Appears to be an ocular tonometer – measures eyeball fluid pressure or some such thing From: pianotech-bounces at ptg.org [mailto:pianotech-bounces at ptg.org] On Behalf Of Larry Fisher RPT Sent: Thursday, November 08, 2012 9:26 AM To: pianotech Subject: [pianotech] Prof. Schloetz's Tonometer While working for a dealership as an employee (a rather short gig) a young man handed me this gem from his recently deceased grandfather’s estate. He had no clue as to it’s origin or purpose. I gave him a few bucks and kept it in a drawer hoping to find an answer someday. The device is quite sensitive and comes with different weights (one has a 7.5 stamped on it and the other a 10). You can see it measures in the middle of the scale when balanced on top of a pool ball. There’s a small disk with a curved surface that is used for calibration purposes. The scale has no indication of units and spreads from zero to twenty. The numbers 2227 are stamped to the left of the scale. D.B.G.M. is stamped on the back of this scale. I’ve had thoughts of placing it on a bratwurst or knackwurst to check for firmness and such but I’d hate to get it dirty. PB031351 PB031350 PB031352 No virus found in this message.
