Length Measuring
Peak Glass Measuring Scale 1972
Measurement of greater distances with measuring magnifiers is possible only to a limited extent due to the length of the scales. PEAK glass measuring scales are the optimum supplement for quick and simple determination of lengths and distances. The four lengths of 50 mm, 100 mm, 200 mm and 300 mm are supplied with a 15x reading magnifier (standard 1962 magnifier) in an elegant transport box. When measuring lengths and distances it is necessary to ensure that the scale is parallel to the object to be measured, to prevent measuring errors. A test report is not included with 1972 glass measuring rods, but is available if desired at additional cost and increase to delivery time by approx. 5-6 days. To make on offer for the report we require information on the number of measuring points/distances required in the report. Our subsupplier, who makes up these reports, is certified in compliance with EN ISO 17025 and EN ISO 9001:2000.

Peak Glass Measuring Scale 1972-S
Measurement of greater distances with measuring magnifiers is possible only to a limited extent due to the length of the scales. PEAK glass measuring scales are the optimum supplement for quick and simple determination of lengths and distances. The four lengths of 300 mm, 500 mm, 700 mm and 1,000 mm are supplied with two achromatic, focusable, 10 x reading magnifiers (see measuring magnifier 1983). The magnifiers on these measuring scales have a field of view of 20 mm. The acrylic mounts for the magnifiers have leaf springs integrated into the sides to prevent them from slipping. Separate silk lined boxes are included for the glass measuring scale and the two magnifiers. The graduations are 0.1 mm. The graduations with a width of 0.02 mm are marked in five heights (in Y) on the measuring rod. Graduation 0.1 mm = 1.0 mm, Graduation 0.5 mm = 1.4 mm, Graduation 1.0 mm = 1.8 mm, Graduation 5 mm = 2.4 mm and Graduation 10 mm = 3.0 mm.

When measuring lengths and distances it is necessary to ensure that the scale is parallel to the object to be measured, to prevent measuring errors.
A calibration certificate is not included with 1972-S glass measuring scales but can be supplied if required. The scales with measuring lengths of 300 and 500 mm can be supplied with a calibration certificate for the measuring magnifier in compliance with VDI/VDE/DGQ 2618 Sheet 27 Ü at additional cost. This increases the delivery time by approx. 5-6 days. To make on offer for the calibration certificate we require information on the number of measuring points/distances required in the calibration certificate. Our subsupplier, who makes up these reports, is certified in compliance with EN ISO 17025 and EN ISO 9001:2000.
