Each service is performed against documented procedures and national/international standards, with instruments traceable through the NABL chain. Expanded uncertainties are reported at k = 2 (≈95% confidence).
Our largest accredited group — covering basic measuring instruments, gauges and precision instruments measured on length-measuring machines, comparators, VMM and electronic probes.
Hydraulic and pneumatic pressure indicating devices calibrated against digital pressure indicators and comparator pumps per DKD-R 6-1, including vacuum.
Torque wrenches Type I & II across all classes (A–G), torque tools, screwdrivers and meters — calibrated on an electronic torque wrench tester per ISO 6789-1:2017.
Pneumatic, electric, hydraulic and oil-pulse torque tools and torque-controlled DC nut runners — calibrated on a pneumatic rotary torque tool calibration system with torque sensor per ISO 5393:2017, in the clockwise direction. Available in the lab and on site.
Mobile force measuring systems calibrated on a force calibration fixture with stainless-steel Newton weights and loading hangers, by comparison method per VDI/VDE 2624.
Electronic balances and weighing scales calibrated against E2 and F1 class weights per OIML R 76-1, and standard weights calibrated by the substitution method (ABBA cycle) per OIML R 111.
Air-velocity and flow measuring devices calibrated against a wind tunnel calibrator and pitot static tube with digital indicator, plus contact & non-contact tachometers against RPM source calibrators.
Kinematic viscosity of flow cups determined by timed efflux against a Newtonian reference liquid of known viscosity, using a certified reference standard and stopwatch per IS 3944:2020, ASTM D 1200 and ISO 2431.
Shore hardness testers calibrated by the depth-indentation method using an electronic probe with digital comparator tester per ISO 48-9:2018.
Through trusted partner laboratories we also coordinate electro-technical and thermal calibration, so you can consolidate your instrument fleet with a single point of contact.
Electrical & thermal are offered as third-party coordinated calibration.
For instruments that can't leave your floor — surface plates, large balances, pressure lines, height gauges, VMM, profile projectors — our engineers come to you with accredited site facility methods.
