Affordable Approach to Reliable, Real-Time Results
A practical approach to testing for added-water in unprocessed or processed fluid milk products, the straightforward simplicity, affordability and reliability of the QuickCheck is a sound investment:

  • Artisenal Cheesemakers: Many cheesemakers have to rely upon milk from unknown sources to ensure a steady supply for processing. The QuickCheck makes it easy and affordable to reliably test every incoming shipment of raw milk to ensure that you are getting the quality of product you require. Also, the QuickCheck can be used to check milk that has been standardized for processing to ensure that no added water has come in during the process.
  • Dairy Processors: Conforming with internationally recommended methods for testing for adulteration, the QuickCheck provides you with ultra-accurate results at an affordable price. The Amplified Performance Module also ensures that you get reliable results even when ambient temperatures rise to 35°C (95°F)!
  • Dairy Farmers: Monitor practices in your milking parlor and avoid costly mistakes or fines by testing your bulk milk tank for added water. The unique combination of user-friendly operation, stable calibration and an attractive price make the QuickCheck a worthwhile investment for today’s dairy farm.

A Purchase Decision that Pays Off!

  • Facilitate confirmation of adulteration using this instrument-based physical composition test that is the recognized reference method (ISO/IDF/AOAC). Provides optimal records for payment or punitive action purposes.
  • Accurately assess water balance to a molecular level in milk blends and recipes for value added products like cheese or yogurt. Reliable quality assurance test to standardize recipes and ensure strong yields and profitability.
  • Rapid screening for detection of abnormal composition (i.e. minerals such as iron, sulfites or copper) or elevated bacteria that can lead to off-tastes.
  • Monitor suppliers maintenance of automated milking tubing and bulk tanks; spot quality problems in raw milk due to improper drainage or maintenance in the milking parlor.
