For mid-infrared analyzers (RBLSM), which consist of 13 different concentration milk samples, where the fat content range varies from 2% to 7%, protein content – from 2% to 7%, lactose content from 4,5% to 5,5%, total dry matter content – from 10% to 16%.
For milk freezing point analyzers (UT), which consist of 10 different milk samples with freezing point values between minus 490 mºC and minus 530 mºC.
For urea parameter analyzers in milk (Ur) we offer set, consisting of 10 different milk samples with urea content between 10 mg/100 ml and 65 mg/100 ml.
