Ever stopped to think about the importance of instrument calibration in our everyday lives? The accuracy of ordinary equipment and instrumentation like scales, fuel pumps, and water, gas, and electric meters is hugely important to manufacturers, everyday consumers, and even the government.

At Madrid’s only approved metrology laboratory, the Opto 22 SNAP PAC System controls equipment used to test, calibrate, and certify domestic and industrial gas meters. The control system is used in test stations to execute very detailed procedures in order to confirm that the meter manufacturer’s accuracy and specifications are correct. In doing so, the system regulates variable speed controllers and solenoid valves, interfaces to printers and barcode readers, records temperatures, adjusts pressures, counts pulses, and logs all test procedure data.
