Overview
TR-205H type total chromium analyzer based on GB7466-87 "water quality, determination of total chromium" improvement, in acidic solution, the sample of trivalent chromium is potassiumhy permanganate oxidation into hexavalent chromium, hexavalent chromium and diphenylcarbonyl dihydrazide reaction to produce purple compounds, through imported cold light source, narrow-band interference technology, Spectrophotometric method, species-trophotometry detection sample at a specific light source wavelength Absorbance, and then after the microcomputer automatic processing data, directly display the total chromium concentration value of the sample, expressed in mg/L. Colorimetric integrated tube detection, so that the detection is simpler and safer. Appearance of the instrument with its small design, rapid detection, simple operation, low cost and other characteristics, widely used in emergency monitoring, sewage treatment, chemical industry, wastewater, food, printing and dyeing industry wastewater detection, can also be applied to R & D institutions, colleges and universities and other institutions of wastewater research use.

Principle
The TR-205H type total chromium tester is based on the reliable certification method - GB7466-87 "Water Quality, Determination of Total Chromium" improvement, in acidic solution, the trivalent chromium of the sample is potassiumhy permanganate oxidation to hexavalent chromium, hexavalent chromium and diphenylcarbonyl dihydrazide react to form a purple compound, through imported cold light source, narrow band interference technology, Spectrophotometric method, spectrophotometry detects the sample at a specific light source wavelength Absorbance, and then after the microcomputer automatically processes the data, the total chromium concentration value of the sample is directly displayed, expressed in mg/L. Colorimetric integrated tube detection is used to make the detection simpler and safer.
Applications
Emergency monitoring, sewage treatment, chemical industry, wastewater, food, printing and dyeing and other industries wastewater testing, R & D institutions, colleges and universities and other institutions of wastewater research
Standards
GB7466-87 "Water quality, determination of total chromium"
Steps
1. Guide to complete the operation according to the intelligent operation program.
2. Select Standard measurement or Continuous Measurement mode.
3. Use digestion Colorimetric tube for detection.
4. Read data or transmit data through a large-screen LCD screen.
Notice
• Built-in help interface to explain the general precautions of the user's detection process.
The digestion environment is 125 ℃, 30 minutes, pay attention to safe operation.
The measurement time is about 45 to 55 minutes, so be patient.
Before use, ensure that the environment temperature is 5~ 40 ℃, humidity ≤ 85% without condensation.
• Regularly check the remaining battery power to ensure the normal power supply of the instrument.
• Optional Bluetooth printer for data printing, pay attention to compatibility.
