How can Instrument Repair & Calibration help my company?

At Instrument Repair & Calibration, accuracy is one of our top priorities, which is why for more than four decades we have provided our customers with N.I.S.T. traceable calibration services and standards.

We guarantee a seamless process and quality service when helping all of our customers with their test and measurement equipment and calibration requirements.

We use automatic calibration software and verified procedures in order to calibrate with a minimum 4:1 accuracy ratio and comply with ISO 17025. And all test and measurement equipment is either calibrated at our labs in-house, or, for your convenience, on-site, in our mobile calibration lab.

We also offer automatic recall and out of tolerance notifications and before and after calibration service data options. Plus, our customers can keep track of their calibration notifications and data, as well as their instrument's service history, all through Instrument Repair & Calibration's customer portal.

FEATURED CALIBRATION STANDARD:

Pratt & Whitney Measurement Systems Labmaster Universal, Model 175

With instrument uncertainty to 2 millionths of an inch (50 nanometers), the Pratt & Whitney Labmaster Universal - Model 175 is suitable for virtually all Internal (ID), external (OD), and same side dimension (SD*) measuring applications. This laser-based universal length measuring system (ULM) has been developed by Pratt & Whitney for gage calibration laboratories that need to precisely measure length, outside diameter, inside diameter, pitch diameter, lead, major/minor diameter, taper, linear displacement, and thickness.

High accuracy is maintained by its laser interferometer, zero Abbe offset design, and large measuring table (100 lb [45 kg] capacity) with center position, height, pitch, and yaw controls. The computer-controlled precision air bearing slide and gaging probes remove operator-influenced errors commonly observed with traditional gaging methods by maintaining constant force. It also greatly minimizes wear and tear to both the measuring standards and the instrument. The large measuring table also acts as a soak plate. By design, the weight of the part will not affect the measurement because the table support is independent of the air bearing slide. This is not the case with traditional methods.

The ULM is capable of measuring many types of equipment such as gage blocks, end standards, plain rings, threaded rings & plugs, API gages, pin & plug gages, tapered plugs, cylindrical setting gauges, micrometers, indicators, LVDTs, calipers, and snap gauges with instrument uncertainty to 2 millionths of an inch (0.05 micron). It is suitable for virtually all ID and OD gage calibration applications through its wide 0.020-inch (0.5 mm) to 14-inches (356 mm) measuring range. The ULM includes Pratt & Whitney’s GageCal software that automatically enters tolerances for rings, plugs, pins, balls, threads (calculates pitch/major diameter) and flags out of tolerance conditions.

Geometric measuring characteristics related to size include: positional tolerance (on axis), parallelism, perpendicularity, angularity, total runout (pass/fail).
