Overview
WD9103P total nitrogen meter is a professional water quality analysis instrument of JINGQI brand, which is used for the measurement of total nitrogen content in water. The measurement range is 0.05~ 100mg/L. The instrument adopts High Accuracy Optical inspection system and independent temperature control digestion system to ensure measurement accuracy and stability.
Features
1. Imported high performance, long life (100,000 hours), high luminance Illuminant, with high stability Optical inspection system, high accuracy and good repeability
2. Temperature digestion using independent Digester, PID automatic temperature control, high temperature control accuracy
3. Large-screen LCD display, Chinese character menu operation, convenient and intuitive
4. High temperature digestion and host separation design to avoid the impact of high temperature on the Optical inspection system
5. Can store 10 Linear dispersion and 500 historical records, power failure is not lost
6. Equipped with a USB interface, data can be transferred to a computer
7. With printing function, it supports immediate printing of test records or query records
Principle
The instrument converts the nitrogen-containing compounds in the water sample into nitrate by high temperature digestion, digestion at 125 ℃ for 30 minutes, and then uses the Optical inspection system to measure Absorbance, and calculates the total nitrogen concentration according to the working Linear dispersion.
Applications
Water quality monitoring, environment testing, sewage treatment, industrial wastewater analysis, laboratory testing
Standards
National standards for total nitrogen determination
Steps
1. Prepare water sample and add Reagent
2. Put the sample into the digester and set it to 125 ° C for 30 minutes
3. After the digestion is completed, take out the sample and chill down
4, the sample into the host measurement room
5. Select the corresponding measurement program through the Chinese character menu
6. Read measurement results and record
7. You can choose to print or transfer data via USB
Notice
• Please read the Operation Manual carefully before use
• The digestion temperature can reach up to 180 ° C, pay attention to anti-scalding during operation
Periodically calibrate instruments to ensure measurement accuracy
• Avoid use in strong electromagnetic interference environments
• When the sample concentration exceeds 100mg/L, diluted measurement is required
• Keep the Optical inspection system clean to avoid contamination affecting measurement results
• Ensure stable power supply when storing data
