ATAGO’s series of Abbe refractometers are named after Ernst Abbe, who invented the first refractometer in the 19th Century. ATAGO’s first refractometers were Abbe types, desk-top units with an eyepiece like a microscope. The NAR series continues this esteemed tradition, albeit with improved accuracy and reliability. The units in the series – the NAR-1T, NAR-2T, NAR-3T, and NAR-4T – distinguish themselves among ATAGO’s family of refractometers by their durability and their ability to measure the refractive index of solid samples.
