This is a simple, fast and affordable mini titrator designed for testing total acidity levels in wine. Based on an acid-base titration method, this mini titrator uses a preprogrammed method of analysis with a powerful algorithm that determines the completion of the titration reaction by use of a specialized wine pH electrode. This mini titrator is supplied complete with all the materials necessary to perform low and high range measurements of total acidity. All chemicals are premixed and prepackaged including standardized titrants, reagents and pump calibration solution. There is no need for volumetric glassware or analytical balances.
Application-Specific pH Electrode
The HA-HI84502 is supplied with a glass body pH electrode featuring CPS™technology to prevent the clogging of the reference junction. Conventional electrodes may clog quickly in biological samples that have a high solids content such as wine must. By design, the pH electrode utilizes a polytetrafluoroethylene (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 HA-HI84502 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 600 rpm, regardless of the viscosity of the solution being titrated.
Easy-to-Use Interface The HA-HI84502 has an intuitive user design with clearly defined keys and a large screen that is easy to navigate. The meter has a built-in tutorial mode that, when enabled, will walk the user step by step through the titration process. A dedicated HELP key is always available to allow access to content-specific information during both calibration and titration.
