Portable EBC Haze Meter - HI93124

The HI93124 Portable EBC Haze Meter is a highly accurate portable meter for beer analysis that reflects HANNA’s years of experience. The HI93124 has been designed to perform turbidity measurements according to the EBC (European Brewery Convention) Standard, utilizing a nephelometer to test for turbidity caused by haze. The meter is specially designed for beer quality measurements, providing accurate and precise readings every time.

  • Compliant to EBC methods
  • Auto-off
  • Data logging up to 199 measurements


The HI93124 Portable Haze Meter is specially designed for measurement of haze in beer quality analysis. 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. The 10 mm round cuvettes composed of special optical glass guarantee the repeatability of turbidity measurements.

Features at-a-glance

EBC Compliant Measurement –The HI93124 meets the requirements of the EBC standard for haze measurements. Measurements are taken from beer samples that have been degassed, and results are reported in European Brewery Convention units (EBC).

Calibration – A two or three point turbidity calibration can be performed by using the HI93124-03 calibration standards

AMCO AEPA-1 Primary Turbidity Standard – The AMCO AEPA-1 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.

GLP Data –The HI93124 features GLP (Good Laboratory Practice) functions that allow traceability of the calibration. Data includes date and time.

Data Logging – Up to 199 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 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.

Significance of Use

Beer clarity is a parameter constantly controlled in the brewery. Clarity can be affected by haze, an insoluble or semi-soluble particulate matter which is small enough to form a colloidal suspension in beer. These particles scatter transmitted light and are observed as a degradation in the brilliance of the beer. To assure consistent product quality, the brewmaster needs more than visual inspection.

Several substances can cause haze in beer, but the most frequently encountered problem is due to a cross-linking of polyphenols and proteins. These materials exist in equilibrium in beer and manifest themselves as a haze when they combine to form insoluble colloids. A range of stabilization treatments is available for avoiding haze problems, and the product has to be controlled in several steps during the brewing process, particularly after filtration and before the beer enters the bright tanks.

The HI93124 Portable Haze Meter reports the measurements in EBC (European Brewery Convention) units. EBC units are ¼ of an FTU and FTU units are equal to NTU units (Nephelometeric Turbidity Units). The conversion table between these measurement units is shown below:

The HI93142 is designed according to the EBC standard for haze in beer measurements, compensating for beer color to guarantee accuracy. The light beam that passes through the sample is scattered in all directions. The intensity and pattern of the scattered light is affected by many variables, such as wavelength of the incident light, particle size and shape, refractive index, and color. The optical system includes an LED light with a 890 nm wavelength and a scattered light detector (90°). The HI93142 features a powerful microprocessor that calculates the EBC value from the signal that reaches the light detector.

turbidity measurement

The HI93124-03 AMCO AEPA-1 standards ensure that measurements are traceable to primary reference materials. These standards are used for calibration and performance verification of the turbidity meter.
