ASTM, D1218, D1569, D1807, D1992, D2140, D4056, D4095, ICUMSA, GS4/3-13, SPS-3, ISO, 1743, OIML, R124
The KEM refractometer is Fully Compliant with methods ASTM D1218, ASTM D1569, ASTM D1807, ASTM D1992, ASTM D2140, ASTM D4056, ASTM D4095, ISO 1743, ICUMSA GS4/3-13, ICUMSA SPS-3, and OIML R124. This refractometer (RA-620/RA-600) is a precision instrument which measures the refractive index of liquid samples. The reflection signal of LED light from prism received by CCD (charge-coupled device) is computed by the built-in processor, and measurement results appear on display immediately. Therefore, utmost care should be taken when you install or handle the product.
This KEM Refractometer has touchscreen operation. One of the smallest to fit in A4 size (192 x 281mm). Comes with KEM Refractive Index Standard Liquid Completely ready for use Short warm-up time. Display & sound can be customized on this digital portable Refractometer. Easy operation & maintenance-free.
