Through calibration, we verify and, if necessary, adjust instruments to conform to the manufacturer’s specifications. A label is affixed to the instrument with the new calibration date and the next expiration date, and a calibration report is provided without data.

The calibration certificate includes a calibration with a report on the comparison data, and the previous measurements are written on the certificate.

All the calibration certificates we issue are referenced since our calibrations are certified and referenced to NIST or CNRC, as prescribed in our quality manual.

Our calibration laboratory operates in accordance with ISO 17025:2017. SCC Accredited Laboratory; NRC CLAS 2016-01 Certificate.

We are also able to calibrate your instruments IN THE FACTORY with the following specialties:

  • Calibration of thermometers or graphic recorders in cold rooms.
  • Calibration of industrial or sanitary pressure gauges from vacuum to 16,000 psig.
  • Calibration of pressure gauges and differential transmitters from 0 to 60 in. H2
  • Calibration of hygrometers or transmitters compared to a certified hygrometer.
  • Calibration of thermostats, temperature controllers with or without probe.
  • Calibration of temperature probes: Thermocouple, thermistor or RTD, from -20 to 600°C.
