Surveilance Masters

We produce a large number of surveillance masters in all sizes. Below is a gallery and short description of the masters. If you would like to see prices, please see our pricing guide. Please choose from the following to see a description of our masters.

GSG Micrometer masters are used to calibrate and set micrometers. The master is superior to gage block calibration because they do require block stacks and therefore it is much faster to inspect the linear range of the tool. In addition they indicate wear on the micrometer anvil because it replicates how the micrometer is used.

Model # 01-1

Model # 01-1E (English) Model # 01-1M (Metric) 01-1 diameter is Stainless Steel to reduce wear and prevent rust. Hardened, stabilized, ground and lapped to +/-.0001. Comes complete with storage case.

Model # 16-1/2

Model # 16-1/2E (English) Model # 16-1/2M (Metric) 1/2Â-6.00 diameter in 1/2 increments 12.5-150mm diameter in 12.5mm increments Case hardened, stabilized, ground and lapped to +/-.0001 or +/-.0025mm.

Model # 01-1

Model # 01-1E (English) Model # 01-1M (Metric) 01-1 diameter is Stainless Steel to reduce wear and prevent rust. Hardened, stabilized, ground and lapped to +/-.0001. Comes complete with storage case

Model # 112E

Model # 112E (English) Model # 112M (Metric) 1.00-12.00 diameter in 1.00 increments 25-300mm diameter in 25.0mm increments Case hardened, stabilized, ground and lapped to +/-.0001 or +/- .0025mm.

GSG

GSG Vernier masters are used to calibrate and set Vernier calipers. The master is superior to gage block calibration because they do require block stacks and therefore it is much faster to the inspect linear range of the tool. In addition they indicate wear on the caliper anvils because both the ID and OD jaws are inspected without additional setup.

GSG Vernier Caliper Masters

Model # VC-1E (English) Model # VC-1M (Metric) 1.00-6.00 diameter in 1.00 increments for outside jaws, 1/2 to 4 1/2 inside jaws. +/-.0002, 25-150mm diameter in 25.0mm increments for outside jaws, 12.5 to 112mm for inside jaws +/-.005mm Case hardened, stabilized, ground and lapped to +/-.0002. Larger sizes are available upon request.

GSG Depth Micrometer Masters

Model # ADM-E (English) • .5-5.50 in 1.00 steps +/-.0001 • 6.5-11.50 in 1.00 steps +/-.0002 Model # ADM-M (Metric) • 12.5-137mm in 25.0mm steps +/- .0025mm • 162.5-287mm in 25.0mm steps +/-.005mm • Case hardened, stabilized, ground and lapped.

GSG Geometric Chek Master

GSG Geo Metric Chek masters are used to calibrate and set circular geometry systems. The master checks for perpendicularity (squarerness), parallelism, roundness and concentricity. Model # GC-1 Master is supplied with complete certification for roundness, parallelism, perpendicularity and concentricity.

GSG Z Axis Chek Masters

GSG Z Axis Chek masters are used to calibrate and set the z axis on optical measuring machines. The master is superior to gage block calibration because they do require block stacks and therefore it is much faster to inspect linear range of the machine. Model # LX-1 (lapped) Model # GX-1 (ground) • LX-1 Lapped with Mirror Finish. • GX-1 Ground finish for less reflection. • Supplied with Certification and storage box.

GSG QUIKCHEK

GSG QUIKCHEK is used to calibrate Coordinate Measuring Machines (CMM). The QUIKCHEK provides an easy periodic check on the CMM to ensure it is within calibration and providing you with accurate readings. In addition it provides a more volumetric inspection of a CMM than the traditional ball bar. Model 8 Inch Model 16 Inch The QUIKCHEK is your mechanical assurance of CMM accuracy. The QUIKCHEK is 440c stainless steel hardened to Rc 60-62, stress relieved and triple stabilized . Supplied with certification and case. Special sizes available at contact factory.
