Atago Digital Hand-held "PEN" Sodium chloride Refractometer PEN-SW (Baume)‎


"Dip," "touch," "stir!" The simple and convenient measurement methods of the PEN Series now include a unit equipped with the Baume scale. The tip (sample stage & prism head) of the PEN is made out of SUS316, making it highly resistant to corrosive, salty samples.
