FIELD TEST APPARATUS AND METHOD FOR THE DETERMINATION OF COOLANT CONTENT AND FREEZING PROTECTION

摘要

A method and apparatus are provided for the determination of levels of components of coolants and heat exchange fluids, particularly monoethylene - and monopropylene - glycol content. Refractometric and gravimetric values are taken and the volume fraction of the individual components obtained by inverting a system of linear equations. A microprocessor controlled field test apparatus can compute the various values to be determined.
