3-in-1 Refractometer Ethylene Glycol, Propylene Glycol in antifreeze liquids freezing point temperature and freezing point concentration, automotive and industrial battery liquid,by Hamh Optics&Tools Arts Grow more in less space-multipleThe models have only one unit system: . With the indication of the percentage we may know the freezing point of either ethylene glycol or propylene glycol based cooling systems. You can use it to check the temperature (freezing point ) of the condensation of your cooling water. This product has been improved to a higher level of accuracy. The measured data is close to the ASHRAE standard. The new product adds functionality and can be used to measure
