All 34 portable measuring arms offered in 6-axis touch-probing and 7-axis multi-sensor variants by LK Metrology, Castle Donington, are now supplied as standard with a 4.5 inch diameter mounting ring to allow the unit to sit on a larger base, rather than that provided by the previous 3.5 inch ring. The result of having this extra stability is that the new Version 3 FREEDOM Arms are capable of measuring to higher precision. A mounting ring adapter can be supplied if an existing user already owns an LK tripod or stand with a 3.5 inch mount. Mechanical, magnetic and vacuum fixing alternatives are available.
