Microprocessor Based Flame Photometer
Click to Enlarge

Microprocessor Based Flame Photometer (AVI-575)

An ideal instrument for the determination od Sodium Potassium, Calcium and Lithium. it uses the latest Microcontroller technology and advanced engineering techniques so as to give enhanced accuracy and reproducibility. The System has 3 point calibration facility using curve fitting software. It has soft touch membrane keys for ease of operation. The solution is aspirated through an atomiser. Air, sample and the fuel are mixed in the mixing chamber which is then sprayed as a very fine mist into the flame. The color of the flame is changed depending upon the concentration of elements present. Radiations from the flame passes through the sensing system and specific narrow band interference filter which permits only the characteristic radiation to pass to the photodetector. The output of the photo-detector is then processed by the microcontroller and the final results are displayed on the digital display.
