This is an IP65 micrometer offering movement four times as fast as a standard micrometer. 

It presents you with the following benefits: 

• Faster measurement is achieved by using a coarser thread which feeds the spindle by 2 mm per thimble rotation.
• Extraordinary battery life of 2,4 years
• Outstanding accuracy
• Ratched thimble mechanism ensures easy single-handed or stand operation. Excellent resistance against water and dust (IP65 protection level) enables this micrometer to be used in machining situations that include splashing coolant fluid.
