EKG caliper with hardened steel arms and points for accurate measurement of tracing intervals. Point protector has built-in 40mm metric scale. Measures 4 3/4".
I use many of these calipers when teaching cardiac rhythm classes. These are a good product for my students.
This lil caliper is pocket sized and makes measuring telemetry strips easy.
Great for the price.
Decent set of calipers...the tele guys approved, so I'm happy with them!
Works just as planned.
