SPECTRO COLORS METER - PLATE AND PROGRAMMED SYSTEM
Producer: AVT

This project shows how modern electronics help a chemist. The device is used to measure the concentrations of colored substances or those that have colored reaction products. The phenomenon of selective absorption (absorption) of radiation with a strictly defined wavelength was used. Its source in the present glass is the LED diode. In comparison to other sources, the spectrocolorimeter using it will have lower sensitivity and a smaller range of the linear relationship between absorption and concentration.

The device is especially recommended for inquisitive chemists-electronics

Selected parameters:

  • source of radiation beam - LED diode
  • the ability to change the LED (color) depending on the substance being tested
  • control and measurement - ATmega8 microcontroller
  • reading - LCD display
  • zeroing function
  • additional function - UV absorption test for sunglasses
  • power supply - 9-12Vdc
  • a printed circuit board, programmed layout and documentation in the set
