法国采购需求：粗糙度和圆度测试仪，表面轮廓仪

I'm in need of a reliable tool to accurately measure the thickness of surface defects on glass products. I came across a specific surface profile gauge that seems to fit the bill perfectly. Could you provide a quote for a batch of 4 units? Additionally, I'm a bit concerned that the gauge's base size might be too large for some of the narrower applications I have in mind. Do you offer alternative options with a smaller base that would be suitable for tight spaces? Looking forward to your swift response.
