C124 Beer Quality Haze Meter

  • Sophisticated yet portable – Quick and easy laboratory grade results anywhere in the brewery.
  • Good Laboratory Practice (GLP) - With the press of a button, the last calibration information is retrieved from memory and displayed to assure accurate measurements.
  • Logging Capability - This powerful feature allows you to store information from up to 200 samples including the time and date of each measurement.
 
Now there is an accurate and affordable way to determine beer haze. Beer clarity is an important factor influencing consumer acceptance since the presence of haze in beer is usually associated with inferior quality. Haze in beer is a natural phenomenon that can be observed after storage for one to three weeks. The two most important causes for haze formation are proteins and tannins, and proper treatment is required to prevent or delay its formation. A common way to determine beer haze is by visual comparison. This method however is subjective and inefficient.

Hanna’s C 124 is a professional haze meter using the nephelometric method (measurement at 90° angle) combined with an infrared light source (890 nm) to reduce color interference. In addition, since haze is normally measured after chilling at 0°C (32°F), the C 124 is supplied complete with Hanna’s high accuracy Checktemp® digital thermometer.
