Automatic Total Nitrogen Analyzer Model TNC - 250

Automatic Total Nitrogen Model TNC - 250 - As the total nitrogen measurement process of this analyzer is adopted with contact thermal decomposition method for decomposition and with chemiluminescence for detecting method, reagents are not required for the measurement - “ Help” function ( software) is employed at all of touch panel screen to give quick reference at each operation stage, thereby, operability and maintenance activity are improved - Data storage capacity becomes greater because of the adoption of CF card ( Data storage capacity is for approx. five years of operation) - This analyzer is applicable to the sample containing sea water Specification : Name of product : Total Nitrogen Automatic Analyzer Model : TNC-250 Measuring object : Total Nitrogen in water ( for process surveillance and effluent monitoring) Measuring method : Chemiluminescence Measuring range : Optionally selectable among ranges 0~ 20, 0~ 50, 0~ 100, 0~ 500, 0~ 1000mgN/ L ( No dilution for 0~ 20mg/ L range) Repeatability : Within + / -3% F.S. ( at span calibration solution) Within + / -4% F.S. in case that dilution is used Measuring cycle : 5 min. ~ 120min. ( optionally settable among 5, 6, 10, 12, 15, 20, 30, 60, 120) Measurement path : 1 flow path, 2 flow paths Display system : Touch-screen system ( “ Help” menu is appeared at each screen) Recording method : Compact flash memory is integrated, printer having automatic rewinding function Calibration method : Manual calibration or automatic calibration by calibration solution Calibration sol. : Potassium nitrate Consumption of Calibration Sol. : 500mL/ calibration ( in case of no dilution and every 5 times of measurement) Analog output signal : 4~ 20mADC measurement value of one flow path 2 channels, Load resistance 600W or less
