The Optigraph is designed to measure, renneting ability, coagulation characteristics, formation of curd and firmness in milk using near infrared technology—all in real time.

Up to 10 samples can be measure simultaneously using 10 mL cuvettes.  Temperature control of the cuvettes can be set between 25° to 45°C.  The instrument goes through an auto calibration cycle before each test to ensure the quality and reliability of the data.

The Optigraph has no moving parts and only the measuring cuvettes need cleaning after each use.
