The vernier caliper, is a measuring instrument equipped with a scale and a cursor that slides in itself. In the cursor is recorded a second scale called vernier scale or nonius. A Vernier allows a precise reading of some value. In the figure to the right, the Vernier moves up and down to measure a position on the Scale. This could be part of a barometer which reads atmospheric pressure.
Comparing to the digital vernier caliper manufacturers china, traditional manual calipers were limited by the visual acuity of the operator. A special scale was developed by French mathematician Pierre Vernier in 1631; it was designed to improve accuracy of eye-sighted calibrations. Instead of holding a scale up to an object, this device is placed in or around the object while its two scales are compared using the slightly more user-friendly process of aligning lines between scales. The sliding scale is constructed as a constant fraction of the main scale in order to make calculations easier.

Beekeeping is a unique and highly skilled operation. The Beekeeping Industry in Western Australia has a high proportion (66%) of workers with no post-secondary qualifications. The low qualification levels have significant implications for the industry in terms of keeping up to date with modern beekeeping practices, attracting young workers to the industry, and for succession planning. The industry has a proud reputation of producing the ‘cleanest’ honey in the world – i.e. produced by ‘disease free’ bees.
There are no entry requirements to become a beekeeper. Most skills can be learned on the job, but a tertiary qualification in beekeeping is useful. Employers may support their beekeepers to complete Disease Elimination Conformity Agreement (DECA) training – to make sure they can recognise American foulbrood disease.Many employers require their beekeepers to have a driver's licence and a heavy vehicle licence, and some may support staff to gain heavy truck and fork-lift licences.
