The HI96841’s IP65 water-resistant casing and sealed sample well are built to perform under harsh conditions, making it suitable for use in any brewery.
The °Plato scale is a way to quantify the concentration of sugars and dissolved solids in wort.
This measurement can indicate the potential alcohol content of finished beer. The HI96841 converts the refractive index reading to °Plato based on the tables maintained by the International Commission for Uniform Methods of Sugar Analysis (ICUMSA) and the American Society of Brewing Chemists (ASBC).
Refractive Index
The HI96841 takes measurements based on a sample’s refractive index. Refractive index is a measurement of how light behaves as it passes through the sample.
Depending on the sample’s composition, light will refract and reflect differently. By measuring this activity with a linear image sensor, the sample’s refractive index can be assessed and used to determine its physical properties such as concentration and density. In addition to the linear image sensor, the HI96841 uses a LED light, prism, and lens to make measurement possible.
Variations in temperature will affect the density of a solution based on the compound that is present. In digital refractometry, the use of temperature compensation is necessary for accurate results. The HI96841 contains a built-in temperature sensor and is programmed with temperature compensation algorithms in accordance with the ICUMSA Methods Book for a percent by weight sucrose solution.
Alcohol Interference
It should be noted that once fermentation begins, ethanol and the residual sugar interfere with each other and prevent an accurate reading of the Brix value of your residual sugar.. For this reason, this refractometer cannot be used with finished beer or other fermented beverages.
It is designed for use with wort only.
Features at-a-glance:
One-point calibration
- Calibrate with distilled or deionized water
Small sample size
- Sample size can be as small as 2 metric drops (100 μl)
Automatic Temperature Compensation (ATC)
- Samples automatically compensated for temperature variations
Quick, accurate results
- Readings are displayed in approximately 1.5 seconds
Dual-level LCD
- The dual-level LCD displays measurement and temperature readings simultaneously
Stainless steel sample well
- Easy to clean and corrosion-resistant
Battery indicators
- Battery percent level remaining at startup and low battery indicator
Automatic shut-off
- To conserve battery life the meter shuts off automatically after three minutes of non-use
IP65 water-resistant protection
- Water-resistant ABS plastic casing designed to perform under laboratory and field conditions
QUICK TIP:
Calibration procedures:
1. Press the ON/OFF key, then release. Two instrument test screens will be displayed briefly; all LCD segments followed by the percentage of remaining battery life. When LCD displays dashes, the instrument is ready.
2. Using a plastic pipette, fill the sample well with distilled or deionized water. Make sure the prism is completely covered.
Note: If the ZERO sample is subject to intense light such as sunlight or another strong source, cover the sample well with your hand or other shade during the calibration.
3. Press the ZERO key. If no error messages appear, your unit is calibrated.
Note: The 0.0 screen will remain until a sample is measured or the power is turned off.
4. Gently absorb the ZERO water standard with a soft tissue. Use care not to scratch the prism surface. Dry the surface completely. The instrument is ready for sample measurement.
Note: If the instrument is turned off the calibration will not be lost.
