HI83749 Portable Turbidity and Bentonite Check Meter

HA-HI83749-02

The HI83749 is a portable turbidity meter for the monitoring of protein stability and bentonite in wine. The meter is supplied complete with bentocheck reagent and AMCO-AEPA-1 primary turbidity standards. The bentocheck reagent is used to determine the amount of bentonite required to increase protein stability and the AMCO-AEPA-1 primary turbidity standards are used for calibration and performance verification of the meter.

The HI83749 Portable Turbidity and Bentocheck Meter is specially designed for measurement of turbidity in wine. The instrument is based on a state-of-the-art optical system which guarantees accurate results, assures long term stability, and minimizes stray light and color interferences. It also compensates for variations in intensity of the lamp, although proper calibration ensures measurements are fully validated, comparable, and in compliance with regulatory requirements. The 25 mm round cuvettes composed of special optical glass guarantee the repeatability of turbidity measurements.

Features at-a-glance:

AMCO AEPA-1 Primary Turbidity Standard - The AMCO AEPA-1 supplied standards are recognized as a primary standard by the USEPA. These non-toxic standards are made of styrene divinylbenzene polymer spheres that are uniform in size and density. The standards are reusable and stable with a long shelf life.

Calibration A two, three, or four-point turbidity calibration can be performed by using the supplied (<0.1, 10, 100, and 500 NTU) standards. Calibration points can be modified if user-prepared standards are used.

Fast Tracker - For users taking measurements throughout the winemaking process, the HI83749 is equipped with Fast Tracker - Tag Identification System (T.I.S.) that makes data collecting and management simpler than ever. Fast Tracker allows winemakers to record the time and location of a specific measurement or series of measurements using iButton tags on specific tanks for quick and easy readings. Each iButton® tag contains a computer chip with a unique identication code encased in stainless steel.

GLP DataThe HI83749 features complete GLP (Good Laboratory Practice) functions that allow traceability of the calibration conditions. Data includes calibration points, date, and time.

Data Logging Up to 200 measurements can be stored in the internal memory and recalled at any time.

Data Transfer For further storage or analysis options, logged data can be downloaded to a Windows compatible PC using the RS232 or USB port and the HI92000 software.

Backlit Display – A backlit LCD display provides an easy to understand, user-friendly interface. Displayed codes guide the user step-by-step through routine operation and calibration.
