FLAME PHOTOMETER - 381E-

FLAME PHOTOMETER - 381E-

Model No: 381

Digital Flame Photometer (2F) with filters Sodium (Na) & Potassium (K) 2½ digit LED display (ppm) along with compressor and other accessories. Detailed specifications are as follow: Note: Double distilled water and LPG gas cylinder is required at the time of demonstration of flame photometer.

Salient Features:

  1. Simple & Easy to Operate
  2. Narrow Band Interference Filters
  3. Accurate Na, K, Ca, & Li Determination
  4. Mixing Chamber Designed For Stable Flame
  5. Concentric Non-Corrosive Nebulizer
  6. Auto Ignition

Construction and working details:

The instruments is supplied in two units viz. Main Unit and Compressor Unit. The Main Unit comprises of digital displays, detector, filters and nebulizer. The compressor unit supplies the compressed air to the main unit


Air at a given pressure is passed into the atomizer. The suction produced by it, draws the sample solution into the nebulizer and is sprayed as fine mist into the flame. The light emitted by the element at the characteristic wavelength is isolated by the narrow band interference filters, which then falls on to the silicon photodiode. After signal conditioning of the photodiode output, it is sent to digital converter and the results are displayed directly in ppm/meq units. The narrow band interference filters are mounted on a rotating disc fitted within the Main Unit. Appropriate filter can be selected by rotating this disc with the thumb. The oil free compressor with regulator maintains a stable airflow.
