HI84533 is an automatic mini-filter and pH meter designed for fast, accurate determination of assimilable nitrogen (formaldehyde index) in grape musts and fruit juices.
It features a piston dosing system controlled by a dynamic dosing algorithm, optimizing measurements. The compact casing ensures a compact workstation footprint. The titrator is also equipped with automatic stirring speed control, a graphical mode generating the tritration curve in real time, PC-readable data storage and a Good Laboratory Practice (GLP) function, enabling users to consult pump calibration data.
HI 84533 has 2 operating modes:
- pH measurement using the instrument in pH mode.
- Determination of formaldehyde index by titration with sodium hydroxide (NaOH) at pH 8.2 endpoint (a sample preparation step is required).
HI84533-02 comes complete with HI1131B pH electrode, HI7662-T temperature probe, HI84533-70 reagent kit for assimilable nitrogen (formaldehyde index), HI70500 tubing kit with cap for titrant solution bottle, tip and valve, HI7082 electrode filling solution (30 mL), cleaning solutions for wine deposits and stains, 2 x 100 mL beakers, 1 x pump valve, 1 x 5 mL syringe, 1 x 1 mL plastic pipette, 1 x magnetic bar and 12 V mains adapter.
Highlights:
- New: dynamic dosing with precision piston pump
