Calibration Services in Carson

Pressure instrumentation is the core of the work here

Refining and process operations generate more pressure calibration than anything else we see from Carson: transmitters, pressure gauges, transducers, relief and safety valve test equipment, and the calibrators technicians carry to verify them in the field.

Our pressure laboratory covers −14.7 to 10,000 psi. Pneumatic work runs on a Fluke 7250xi at ±0.005% of reading to 2,500 psi, hydraulic on a 7615 to 10,000 psi, and low pressure on a Ruska 7250LP from 0 to 30 inH₂O at ±0.009% of reading. That low-pressure capability matters more than people expect — draft and differential measurements on stacks and enclosures live down in inches of water, and a lab without that range simply cannot cover them.

Gas flow, and why it is rarer than it should be

Mass flow controllers and flow meters on process gas and emissions systems need periodic verification, and comparatively few regional labs hold accredited gas flow capability. We run Fluke molbloc and molbox reference systems across six laminar flow elements spanning 50 SCCM to 2,500 SLM, at ±0.25% of reading over 10 to 100% of full scale.

Gas flow calibration usually arrives bundled with pressure work from the same plant, which is convenient — one pickup, one certificate package, one recall date rather than a separate specialty supplier for the flow devices.

Port logistics measures in force, torque, and weight

The logistics side of Carson brings a different list. Truck and container operations run scales at every weighing point, torque wrenches through fleet maintenance on wheel and driveline fasteners, force gauges and load cells on lifting and rigging verification, and multimeters across electrical maintenance.

We calibrate torque from 0.5 ozf·in to 1,000 lbf·ft, force by dead weight, and mass against ASTM and OIML Class 1 weights to 25 kg. For scales and equipment that cannot be removed from service, on-site calibration is scheduled roughly two weeks ahead, with after-hours and weekend visits available around turnaround and shutdown windows — which in Carson is frequently the only workable time.

Documentation heavy industry actually gets audited on

Process safety management, environmental reporting, and customer audits all reach back to the same question: was the instrument that produced this number in tolerance, and how do you know. Our certificates document as-found and as-left readings, measurement uncertainty, NIST traceability, and the ANSI/NCSL Z540.3 decision rule with TUR. As-found data is the part that matters when something reads out of tolerance and you have to scope backward through the affected records.

American Gage is ISO/IEC 17025:2017 accredited by A2LA under certificate 4296.01. Carson sits on our free Tuesday and Thursday Los Angeles County route, about 28 miles from the lab. Standard turnaround is 7–10 business days, with expedited 24, 48, and 72-hour service when a unit is down.
