About the 4912 Series Inside Micrometers...

The Dasqua 4911 & 4912 Series of Inside Micrometers presented are available in 10 models. 5 models are available with metric graduations of 0.01 mm with a measurement range from 5 to 100 mm across the different models. The Imperial versions are graduated in 0.001” and feature a measurement range from 0.2” to 4 inches. Dependant on the measurement range, the inside micrometers come in two jaw types, type A and type B.

The 4911 & 4912 Series are designed to accurately measure various inside dimensions. The inside micrometer features a ratchet stop for constant pressure. The high-quality spindle is thread hardened, ground and lapped for high accuracy. Clear graduations are laser etched onto the satin chrome finish for easy reading.

This model features a spindle lock, and the jaws feature carbide anvil measuring surfaces that are accurately ground for high precision and long service life. Certain models of this series come with an ultra-precision ring gauge for self-calibration in controlled environments.

Other notes

*This is precision piece of inspection equipment and great care should be taken whiltst using and storing it. Significant enough drops, bangs and impacts while likely cause irrepairable damage to the unit and/or its funcitonality and precision accuracy. Good engineering / manufacturing practice (GMP) should always be maintained to minimise the risk of rust developing and damage protection. 

**Batteries are not shipped with with certain carriers, and in some circumstances can be removed at customs, therefore it is best practice to assume that batteries are not included for the purposes of any continency actions that may be taken at despatch or in mid transit.
