Key specifications
Nominal length: 20 mm
Accuracy class: Class 1 tolerance (precision grade)
Shape: rectangular gauge block
Typical use environment: workshop and laboratory measurement
How to use
Handle the gauge block with clean, dry hands or gloves to avoid transferring oils and contaminants to the measuring surfaces. Before use, clean contact faces with a lint-free cloth or approved cleaning solvent. For single-block checks, place the block between the measuring faces of the instrument and apply consistent measuring force as recommended by the instrument manufacturer. For building a stack, wring the block faces together using light rotational motion to ensure consistent contact and minimal air gaps. After measurement, remove the block, clean surfaces if necessary and store it in its protective case to preserve accuracy.
Usage recommendations
Use the gauge block within the ambient temperature range of the measuring environment and allow it to acclimate to local temperature before precision checks. Avoid exposing the block to corrosive environments, impacts or prolonged contact with moisture. Regularly inspect and maintain clean contact surfaces and follow laboratory or workshop calibration intervals to ensure continued measurement reliability.
