5-SCALE DIGITAL REFRACTOMETER


The PEAK 5-Scale Digital Refractometer has been specifically engineered to accurately measure the percentage of DEF urea levels. Maintaining proper urea levels in DEF is absolutely crucial to ensure optimal operation of Selective Catalytic Converters—which makes this refractometer an industry must-have.

To operate, simply add a few drops of DEF to the device. The PEAK 5-Scale Digital Refractometer meets or exceeds the requirements for refractometers in international standards ASTM D7821 and ASTM D3321.
