We at Greystone Energy Systems are committed to producing a quality product and ensuring customer satisfaction. As a company with a quality system registered to ISO 9002, we take quality very seriously.

At Greystone Energy Systems, we follow documented procedures for the maintenance and calibration of all of our inspection, measuring and test equipment. This allows us to maintain confidence in the products we build, and ensures the utmost accuracy in all finished products.

All meters and gauges used at Greystone Energy Systems are verified and calibrated at regular intervals. The frequency of use determines the schedule. Most meters and gauges are calibrated annually as a minimum, and the remainder varies from every three months to every six months. Published manufacturer specifications are used in the calibration process to ensure calibration accuracy.

Meters and gauges are either verified in house by Greystone Energy Systems Engineering department, or subcontracted out to reputable companies such as Pylon Atlantic and Guildline.

All inspection, measuring and test equipment that is acceptable for use is marked with a TESTED or CALIBRATED label that indicates the date the test was performed and when it is due again. This allows our employees to quickly determine the status of all equipment before use, ensuring reliable readings.

All inspection, measuring and test equipment is safeguarded from adjustments that would invalidate the calibration setting. Safeguards include pot sealing and labels that invalidate calibration if broken or removed.

When new equipment is purchased, it must have a valid calibration certificate traceable to NIST. A valid calibrated label must also be present.

Records of equipment type, identification number, locations, frequency of tests, test results, and procedures for verification / calibration is maintained at Greystone Energy Systems. This enables us to ensure all equipment is tested and calibrated at the required intervals, and to the correct specifications.

All machinery used by Greystone Energy Systems is on a maintenance schedule to ensure proper performance, prompt customer delivery and to eliminate the possibility of breakdowns and shutdowns. Preventive maintenance is performed in accordance with the documented manufacturer guidelines, which varies from every three months to annually, depending on the machine and usage.

Machine operators keep logs of machinery use, to inform our Engineering department when further maintenance is required and if the frequency of maintenance requires adjustment because at Greystone Energy Systems we take our commitment to quality very seriously.
