For those who want the benefit of a direct-reading display, we offer a digital readout for use with the Mast-R-Lift Excel II. With easy-to-read 5/16" high numerals, it displays in decimal inches to 0.001", fractional inches to 1/32", and metric to 0.1mm. It performs differential measuring without recalibration and can be zeroed at any point. Accurate to ±0.002"/0.05mm. An easy retrofit, the sensor simply mounts to the router carriage, and the readout attaches to the table with machined aluminum mounting brackets. All installation hardware supplied. Operates on two AAA batteries (not included).
