The HI84500 is a fast, accurate, and affordable automatic mini titrator designed for testing free or total sulfur dioxide (SO2) levels in wine, juice, and must. Based on the Ripper Method, this mini titrator uses an optimized, preprogrammed method of analysis with a powerful algorithm that determines the completion of the titration reaction by the use of a specialized ORP electrode.
The HI84500 incorporates a precision piston style dosing pump that adjusts the volume of dosing dynamically based on the voltage changed. This dosing system reduces the amount of time required for the titration while providing for a highly accurate determination of the amount of titrant used.
This mini titrator is supplied complete with all the materials necessary to perform low and high range measurement of SO2. All chemicals are premixed and prepackaged including standardized titrants, reagents and pump calibration solution. There is no need for volumetric glassware or analytical balances.
Features:
- Application-Specific ORP Electrode The HI84500 is supplied with the HI3148B ORP electrode featuring CPS technology to prevent the clogging of the reference junction. Conventional electrodes may clog quickly in samples such as wine that have a high suspended solids content. By design, the HI3148B ORP electrode utilizes a ground glass/PTFE sleeve junction which controls a steady, predictable flow of electrolyte solution, keeping the junction open. The hydrophobic properties of PTFE repel wetness and coatings.
- Piston Driven Dosing Pump The heart of the HI84500 is the piston driven burette pump. This type of dosing system uses a motor in which each dose is very precisely controlled and the volume dispensed is accurately determined. The piston driven burette is controlled dynamically so that the volume of titrant being dosed is automatically adjusted based on a voltage response of the previous dose. This type of dosing speeds up the titration process by allowing for more titrant to be dosed at the start of the titration and then very small doses as the endpoint is reached.
- Automatic Stirrer The built-in stirrer is automatically maintained at a speed of 700 rpm, regardless of the viscosity of the solution being titrated.
