INSTRAN is a platform of on-line analyzing equipment, which allows measuring one or more physical or chemical parameters in liquid samples, preferably aqueous. On this platform you can set different hardware and software options to achieve an analyzing system that measures in the best conditions, taking into account:

  • The nature of the sample
  • The type of measure
  • The measuring range
  • The cleanings and calibrations required.



  • Orthophosphate reaction with molybdate to form phosphomolybdate complex
  • The phosphomolybdate complex is reduced by the ascorbic acid to form the phosphomolybdenum blue
  • Measurement wavelength : 810 nm


  • Range :  0-10 mg/l
  • Resolution : 0.01 mg/l
  • Calibration : Programmed automatic
  • Consumption of Reagents : Reagent A – 0.7 m/l sample
  • Acid standard : 0.7 ml/sample
  • Analysis Time  : Less than 6 Minutes
