Overview
TR-408H COD ammonia nitrogen total phosphorus total nitrogen turbidity tester is a water quality testing instrument developed and designed by TONGAO based on HJ/T399-2007, HJ535-2009, GB11893, US EPA certification method and GB13200-91 and other standards. The instrument adopts imported cold light source and narrow band interference technology. Absorbance of samples is detected by Spectrophotometric method, spectrophotometry, and concentration value is directly displayed after microcomputer treatment, expressed in mg/L or degrees. It adopts digestion Colorimetric integrated tube design, which has the characteristics of small and portable, fast detection, simple operation and low cost. It is widely used in emergency monitoring, sewage treatment, chemical industry, food, printing and dyeing industry wastewater detection and scientific research and teaching institutions.

Notice
• Please read the operating instructions carefully before use
• Ensure that the instrument is used in an environment temperature of 5~ 40 ° C
• Environment humidity should be ≤ 85% non-condensing
• Use matching specialized reagents to ensure detection accuracy
• Pay attention to digestion temperature and time parameters: COD digestion 165 ℃ 15min, total phosphorus and total nitrogen digestion 125 ℃ 30min
• Regularly check the battery power to ensure sufficient power supply
• After the data is stored over 4000 pieces, it needs to be exported in time
• Clean and maintain the instrument in time after use
• Non-professionals should not disassemble and repair by themselves
