• Revolution counter
• Using universal fonts, changing dial face color and reviewing the relationship between pointer and scale marks have drastically improved visibility
• Glare-free flat crystal face allows easy reading of graduations
• The O-ring seal on the bezel has the effect of providing smooth rotation and prevents dust and oil from penetrating through to the dial face
• Bonding the bezel and crystal together leaves no gap for cutting fluid or oil to penetrate through to the dial face
• A flange prevents the bezel from unintentional removal due to applying a force to the bezel during handling
• Horizontal type (the standard model): the dial is on top of the frame
• Hard, antifouling and non-glare coatings on the crystal inhibit scratches, contamination and glare on the surface
• The conventional method of mounting the stylus pivot bearing screw in the frame is prone to allowing looseness to develop with prolonged use. A unique sub-plate structure to house this screw has now been incorporated in all models and eliminates this issue
• The ability of the indicator to track small changes in displacement deteriorates due to minute changes in clearance between the gears with prolonged use
• As the length of the stylus fitted affects the indicator's scale factor the length that gives a scale factor of unity is marked on the dial face to assist a customer when ordering the correct replacement stylus
• A ø8mm (ø0.315") plain stem (21CAB104) for the Metric models or a ø9.52mm (ø3/8") plain stem (21CAB105) for the Inch models that attaches to any dovetail on the frame is supplied as a standard accessory
• Certificate attached
