ATAGO ethyl alcohol refractometer Model PET-109 Includes instruction manual and two 006P (9V) batteries Purchase price: approximately 110,000 yen Operation has been confirmed. Batteries are included, so you can use it immediately upon arrival. I'm not sure if the box contains a full set of accessories. I have confirmed the power and zero adjustment, and I have been told by the previous user that the measurements were also accurate. I intended to use this for work at my parents' house, but it hasn't been used much, so I am selling it.
