INSTRAN Boron Analyzer from Spain is designed to handle all kind of samples ranging from drinking water to waste water application. It incorporates laboratory measuring technique (Colorimetric) into online analyzer with self-cleaning in each analysis to ensure the measurement is in high precision.

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

INSTRAN Boron Analyser

Measuring Principle: Colorimetric

  • The sample is adjusted to pH between 5 and 6 with the buffer reagent,
  • Addition of Azomethine-H & Ascorbic acid, they reacts with Boron giving a green-yellow color that is measured at 420nm.
  • The method is accurate and sensitive and the range is linear up to 2 ppm and higher ranges can be obtained diluting the sample.


  • Reliable, Exact and Fully Automatic Analysis
  • Self Cleaning After Each Measurement
  • Very low maintenance & operating cost
  • Low reagent consumption
  • Multi-Color Graphic Display
  • Tested without Remarkable Interferences


  • Drinking Water
  • Process Water
  • Ultra Pure Water System
  • Predictive Tool of end of ION Exchange System Operating Cycle
  • De-ionized Water leakage of weak acids, weak bases, silica and colloidal silica particles
