HI84502 Mini-Titrator for Total Acidity + pH/mV/°C Meter

Product information "HI84502 Mini-Titrator for Total Acidity + pH/mV/°C Meter"

The HI 84502 is simple, fast and affordable mini automatic titrator designed for testing total acidity levels in wine. It replaces the HI 84102 and features increased accuracy by improving the titrant delivery system and measuring ranges. The HI 84502 incorporates a precision dosing pump which allows for a highly accurate determination of the amount of titrant used. Pump calibrations, performed with the provided Hanna standards, assure the accuracy of the measurement. The HI 84502 also includes a new low range measurement.

The instrument includes a pre-programmed analysis method designed for total acidity measurements in wine analysis. The HI 84502 uses a powerful algorithm which analyzes the shape of the electrode response in order to determine when the titration reaction has reached completion. The results are displayed in g/L as tartaric acid.

The HI 84502 can also be used as a pH/mV meter.

FEATURES/BENEFITS:
* High accuracy piston driven dosing
* pH/mV meter
* Automatic Stirrer speed control
* Application specific pH electrode
* Real time graphing with exportable data
* Log on demand
* GLP feature, to view calibration data for the pump

FEATURES IN DEPTH:
Piston Driven Dosing – This dosing pump provides a highly accurate, repeatable result.

pH/mV Meter – In addition to being an automatic titrator, the HI 84502 also can be used as a pH/mV meter. While in Titrator mode, simply press “Meter” until pH units are displayed.

Automatic Stirrer Speed Control - Maintains stirrer speed at approximately 600 rpm regardless of viscosity of solution.
Application specific pH electrode – The HI 84502 is supplied with the HI 1048B pH wine electrode. This special electrode is designed specifically for measurements in wine and uses innovative CPS technology to reduce clogging of the junction.

Graphic Mode/Exportable Data – Display’s in-depth data on titration, which can then be stored using the log feature and then exported to a USB stick or transferred to a PC using the USB connection

Log on Demand – Log data on up to 400 samples (200 for titration results; 200 for mV/ORP)

GLP Feature – The HI 84502 includes a GLP Feature that allows users to view calibration data for the titrator and pump.
