KORBI Co., Ltd. products

HACA-4000 is a measuring instrument that automates potassium permanganate method of water pollution test method. The potassium permanganate method measures the COD by adding a certain amount of oxidizing agent (potassium permanganate) to the sample, heating it, converting the amount of potassium permanganate consumed in the oxidative decomposition of the organic matter to the corresponding amount of oxygen consumed. At this time, the appropriate amount is calculated by recognizing the rising point of the ORP value by the addition of potassium permanganate as the proper end point. The HACA-4000 is a new product from KORBI that not only improves performance by applying patented technology and preliminary measurement logic, but also has sophisticated design and user-friendliness.

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.

HATP-4000 is a measuring instrument that automates the ultraviolet / visible spectroscopy (thermal oxidation method) of the water pollution test method. In the pretreatment step, potassium persulfate is added to the sample and heated at 120°C for 30minutes to oxidize and decompose the phosphorus compound into phosphate form. Oxidized phosphorus phosphate is colored with molybdenum blue and absorbance is measured. The absorbance of total phosphorus is measured at 880nm which is the maximum absorption wavelength of phosphorus phosphorus. HATP-4000 is KORBI’s new product which not only improved efficiency by adopting patented technology and our own developed oxidation tank, but also has sophisticated design and user’s convenience.

HATN-3000 is an automatic measuring instrument for ultraviolet / visible spectroscopy of water pollution test method. In the pretreatment step, alkaline potassium persulfate is injected into the sample, heated at 90°C for 15 minutes, and irradiated with UV light to 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-3000 is a new product of KORBI which not only shortens measuring time by adopting patented technology and newly-designed oxidation reaction chamber, but also has sophisticated design and user convenience.

The HATP-3000 is an automatic measuring instrument for ultraviolet/visible spectroscopy of the water pollution test method. In the pretreatment step, potassium persulfate is injected into the sample, heated at 90°C for 15minutes, and irradiated with UV light to oxidize and decompose the phosphorus compound into phosphate. Oxidized phosphorus phosphate is colored with molybdenum blue and absorbance is measured. The absorbance of total phosphorus is measured at 880nm which is the maximum absorption wavelength of phosphorus phosphorus, and the wavelength can be selectively measured at 710nm according to the sample water condition at the measurement site. HATP-3000 is a new product of KORBI which not only shortens measuring time by adopting patented technology and its own oxidation reaction tank, but also has sophisticated design and user convenience.
