OL 3120 Fully Automatic COD Intelligent Analyzer Introduction: The OL3120 fully automatic COD intelligent analyzer is based on the determination of chemical oxygen demand using the dichromate method according to HJ 828-2017. Add a known amount of potassium dichromate solution to the water sample, and use silver salt as a catalyst in a strong acid medium. After boiling and refluxing, use ferrous sulfate as an indicator to titrate the unreduced potassium dichromate in the water sample. Calculate the mass concentration of oxygen consumed from the amount of potassium dichromate consumed. Determination of Chemical Oxygen Demand in Surface Water, Domestic Sewage, and Industrial Wastewater. This instrument is a fully automatic and intelligent instrument designed and developed based on the principles of traditional manual experimental methods. Automatically complete operations such as identification, titration, measurement, reagent injection, digestion, emptying, dilution, measurement, collection, etc; More intelligent recognition of excess range and automatic dilution function; Equipped with a waste liquid recovery device, there is no need to equip a fume hood, and the entire experimental process does not require human intervention; Widely applicable, more efficient, lower loss, more stable, and more precise. Efficient detection capability, safety protection, and stay away from toxicity. characteristic: 1. The specialized automatic intelligent fast and slow titration system significantly improves detection efficiency and rejects long waiting times for test results. Point-to-point rapid cooling system 2. Ensure that each condenser tube reaches the cooling point, which not only improves analysis efficiency but also ensures accurate and reliable detection data. 3. If the number of water samples to be processed exceeds the digestion level, there is no need for manual intervention between digestion batches. 4. Intelligent sample and reagent addition system, automatic digestion, achieving calibration during automatic digestion, can greatly improve work efficiency and shorten time 5. Intelligent recognition, over range dilution, and automatic conversion between high and low ranges. 6. Automatic cleaning of pipelines, automatic cleaning of digestion bottles and titration bottles, with adjustable cleaning times. 7. Automatic cleaning and digestion cup, no need to disassemble, avoiding manual involvement in introducing pollution. 8. The entire process is enclosed to prevent environmental pollution and avoid cross contamination. 9. Optional high chlorine module for fully automatic measurement of high chlorine water samples Technical parameters: Sample size: 30-100 digits optional Dissolve digits: 20 digits Instrument structure: Adopting a fully enclosed design to prevent environmental pollution Injection method: assembly line, automatic measurement of 10 milliliters Addition method: syringe, metering pump Cooling method: air cooling Endpoint determination: Intelligent determination of titration endpoint based on color, fully compliant with standard methods Dissolving temperature: intelligent micro boiling system, no need for manual adjustment Automatic report: Automatically send detection reports, export data directly to Excel or PDF, can be integrated with LIMS, and upload detection data in real time Automatic cleaning: Automatic cleaning of pipelines, digestion bottles, and titration bottles, with adjustable cleaning times Accuracy: The measured values of the quality control samples are all within the qualified range Ultra high sample: automatic dilution Titration system: dual core High low conversion: automatic dilution beyond the range, automatic switching between high and low ranges Operation method: Touch screen computer, one click operation to complete measurement
