Overview
The HI83749 Liquor Turbidity and Silica Saponite Tester is specially designed for the measurement of wine turbidity. It is based on a reliable Optical inspection system to ensure accurate results and long-term Stability, and to reduce stray light and Color interference to low levels. The instrument is used to determine the initial turbidity of unrefined wines. Stability is judged by adding a pre-prepative solution for secondary measurement. Measurement range 0.00 to 1200 NTU, in accordance with USEPA standards.
Features
1. Alcohol turbidity - silica bentonite determination, automatic range conversion, large screen display
2. Average Measurement mode (AVG): Average of multiple readings to ensure accuracy
Compliance with USEPA Standards and Standard Method 2130B
4. GLP management function, query settings, calibrate, time and other information
5. Manual calibration, built-in standard calibrating point: < 0.1, 15, 100, 500 NTU
6. USB-RS232 Dual Interface, 200 Data storage, Good data management
Principle
A turbidity measurement based on a reliable Optical inspection system ensures accurate results and long-term Stability, and reduces stray light and Color interference to low levels, also compensating for changes in lamp intensity. A 25mm round reaction cup consisting of special Optical inspection Glass guarantees repeatability of turbidity measurement. The winemaker determines the wine Stability by comparing the two readings by measuring the initial turbidity of the unrefined wine, adding a pre-prepative solution and performing a second turbidity measurement.
Applications
Wine turbidity measurement, wine silica bentonite determination
Standards
USEPA Standard Method 2130B, USEPA Method 180.1
Steps
1. Determination of the initial turbidity of unrefined wine
2. Add the H183749-20Bentocheck solution to the wine sample
3. Second turbidity measurement
4. Comparing Two Turbidity Readings to Determine Wine Stability
Notice
• If the second turbidity reading is less than the initial turbidity reading plus 2NTU, the wine is considered stable
• Otherwise a clarification test can be performed to determine the amount of ardomorite that must be added
Due to the different types and masses of ardomorites, their ability to remove proteins also varies
• It is important to use the same batch and wetness of ardomorite for laboratory experiments
