GRAN BARISTO 02 TECHNICAL SPECIFICATIONS 2.2.1. Specifi cation for the measurement of the coffee products temperature. The temperature is infl uenced by the fl ow from the dispenser and stratifi cation of temperatures in the glass. In order to consider these phenomena and to introduce measures that allow compari- sons in controlled conditions, below guidelines must be followed: Conditions: a) Water temperature in tank: 23°C (+/-2°C).

GRAN BARISTO 02 TECHNICAL SPECIFICATIONS 2.2.2. Specifi cation for the measurement of the Milk products temperature. Milk evaluation To carry out the test, a partially skimmed UHT milk with a percentage of grease between 1.5- 1.8% at a refrigerator temperature Trefr. (between 4 to 10°C) must be used. The milk product must be checked on a beaker of 250 ml of capability and with an inner diameter of 70mm, brewing 100gr of product.
