A set of two glass conformance filters for checking the 3000 Comparator in Gardner scale
编号 342000
产品信息
Conformance filters are assigned a nominal value and the company always endeavours to match this value as closely as possible. On occasion, because of the unique manner of the glass making process, it may not be possible to match the requested values exactly. The values achieved and the performance tolerances expected will, of course, always be reported.
