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

The 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 AdBlue.The unit can be used to check the proportion of battery liquid, instead of the use of hydrometer. Safe and reliable. This product is used to measure the freezing temperature limit of automotive coolant. It is used as a tool to protect the car engine. The instrument is resistant to abrasion and corrosion resistance. Can be measured acidic and alkaline and other general
