A BRIX type Optical Refractometer for measuring the strength of cow colostrum.-POSSIBLY NO CASE SUPPLIED, as this varies with supplier.
Put a drop of colostrum on the slope, lay the cover over to spread the colostrum, hold upto the light and read the strength through the eyepiece.
A horizontal line in the screen gives you a reading. a reading of 22 or more on the Brix scale is GOOD TO GO!
Lower than 22 colostrum should be used for second or later feeds OR fortified with our First Thirst Colostrum fortifier.
Call us if unsure how to use.
