Cameron Instruments Inc. operates a state-of-the-art pressure calibration facility at our Guelph location. Our lab is focused on high accuracy pressure and temperature standards and we strive to continually improve these standards. Our current capabilities cover the entire pressure range from 5kPa (0.7 psia) to 200 MPa (30,000 psia) in either gauge or absolute mode. Most types of pressure transmitters, calibrators and gauges can be calibrated. Custom calibrations and pressure testing are available to meet your specific requirements. As a customer service provider we concentrate on providing a quick turn-around time for our customers, along with competitive pricing. All standards and calibrations are traceable to National Standards (NIST) and come complete with as-found-as-left data.

All of our calibrations are performed in our Guelph, ON Laboratory.
