A micrometer is a measuring device to gauge the thickness of very small objects such as paper, foil, board, rubber etc. Micrometers are usually small hand held devices with gauge readings either being displayed on a dial, digital read out or winding spindle. Micrometer stands are also available.
Digital read out units are available which plug into some versions of digital micrometers (power of battery operated) which read out the measurements to the user with the push of a button and are generally volume adjustable. They have capacity for ear or head phone attachments to enable clear hearing of speech in a noisy workshop, with some models also allowing for printer attachment. These read out units can usually be transferred to other tools such as digital callipers.
Tactile micrometers are also available which have deeply etched markings to enable distinct measurements to be ‘felt’ rather than read.
Workplace solutions and adjustments:
For individuals who are blind or vision impaired and working in a position requiring precise measurements of very small objects such as paper thickness, talking micrometers may be of assistance in ensuring ongoing measurement accuracy.
Some read out units are also available with a printer if printed rather than audible measurements are more suitable. Other talking tools available include:
