1、IIREFERENCE METHODA laboratory reference method for ozone precise quantification must be available at each plant, in order to :? Calibrate the Prominent on-line monitoring system 匹 check the correct functioning of the Orbisphere on-line monitoring system? Control the ozonation process functioning (o
2、zone injection, losses and decomposition kinetic)? Check the correct functioning of the routine monitoring method for the finished productsThe standard method for measuring residual ozone is based on decolorization of indigo trisulfonate measured at 600 nm wavelength.A simple laboratory test kit ada
3、pted from this method, was developed by HACH Company. This consists of a spectrophotometer and vacuum ampoules with pre-dosed amount of reagent (AccuVac).It will guarantee the best accuracy, because :? No loss of ozone when the ampoule is f川ed.? Stability of the color developped.? Accurate color rea

6、ed, waterproof, suitable for extended field work or quick, on-the-spot process monitoring in any conditions, day or night. The instrument uses an LED light source and silicon photodiode detector operating at a fixed wavelength of 600i2 nm, with a filterbandwidth of 15 nm. It is powered by 4 included
7、 AAA alkaline batteries sufficient for approximately 2000 tests. Each instrument comes as a complete kit, with reagent set, manual and complete step-by-step instructions, and sturdy carrying case.Verification & Calibration : Pocket Colorimeter II allows user calibrations, giving the ability to perfo
8、rm a standard adjust. This is done with an ozone standard kit.REAGENT DESCRIPTION :The test kit is made up of vacuum glass ampoules, called AccuVac, with pre-dosed reagent.The reagent is indigo trisulfonate. The ampoule top is broken into the sample and water is automatically sucked up. This avoids any loss of ozone.
