HATN-4000
Online TN Analyzer
HATN-4000 is a measuring instrument that automates the ultraviolet / visible spectroscopy (thermal oxidation method) of the water pollution test method. In the pretreatment step, alkaline potassium persulfate is injected into the sample, and the sample is heated at 120°C for 30 minutes to oxidize and decompose organic and inorganic nitrogen compounds into nitrate ions. After cooling, hydrochloric acid is added to lower the acidity, and ultraviolet absorbance is measured at 220nm to measure total nitrogen. At this time, it is possible to measure more accurately by measuring the absorbance of the disturbance factor at 275nm to calibrate the measurement value. HATN-4000 not only improves efficiency by adopting patented technology and newly-developed oxidation reaction chamber, it is KORBI’s new product with sophisticated design and user’s convenience.

Application of the latest revised water quality pollution process testing standards
- Application of revised communication standards for continuous automatic measuring devices for water quality pollution process testing (National Institute of Environmental Research Notice No. 2020-18)
Adoption of an oxidation reactor with improved efficiency through self-development
- Adoption of a self-developed oxidation reactor capable of implementing the high temperature/high pressure environment suggested by the water quality pollution process test standards.
- By reducing the oxidation reactor capacity (by half), efficiency is increased and the amount of reagents and samples used is reduced compared to conventional products.
Application of our unique multi-channel valve system for quantitative distribution of samples and reagents.
- Ensures accurate distribution of samples and reagents using our patented 7-port valve control technology.
- Improved metering precision and accuracy through the use of high-performance micro-pulse pumps
Built-in user-centric operating program with enhanced security features
- User-centric, intuitive GUI screen layout
- Strengthening software security through KORBI electronic certification
- Built-in data manipulation prevention function (including file deletion prevention function)
- Built-in automatic correction and self-diagnosis functions
Built-in various features to enhance user convenience
- Two-door system allows front-end work, improving on-site operational convenience.
- Equipped with a valve for automatic supply of distilled water or tap water inside the reagent compartment (optional)
- Built-in separate discharge function for hazardous waste liquid and general waste liquid (optional)
Building a diverse product lineup with sophisticated designs
- New, luxurious design features, including sensory colors and mirrored viewing windows.
- Expanding the product lineup to provide a diverse range of HS-KOREA products
