Principle
Nickel ions are first oxidized into tetravalent in ammonia or alkaline solution, and then react with Color developing reagent, chromogenic agent to form a complex, through imported cold light source, narrowband interference technology, Spectrophotometric method, spectra-trophotometry detection sample Absorbance at a specific light source wavelength, and then after microcomputer automatic processing data, directly display the sample nickel concentration value, expressed in mg/L.
Applications
Emergency monitoring, sewage treatment, chemical industry, wastewater, food, printing and dyeing, R & D institutions, colleges and universities
Standards
GB11910-89 "Water quality, determination of nickel, butanedione oxime Spectrophotometric method, spec-trophotometry"
Steps
1. Intelligent operating procedures guide users to easily complete the operation.
2. Select Standard measurement or Continuous Measurement mode.
3. Use digestion Colorimetric tube for determination.
4. Data is read directly and automatically stored.
Notice
• The instrument design is small and easy to carry, but it should be noted that the environment temperature is 5~ 40 ° C and the environment humidity is ≤ 85% without condensation.
• Use matching specialized detection reagents to reduce operating errors.
• Built-in large-capacity rechargeable lithium battery, pay attention to the remaining power display to ensure stable power supply.
• Data storage and power outage protection features prevent data loss, but regular backups are recommended.
Users can develop their own procedures and reagents, but they must adhere to relevant safety regulations.
• The built-in help interface provides general precautions, please consult before operation.
