Multi-element Flame Photometry Analyzer

Multi-element Flame Photometry Analyzer

  • Product Number:LD-41
  • Product Difference:Analytical instruments for secondary fitting of K, Na, Li, and Ba

Product Introduction

The Multi-Element Flame Photometer is a newly designed instrument. It features a compact size, user-friendly operation, and stable reliability. The entire series comes standard with an ion detection flame failure device, ensuring safety and dependability. It is widely used in the analysis and determination of agricultural fertilizers, soils, cement, ceramics, and other industries, as well as in the silicate industry and pathological research in medical and health fields. The flame photometer utilizes liquefied petroleum gas as its fuel.

Product Features

  • Features direct concentration readout for five elements: K, Na, Li, Ca, and Ba, capable of simultaneously displaying up to three elements in any combination.

  • Equipped with an RS232 interface for connecting to printers and PC software.

  • Includes automatic correlation coefficient calculation, preset flame size selection, standard curve storage, and single-point calibration functions.

  • Equipped with flame failure protection and a moisture separator.

  • Features menu-driven keyboard operation.
