First antifreeze measurements of heat transfer fluids compliant with the ASTM D 1177 standard

aqua-concept GmbH now offers you professional antifreeze measurement down to –70°C compliant with the ASTM D 1177 standard. We test ethylene glycols, monopropylene glycols, ethanols, but also other mixes using an automatic low-temperature PLC cryostat. Single and standard-compliant double determinations are possible. We provide you with a detailed analysis report and valid results to assess your system’s frost protection level. 

Why are professional antifreeze measurements so important?
Heat transfer fluids such as cooling brines, solar fluids or radiator antifreeze not only consist of pure glycol- or ethanol-water mixes but usually contain corrosion inhibitors or other additives. Traditional checks of the freezing point by measuring the density (using hydrometers) or by way of other physical-technical processes (refractometry) provide no exact results here because their inhibitors very often significantly falsify the measurements. An exact measurement compliant with ASTM D 1177 delivers genuine safety for the system.
