The gauge comprises a precision machined alloy block, into which the linear scale of the Digital Readout (DRO) is bolted. This fixing is set very precisely at right angles to the base, to ensure accurate measurement. The linear scale is also marked with analogue scales from 0-6" and from 0-150mm. These scales are read against the lower edge of the Digital Read Out.
There are three rare earth magnets set into the base of the block to ensure the gauge is held flat against a horizontal ferrous metal surface. The digital readout is mounted on the linear scale and has an 'L' shaped pointer attached to it; there is also a small locking screw with a serrated knob that will clamp the DRO. The 'L' shaped pointer is ground to a fine edge to ensure the most accurate measurement; it is also hardened so that the points can be used for scribing lines at the set height.

GoodI bought this to adjust my router table bits. It came in a cardboard box with plenty of protection, just wish it came in a smaller wooden box so I can store it easily as the original box it massive. Also the description mentions something about 3 large rare earth magnets, well it comes with strips of magnets under the base, they work ok but can't hold the gauge on a vertical surface. Other that it is a very useful piece of kit.

NiceThis is a nice item, well packaged, comes with a spare battery too. It works very well, and is nice and smooth, also has an output for a DRO. Well worth the money.

Axminster digital height gaugebought for use with a cast iron router table. Works well but a simple modification would be a packing piece at the top of the column to support it accurately in the horizontal position for measuring cutter to fence distances
