Raw Milk Freezing Point Tester
 
Overview
CHL-100 raw milk freezing point tester (hereinafter referred to as the tester) is a precision instrument to measure raw milk freezing point depression by using the freezing point method. Because the freezing point is a relatively stable physical quantity among those of raw milk, and it changes obviously after being mixed with water or other matters, generally, the freezing point increases by about 6m℃ after adding 1% of water, and the variation can be measured accurately with a tester. Therefore, measuring the freezing point of raw milk is a good method to test the water content of milk and is simple and easy for promotion.
The tester can be used to measure the freezing point values of raw milk samples, calculate the relative water content based on the standard value set, display the values on the display control panel, and immediately print test results, thus it is easy to use and features intuitive display.
Main Technical Performance Indicators
Temperature Measuring Range: 0.0000℃ to -1.0000℃
Temperature Measuring Resolution: 0.0001℃
Freezing Point Temperature Measuring Accuracy: less than ±4m℃
Sample Volume: 2.5±0.1ml
Testing Time: 2 to 3min
