Unfortunately I ordered the wrong size and had to return it. It looked good and when I get a chance I will call the supplier and find out the correct size and order it.
Pros
Supply Voltage range: AC 80V~260V; 50~60Hz, Resolution 5um/0.0002.Pulse signal period 20Β΅m , Available Measure Length 70mm.
Cons
The glass linear scales are prone to breakage and therefore need to be handled with care
