TC-2000B portable COD Tester

I. Introduction 2000B portable COD speed measuring instrument is my company upgraded 200B type COD analyzer based on the transformation of a dedicated on-site determination of COD integrated analyzer. Which COD analyzer with PID automatic adjustment techniques and self-calibration curve, automatic zero adjustment function, enhanced accuracy and stability of the instrument; additional COD analyzer which can be AC-DC dual-use, built-in high-power batteries, built-in micro thermal printer and other characteristics, greatly facilitate the laboratory personnel on-site use. Laboratory testing is widely used in various industries, sewage treatment, universities, environmental monitoring, wastewater treatment and universities, research institutes and other industries. Second, the main features: 1, the unique machine design patterns, digestion and determination of integrated design, more portable measurement; 2, built-in high-power lithium battery DC power supply, field multi-batch experiments; 3, digestion and determination The power supply system separate, non-interfering, reduce outside influence on the results; 4, dual display, LCD backlight display, Chinese operation interface, concise; 5, measurement system uses advanced optics and cold light source, measurement accuracy high, drift and good stability; 6, high-resolution system for the introduction of PID technology regulator, temperature performance, good stability, save energy; 7, the system self-calibration curve built-in measurement functions, auto-zero; 8, built large capacity storage space, can store 600 measurements recorded with time; 9, with RS232 data interface, can be directly connected to the computer and upload test data; 10 built-in mini thermal printer, can print real-time measurement data (optional) ; Easy 11, one suitcase design, machine to carry without reprovision power, easy to use; Third, the main technical indicators: 1, measuring range: 5 ~ 1000 mg / L, 1000 ~ 3000mg / L (> 1000 mg / L dilution assay); 2, the detection principle: rapid digestion spectrophotometry 3, optical stability: less than 0.003A / 30min 4, the measurement error: 5 ~ 50 mg / L, the absolute error ≤ ± 3 mg / L; 50 ~ 200mg / L, the absolute error ≤ ± 6 mg / L; 200 mg / L ~ 3000 mg / L, the relative error ≤ ± 5% (other ranges can be customized) 5, monochromatic wavelength: 610nm 6, digestion temperature: 165 ± 1 ℃ (up to 190 ℃); 7, temperature accuracy: ± 0.5 ℃ 8, T field uniformity: ≤ 2 ℃; 9, temperature error: ± 1 ℃; 10, time error: ≤30S 11, digestion time: ≤ 15 minutes (0-720min free adjustment); 12, digestion number: four water samples (if laboratory expandable up to 25); 13, resistance to chloride interference: [CL-] <1000mg / L; [CL- ] <4000mg / L (optional); 14.
