Mitutoyo Electronic Inside Hole Calipers with Calibration Certificate
These calipers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. Short, narrow contacts allow them to take hard-to-reach measurements, such as the dimensions of internal grooves and slots. All are IP67 rated for protection from dust and temporary water submersion. They have a zero-set button which allows you to start measuring at any point.
