The definitive bench micrometer, the Universal Supermicrometer®, offers the advantage of being two instruments in one, by providing the ability to measure both internal and external parts, gages or standards. The Universal Super Micrometer / Universal comparator is designed to measure external threads, plugs, pins, wires, dial indicators, ring gages, as well as your precision parts. (read more)

With instrument uncertainty to 2 millionths of an inch (50 nanometers), its suitable for OD applications such as gage blocks, ball bearings, optics, and film thickness. The Labmaster Standard is the fastest gage block comparator on the market today. (read more)

If a large direct reading range is important to you, choose the Labmicrometer measuring system. Designed for gage calibration laboratories requiring precise internal and external measurements over long lengths, it's popular with aerospace and defense contractors. Common applications include measurements of end/length standards, long gage blocks, plug/pin gages, thread gages, and rings. (read more)

If you're looking for a direct-reading metrology instrument and an electronic size comparator for use on the production floor, look no further – the third-generation External Supermicrometer® provides durability, digital accuracy, speed of measurement, and range of applications. (read more)

Your solution for vertical measuring is the Laseruler® which is laser-interferometer-based for very high accuracy. Our exclusive digital interferometer measures the dimension of the part by comparing the measurement probe position to the wavelength of a HeNe laser light source, effectively coupling the wavelength of light to the part being measured.
