We offer latest designed ultrasonic milk analyzer which is efficient in giving correct measurement of fat content in the milk. The advantage of the analyzer over other conventional electronic milkotester is that it is fully automated. In case of the conventional one, it requires to move 3 times the handle of milkotester for having the fat reading. In a co-operative / private milk society, there are usually hundreds of members working with it. Speed of handle movement for 3 times may vary with each member causing variation in the readings of fat. The error in the fat reading is loss to either the society or the member. The problem can be overcome by our ultrasonic milk analyzer which is an automation unit. An existing milkotester (any make) is connected with our automation unit with ease. The handle movement of the milkotester is started automatically once the press button is pressed. After every 3 strokes, reading of the fat content of the milk sample is displayed.
