Chrome Glass Measuring Ruler with Micro-Scale, CSM Series
This high precision glass scale let's you measure as precisely as 0.01mm or 0.001".
Compared to the standard CS Series a further increase in the read-off accuracy is possible with the chrome micro-scale, CSM. A adapted analogue or digital dial gauge allows measurement of the distance between the one-tenth graduations. This allows precise measurements right down to one one-hundredth of a millimetre, 0.01mm.
These high precision glass scales have graduations and numbers created with vapour-coated hard chrome. Two scales are available in metric (0.10mm) and inch (0.005") increments. A white strip serves as a background on one side of the numbers to allow them to be read off more easily. The chrome scales are equipped with two anodised grips on the sides for secure handling.
Two precision magnifiers (type 2016 with 15x magnification and 12 mm field of view) in combination with two lights ensure simple, error-free read-off of the scale. The smallest increment on the inch scale is 0.005". The smallest increments on the metric scale are 0.1 millimetre.
An electronic measuring dial is available as an optional extra, which can be used as a substitute for the analogue dial. The function is the same, with the only difference being that the display of the intermediate scale values changes from analog to digital. Bear in mind that the electronic measuring dial can only transfer the intermediate values and not the total measured distance.
These valuable precision glass measuring rulers are delivered in a stable wooden case to protect them from damage and are available in lengths of 300, 500, 800, 1000 millimetres. Special lengths available on request. These glass measuring rulers have the advantage that their expansion is minimal when heated. Temperature variations therefore have hardly any effect when using chrome scale rods.
