This tri-scale digital refractometer is great for car mechanics and fleet managers wishing to check the concentration of Diesel Exhaust Fluids (commonly known as DEF or AdBlue®) that form part of a NOx reduction system in diesel powered vehicles. In addition, this particular OPTi digital refractometer not only displays %DEF but also comes with scales for measuring °C Ethylene Glycol (°C Freezing Point), ideal for measuring automotive coolants such as Antifreeze, and Sulphuric Acid for testing battery acid.
Scale A is set to AdBlue (DEF)
Scale B is set to (°C Freezing Point)
Scale Cis set to Sulphuric Acid (battery acid)
The OPTi Digital Handheld Refractometer - Automotive (AdBlue - DEF/Ethylene Glycol/Sulphuric Acid) scales are preselected at despatch, but may be reassigned using the scale selection method detailed here.
