ISE Fluoride Measurement with TISAB and SKA Method

INSTRAN FLUORIDETrace Analyzer from Spain is designed to handle all kind of samples ranging from drinking water to waste water and even for sea water application. It incorporates laboratory measuring technique into online analyzer with self-calibration and self-cleaning in each analysis to ensure the measurement is in high precision.

The unique design of INSTRAN FLUORIDETrace analyzer with syringe volume-controlled method ensures syringe will never contact with samples or reagents and thus prolong the shelf life of the syringe. The analyzer requires very little maintenance and low reagents consumption but yet powerful and high in accuracy.


Measuring Principle: Selective Electrode-ASTM D 1246 – EPA 60 FR

  • Measurement Range: 0-5ppm, 0-10ppm , 0-100ppm as F-, “Adjustable Higher Concentration up to 18000ppm as F with Internal Dilution”
  • Measure by Single Known Additional (SKA) Method
  • Accuracy: +/- 2% FS

Benefits and Features:

  • Precise Volume controlled of Sample and Reagents by Syringe Dosing System ensuring excellent accuracy and repeatability
  • Self Cleaning after each measurement
