Description

The HI84502-55 is a 120 mL bottle of pump calibration standard that is used to calibrate the dosing system of the HI84502 TItratable Acidity Mini Titrator for Wine Analysis. With 4 mL of solution required per pump calibration, there is enough standard to perform approximately 30 pump calibrations. 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 HI84502 in determining the exact titratable acidity. The pump calibration procedure should be performed anytime the titrant or pH electrode is replaced. Routine calibration is recommended to ensure the highest of accuracy when performing a titration.
  • Pre-measured solution
  • Clearly marked expiration date and lot number
  • Air tight bottle with tamper-proof seal to ensure quality
Analysis of titratable acidity in wine, as performed on the HI84502 mini titrator, utilizes a simple sample preparation, a high-quality titrant dosing pump, potentiometric endpoint detector, and automatic computations. As the titrant comes pre-standardized, it is important to determine the amount of titrant delivered by the dosing pump by performing a pump calibration procedure. In this procedure, the analysis of a known volume of a known solution is titrated with to the pH 8.2 endpoint determined by the HI1048B pH electrode. The same pump calibration solution is used for both the low and high ranges. The pump calibration procedure should be performed anytime the titrant, syringe, tubing or pH electrode is replaced. It is recommended to do a pump calibration every time a new set of titrations are to be performed.
 
Replacement reagents required to operate the HI84502 include:
 

Low Range - 0.1 to 5.0 g/L of tartaric acid


High Range - 4.0 to 25.0 g/L of tartaric acid
