Measurement of greater distances with measuring magnifiers is possible only to a limited extent due to the length of the scales. PEAK glass measuring rods are the optimum supplement for quick and simple determination of lengths and distances. The five lengths of 50 mm, 100 mm, 200 mm, 300 mm and 400 mm are supplied with a 15x reading magnifier (standard 1962 magnifier) in a transport box. When measuring lengths and distances care must be taken 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, which are produced in compliance with international standards.

Upon request and for an additional charge the glass measuring rods are supplied with a factory calibration certificate (up to 400 mm) or DAkkS (up to 200 mm). This will increase the delivery time by approx. 3 weeks.

Technical data for glass scales 1972:
