Krüss offers the Flame Photometer model FP8800 for simple, precise, cost-effective measurement in industrial applications. It is Ideal for concentrated alkaline elements. In aqueous solutions, the unit will deliver a rate of around 300 samples per hour. It measures up to three alkaline elements simultaneously

  • Economic, robust, safe and long-lasting measuring instrument.
  • Simple, precise and cost-efficient measuring method for the simultaneous determination of alkali and alkaline earth element concentrations in aqueous samples.
  • Precision ≤ 0.5 % CV with 10 mg/l Na-, K-, Li-, Ca-standard solution.
  • Touch Screen , 800 x 600 pixels. Complete user management, SQL data base, export of measured data to Excel.
  • Option 1: automatic measuring connected with the sampler and sample dilution (FP8801).
  • Option 2: PROFIBUS DP interface and remote module for usage in process control (FP8800).
  • The FP8800 has 4 independent measuring channels and an additional separate channel for the monitoring of the flame.
  • The 4 measuring channels can be equipped with the appropriate optical filters.
  • The FP8800 does not require a spectral reference line, although measurement operation can be carried out either with or without a reference element.
