Mitutoyo Laser hollow gauge (with counter EH, 542-715)

Achieves high resolution and high accuracy of 0.005μm or 0.01μm, comparable to that of a laser interferometer, over a wide range of 10mm.
The compact body contributes greatly to the miniaturization of the device itself, and is ideal not only for measuring high-precision parts and as a length measuring sensor for high-precision positioning and control devices, but also as a master gauge for measuring instruments.
Low measuring force specifications also available: Low measuring force specifications can be selected according to the application, making it possible to measure workpieces that are easily deformed and high-performance films.
The LGH series comes as a set with a dedicated counter.
Equipped with a newly adopted photoelectric reflective linear encoder, it achieves a high resolution of 0.01 μm, an indication accuracy of 0.2 μm, and a wide range of measurement of 10 mm at a low price.
The response speed has improved 2.8 times (250mm/s to 700mm/s) compared to previous products, achieving both high precision and high speed.
