Are you looking for a quick and reliable measurement of egg quality?

HAUGH is the most recognised method used today for determining egg quality. HAUGH is measured on a scale of 1-100 and is calculated on the basis of egg weight in grams and the egg white height of the egg. Until now only manual equipment has been available to calculate the HAUGH unit, where egg weight is measured on a conventional, separate scale and the egg white height is subsequently measured using mechanical height measurement equipment. Previously height measurement in particular has been a very important element of uncertainty for each measurement, as it demands a great deal from the experience and skills of the laboratory technician to carry out the measurement according to the same exact premises. Another element of uncertainty is the manual processing of the calculation as the figures are entered into a computer or calculator. The findings depend on how disciplined the laboratory technician is.    

New technology from SANOVO ENGINEERING…
SHCI 110/220 from SANOVO ENGINEERING – Haugh & Colour instrument – takes these elements of uncertainty into consideration by automatically measuring the egg white height and instantaneous calculation. SHCI also differs from manual measurement by providing a considerably faster measurement and calculation. Measurement and calculation of both HAUGH and Colour is carried out in less than 20 sec.

Measurement of egg white height is carried out by the latest ultrasonic technology which allows high-precision measurements and touch free measurement. The measurement is carried out over 50 dots at intervals of 0.5 mm. According to these measurements an average value will be calculated which is included in the calculation of the HAUGH value.  
  
Including measurement of yolk colour…
The HAUGH measurement is carried out at the same time as the measurement of the yolk colour. Like the HAUGH measurement this measurement is also very accurate and uniform. The measurement is carried out by a RGB sensor and shows the result according to the Roche scale from 1-15. Definition of yolk colour is traditionally made by using a colour map according to which the human eye defines the colour closest to the present yolk colour.  This form of colour determination is commonly used in many other situations but often causes a lot of unnecessary discussion because the conditions vary, e.g.:

• Colours differ depending on the light in the measuring environment (direct sunbeams, daylight colours, electric lamps, fluorescent lamps).
• There are also individual differences between people. The colours are seen slightly differently depending on sex and age and whether it is night or day.
• Colours are seen differently depending on the colours surrounding the egg yolk. Grey is the colour with the least effect on the colour of the egg yolk.

HAUGH, including egg white height and weight, and yolk colour are shown on a digital display after each measurement and may be printed on the printer supplied or transferred to a traditional Excel based programme for data processing.
