Pump Calibration Standard for Sulfur Dioxide Mini Titrator – HI84500-55

The HI84500-55 is a 120 mL bottle of pump calibration standard that is used to calibrate the dosing system of the HI84500 Sulfur Dioxide Mini Titrator for Wine Analysis.A calibrated dosing pump allows for the accurate determination of the amount of titrant used when performing a titration. The amount of volume dosed along with the concentration of the titrant is used by the pre-programmed formula within the HI84500 in determining the exact concentration of sulfur dioxide. The pump calibration procedure should be performed anytime the titrant or ORP electrode is replaced.

  • Standardized solution
  • Clearly marked expiration date and lot number
  • Air tight bottle with tamper-proof seal

Analysis of sulfur dioxide in wine, as performed on the HI84500 mini titrator, utilizes a simple sample preparation, a high quality titrant dosing pump, potentiometric endpoint detector, and automatic computations. To maintain the high precision of the titrator, a simple pump calibration procedure is performed with HI84500-55 pump calibration solution. The pump calibration procedure involves the analysis of a known volume of a known solution. The pump calibration procedure should be performed anytime the titrant, syringe, tubing or ORP electrode is replaced. Periodic calibrations should be performed in order to accurately determine the free and total sulfur dioxide levels in wine.The HI84500 determines the free and total sulfur dioxide concentration in wine using the Ripper method. Excess iodide is added to the wine sample and reacts with the iodate titrant to produce iodine:IO3– + 5I– + 6H+ → 3I2 + 3H2OThe iodine produced reacts with sulfur dioxide in the wine according to the redox reaction below:H2SO3 + I2 → H2SO4 + 2HIReplacement reagents required to operate the HI84500 include:

Low Range – 1.0 to 40.0 ppm of SO2High Range – 30 to 400 ppm of SO2

    Conductivity (EC) Controller (0.0 - 199.9 µS/cm) - BL983320-1 | 115/230VAC

    734.00 AED
    The BL983320 is a compact, panel mounted, process controller for measuring electrolytic conductivity (EC) of a process stream that is within the 0.0 to 199.9 µS/cm range. The device features a large LCD with protective cover. Users may choose from automatic or manual dosing modes. When in automatic mode the dry contact relay is activated when a reading is above the set point. The relay can be used to activate a solenoid that switches from one DI (deionized) tank to another or to open a valve that will allow lower EC water to flow into a tank being monitored in order to lower its EC. The BL983320 can also be used to monitor the quality of water produced from ion exchange, reverse osmosis (RO) or distillation. Multicolor LED Indicator LED changes color based on status. Fire Retardant Casing For additional safety the controllers outer case is made of fire resistant plastic. Splash Resistant Cover A clear plastic cover protects the face panel from dirt and liquids.
