Cameron Instruments Inc. operates a state-of-the-art A2LA ISO17025 accredited Calibration Facility. Their laboratory provides high-accuracy pressure and temperature calibrations, using Fluke Piston Gauges and AMETEK JOFRA dry block and liquid bath temperature calibrators.


The Laboratory’s current scope for pressure includes 5kPa (0.7 psia) to 200MPa (30,000 psia) in gauge or absolute mode. Cameron calibrates pressure using two Fluke High-Pressure Controllers and four Deadweight Testers.

The first controller Cameron uses is the Fluke 8370A Modular High-Pressure controller with capabilities to 10,000PSI. The Fluke 8370A is a pneumatic pressure controller that calibrates a wide workload of pressure sensors, covering twice the pressure ranges at twice the speed of other high-pressure controllers.

The second High-Pressure Controller Cameron uses is the Fluke 6270A with calibrating capabilities up to 3000PSI. Together, the two work stations integrate seamlessly with the Fluke Compass for pressure software, providing fully automated calibrations of a wide selection of multiple devises.

Cameron instruments also uses four deadweight testers for pressure calibration. These include the PG 7601, PG 7202 and two Ruska 2465 units.

The PG7601 is a reference device that uses gas to reach pressures of 7kPa to 7MPa (1-1,000psi). This unit covers absolute and gauge pressures including near and under atmospheric pressure, and can establish and measure a vacuum by defining absolute pressures relative to an evacuated bell jar. The 7601 can also utilize a “differential mode” operation to cover positive and negative differential pressures near zero and at different static pressures.

The Fluke 7202 is another gas reference system with the ability to measure a vacuum and a wide range of positive pressure from 100kPa(15psi) all the way up to 110MPa (16,000psi). The PG7202’s gas operated, liquid lubricated design overcomes the disadvantages of lubricating the piston-cylinder with gas at high pressure. Performance is not affected by gas cleanliness and piston drop rates are even lower than typically found in hydraulic piston gauges.

Finally, Cameron uses two Fluke Ruska 2465 deadweight testers. These calibrators provides low-pressure draft calibrations and tighten up specifications and accuracies. When asked about the Ruska 2465 and how it makes calibrations easier, Andreas Stachyra (Laboratory Manager) and Erik Nielsen (Laboratory Administrator) both stated “The compact size of the base and the mass sets take up much less desk space than other models and are easy to store and transport making it easier to calibrate anywhere in the lab”.

Recently, Cameron Instruments became A2LA ISO 17025 accredited for temperature with capabilities between -100°C to +660°C and DC Electrical. To calibrate temperature Cameron uses the JOFRA dry block and liquid bath temperature Calibrators.

Cameron uses the JOFRA CTC660 temperature calibrator for their high temperature calibrations. The Jofra CTC660 features a temperature range between 28°C to 660°C, improved accuracy and dedicated temperature regulator for quick heating and cooling.

The second Temperature Calibrator Cameron uses is the JOFRA RTC159 to achieve the lower range of their scope. The Jofra RTC159 offers a temperature range between -100°C to 155°C. The RTC159 features improved load compensation technology for perfect temperature uniformity and increased heating and cooling time. “A main feature of the RTC159 that makes calibrations easier is the wide temperature range that allows us to test sensors from -100C to 155C using this single dry block instead of needing separate low temperature and high temperature models” stated our Laboratory Administrator Erik Nielsen.

“We would like to see our laboratory grow over the next few years to help the people we service better” Says Lab Manager Andreas Stachyra. With the growing demand of calibrations, Cameron Instruments remains committed to investing in quality products and competency to meet our customer needs.
