Starrett No 2500-5 Electronic Indicator. Here's my used Starrett 2500-5 electronic 1 travel indicator. The bezel rotates 270 degrees and works on two #357 button batteries. I bought this new around 30 years ago and only used it for about one year.
For a short time I ran a VTL turning large rolled fabricated drums. Indicating them in was difficult as a dial indicator would be swinging plus & negative so much I wouldn't know where I was. So using this in the center of the 1 travel and pushing the zero button made plus & minus simple to see. I used a roller point on this indicator which I'm including. Only ran that machine for about a year, removed the batteries and never used this again.Original box and instructions included. I did scribble out some ID engraving on the side of this indicator.
Please look at all the pictures carefully and ask any questions you may have.
