The Misco Palm Abbe DEF-201 is a handheld digital refractometer designed for testing the concentration of urea-based diesel exhaust fluid (DEF).
This test requires a few drops of urea-based Diesel Exhaust Fluid to obtain a digital reading of urea concentration with a precision of +/-0.1 per cent.
Users place a few drops of DEF in the refractometer's stainless-steel well, close the evaporation cover and press a single button to obtain an instantaneous reading on the large 24-character backlit display.
The refractometer can be quickly calibrated to water with the touch of a button.
Misco's Optical Engine combines high-index sapphire optics with a detector array containing more than a 1,000 detector elements.
The instrument also has an optimised combination of hardware and software that automatically temperature compensates the reading specifically for aqueous urea solutions.
In addition to reading DEF, the refractometer can be programmed to read up to four more critical automotive parameters such as engine-coolant freezing point, engine-coolant concentration, brake-fluid water content and windshield washer fluid.
Each refractometer bears a laser-etched serial number for traceability.
Options for the instrument include a rubber-armour jacket (in one of three colours), a virtually indestructible storage case and NIST-traceable certified calibrations.
