S12 STAGE MICROMETER
When counting asbestos fibre samples with a Walton and Becket graticule, the S12 Stage Micrometer is used alongside the HSE Test Slide to ensure that the microscope is correctly calibrated. The S12 stage micrometer is simply a microscope slide with a scale of 50 divisions of 0.002mm. The total length of the scale is 0.1mm and it is marked upon the surface of the slide.
Under ISO provisions it is necessary to provide traceability of the precise calibration of optical measuring equipment. Should traceability be required, your S12 Stage Micrometer will be engraved with a unique serial number and supplied with a UKAS certificate of calibration. Please don’t hesitate to contact us should you require further information.
