Flame Photometer

  • Product Number:LD-21
  • Product Difference:K, Na Multi-Line Calibration Analytical Instrument

Product Introduction

Flame photometers are analytical instruments designed and manufactured based on the fundamental principles of emission spectroscopy. They are widely used in industries such as agricultural fertilizers, soil, cement, and ceramics, as well as in the analysis and determination of silicate industries and pathological research in medical and health fields. Flame photometers utilize liquefied petroleum gas as fuel.

Product Features
