Overview
The TR-115H water quality permanganate index (CODmn) tester is developed and designed based on the GB11892-89 standard. It uses potassiumhy permanganate to oxidize the reducing inorganic matter and the organic matter that can be oxidized in the water under the heating condition of acid water bath. The sample Absorbance is detected by Spectrophotometric method, species-trophotometry, and the permanganate index concentration value (mg/L) is directly displayed by microcomputer treatment. The matching finished product reagent makes the detection simple, fast, accurate and safe. Appearance of the instrument is small, fast, easy to operate and low cost. It is widely used in emergency monitoring, sewage treatment, chemical industry, wastewater, food, printing and dyeing and other industries. Wastewater detection and R & D institutions, colleges and universities wastewater research.

Principle
Based on the GB11892-89 standard, potassiumhy permanganate oxidation of the reducing inorganic matter and the organic matter that can be oxidized in the water under the heating condition of the acidic water bath, by Spectrophotometric method, spectra-trophotometry detection of the sample at a specific light source wavelength Absorption, and then automatically processed by the microcomputer data, directly display the permanganate index concentration value (mg/L).
Applications
Emergency monitoring, sewage treatment, chemical industry, wastewater, food, printing and dyeing, R & D institutions, colleges and universities
Steps
1. Prepare samples and supporting reagents.
2. Use the digestion Colorimetric integrated tube for water bath heating digestion for 13 minutes.
3. Absorbance detection by instrument Spectrophotometric method, spectra-trophotometry.
4. The microcomputer automatically processes the data and displays the concentration value.
5. Standard or Continuous Measurement mode is optional.
Notice
• Read the help interface for general precautions before operation.
• Ensure that the environment temperature is 5~ 40 ℃, humidity ≤ 85% without condensation.
• Use matching reagents to reduce operating errors.
• Pay attention to the battery level display and charge it in time.
• Data is regularly backed up after storage to prevent accidental loss.
• Customize programs and reagents to adapt to water conditions.
• Optional accessories such as printers need to be configured separately.
