Wixey WR510 Digital Planer Readout with Fractions
This precision gauge has an angled display for easy viewing as well as "auto shut off." And it fits most portable woodworking planers. It easily mounts to Dewalt, Delta, Ridgid, Ryobi, Makita, Craftsman, and others. It mounts in minutes and is calibrated in seconds. It displays the thickness of the wood coming out the back of the planer in inches with fractions or millimeters. It is easy to attach the WR510 to your portable planer.  It comes with simple mounting brackets and detailed instructions that allow you to mount this on many models without even drilling a single hole. Calibration takes only seconds with its patented calibration system. The WR510 uses a piece of freshly planed board to ensure the readout displays the exact thickness of wood coming out the back of your planer. The large easy to read display reads in inches with fractions or millimeters. The fractions are displayed using “Precise Fraction Technology” which gives you 4 times the accuracy of other fraction readouts. The decimal inches are displayed in .005-inch increments, the fractions in 1/32-inch, and the millimeters in .1mm increments. Accuracy is .0025 decimal inches, 1/500 fraction inches, and .05mm metric.  Once it is set up and calibrated, the WR510 consistently displays the thickness of wood coming out the back of your planer. It never needs re-calibrated unless the battery is replaced or the blades get worn down. Advanced features let you zero the blade, remove a precise amount of material, or measure the thickness of any board.
