Thinp EKG Calipers ECG Caliper Measuring Tool with Ruler Black Caliper Divider for Nurse or Doctor Measuring Electrocardiographs

Pretty good calipers. Just don’t loose the sheath so you don’t stab yourself through your uniform.

I bought these for work. It measures just as it should. It's compact, so it doesn't take up much room and it's heavy/bulky to carry around. Seems like good quality so far. However, the tips are VERY sharp. I've stabbed myself a few times and gone through skin so be careful!

Love the metal and quality of these! Prefect to pass my dysrhythmia class!!! Great quality for a low price!

This is very effective to measuring out EKGs and determining what type of rhythm it is.

This caliper will be useful to you no matter what your field is, that's for sure! *(Someone once commented, "I didn't realize how useful calipers were until I got one, but I truly appreciated their value when I lost it!" It's a high-precision compass, and the case itself is a plastic caliper with white markings. This feature allows you to take measurements conveniently on the spot. If you're accustomed to using a Vernier caliper for precise measurements, but you also want quick measurements and the convenience of carrying the device in your pocket, then this unique and practical measuring tool is perfect for you!

This is a great device to transfer dimensions from one device to another. It is small and easy to carry. I am very happy with this.
