COD Chemical Oxygen Demand On-line Water Quality Analyzer
Product Introduction
Adopting the Water Quality — Determination of Chemical Oxygen Demand — Dichromate Method, this instrument ensures accurate and valid monitoring data. It complies with HJ 377-2019, HJ 353-2019, HJ 354-2019, HJ 355-2019 and other standards and has obtained the China Environmental Protection Product Certification. LARSUN is one of the drafting units of the national environmental protection standard Technical Requirements and Test Methods for Automatic On-line CODCr Monitors for Water Quality (HJ 377-2019).
Product Features
• Low reagent consumption: Only 0.2mL reagent for a single test, cutting annual reagent cost by 80%.
• Low waste liquid output: About 3.5mL waste liquid per test, total annual waste liquid around 35L, reducing annual waste liquid treatment cost by 70%.
• High verification accuracy: For large-range measurement of low-concentration standard solutions (1000mg/L range for 25mg/L standard solution), the error is within ±5mg/L.
• Fast measurement: The shortest test time is 25 minutes and the maximum is 30 minutes, complying with the new national standard requirement of one test per hour without data loss.
Application Scenarios
Industrial wastewater, domestic sewage, rainwater and process water.
