The Advantages of Granite Inspection ToolsThe advantages of introducing granite equipment into the inspection environment have been known for some time. Cast iron and steel inspection tools are susceptible to rusting and bruising which can adversely affect the accuracy of measurements being made. Fine grained granite does not rust and has less tendency to bruise or burr. Granite is also non-magnetic and non-conductive and is less likely to be affected by change. Most importantly, the purchase and use of our granite inspection tools is probably more cost effective than ever.

On Site Granite and Iron surface table reconditioning and calibration service is available to BS 817: 2008 and supplied with UKAS certification

The equipment used by our technicians is calibrated to the relevant standards to ensure the highest level of accuracy possible and also that traceability is maintained. During the calibration procedure ambient conditions are monitored and recorded.

Our granite surface plate refers to the advanced standards of the leading countries, and its flatness tolerance is in accordance with the JB/T 7975-1999 Surface Plate:

Grade 000 =1x(1+d/1000)/μm

Grade 00 =2x(1+d/1000)/μm

Grade 0 =4x(1+d/1000)/μm

Grade 1 =8x(1+d/1000)/μm

(d is the length of the diagonal)
