Calibration Profile

THE ELECTRICAL CALIBRATION PROCESS

Formonix has individual documented procedures that are followed for each make and model of devices receiving electrical calibration services to insure standardized testing. Equipment manufacturer “accuracies”, generally stated as a percentage of the measured value, have been written into each procedure. Fluke equipment and MET/CAL software provide automated calibration and recording of results. Calibration Certifications are generated directly from the Fluke MET/CAL database for accurate reporting of results. Electronic calibration of equipment that reads AC/DC voltage, AC/DC amperage, frequency, resistance and capacitance is performed using a Fluke. The electrical calibration technicians work with a Fluke for instruments that output AC/DC voltage, AC/DC amperage, frequency and resistance.

Formonix provides Flow Calibration services through an approved supplier in our local area. Our supplier’s capabilities include service for a variety of flow instruments including flow meter calibration, anemometer calibration, hydrometer calibration and more. For one-source convenience, we are happy to coordinate subcontracting of flow calibration orders for our customers who also purchase other calibration or materials testing services provided by our laboratory. To save time on orders that require the services of an outside vendor, please include a note on your purchase order giving Formonix Lab permission to “subcontract your order”.

APPROVED SUPPLIER CAPABILITIES

CALIBRATION SERVICES PERFORMED AT Formonix Lab AND ON SITE

In addition to subcontracted flow calibration, Formonix provides a full line of accredited, ISO 17025 certified and NABL traceable calibration services for dimensional hand tools, masters and pressure, RPM, torque, force, electrical, temperature, mass, humidity and vacuum measuring instruments. Our on-site calibration service covers equipment used at many businesses. Find out more about the array of instruments calibrated by the technicians working on-site and in our state-of-the-art calibration laboratory by reviewing our list of Calibration Services & Instruments Calibrated. A Calibration Certificate is provided for each item calibrated with full details of the work performed. When your instruments are due for re-calibration, we send out reminder notices.

Formonix Lab CAPABILITIES

Formonix Lab calibrates many pressure measuring instruments on-site up to 600 PSI. If your facility has a pressure source, we can go up to 1,500 PSI. Request a quote for service today.

THE PRESSURE CALIBRATION PROCESS

Computerized pressure modules with capacities from vacuum to 40,000 PSI are used to perform pressure calibration services and record the readings. Based on the measurement range of the instrument undergoing calibration, one of Formonix Lab six pressure modules will be selected for the inspection. It is customary to exercise the instrument to its full capacity three times before beginning calibration. As with most calibrations, a standard with a known value or capacity is compared to the instrument being calibrated during the pressure calibration process. Most instruments undergo a 5 point pressure calibration, whereby the inspection occurs at every 20 percent of capacity. A higher accuracy pressure transducer or pressure gauge calibration will include 10 inspection points at every 10 percent of capacity.

MORE THAN CALIBRATION

Pressure calibration is just one of the many calibration services provided by our one-stop laboratory. For a detailed look at our calibration capabilities, refer to our list of Calibration Services & Instruments Calibrated. Working with reliable instruments is essential for efficiency, quality and safety. Let Formonix Lab keep all your instruments in top condition.

SCOPE OF TEMPERATURE CALIBRATION

Formonix can perform temperature calibration on a wide-range of devices, from portable temperature-measuring instruments to large ovens and furnaces. The Lab has dry-wells and liquid-baths with temperature ranges from -45° C to 700°. Temperature Uniformity Surveys are conveniently performed onsite requirements. Technicians take temperature readings at various locations within the oven or furnace to accurately assess temperature consistency and adjustments can be made as needed.

THE TEMPERATURE CALIBRATION PROCESS

Formonix Lab utilizes a number of different processes to perform temperature calibration on a wide-range of instruments both in our lab and in the field. Digital recorder and thermometer calibration takes place on a Fluke multi-process calibrator that runs a Met/Cal software suite for multi-product Fluke calibration. This Fluke calibration system is first programmed with the appropriate inspection temperatures. Temperature readings are then taken from the test instruments and compared with the programmed output to determine their accuracy. Any difference between the actual temperature and the reading indicated is noted. Pyrometer calibration, thermocouple calibration and some recorder and thermometer calibration services are completed using dry-wells and liquid-baths with temperature ranges from -45° C to 1200° C. The liquid in temperature baths and atmosphere in dry wells/blocks are set to a specific temperature for calibration. Once the appropriate temperature is reached, the test instrument and a standard are placed into the bath or well for a comparison of readings. Surface probes and some thermometers are calibrated on special hot plates. Temperature calibration is usually a 5 point inspection, unless more inspection points are requested by the customer

Formonix CAPABILITIES

Vacuum calibration customers receive a detailed Calibration Certificate for each item calibrated that lists “as received” data, complete calibration results, information about any adjustments or repairs made during calibration and NABL traceability.

THE VACUUM CALIBRATION PROCESS

Computerized pressure modules with negative pressure capacities are utilized to perform the inspection and record the results of vacuum calibration. Before the process begins, instruments are exercised to full capacity three times to be sure they are in working order. During the vacuum calibration process, a known standard is set to each pressure point that is inspected and compared with the readings received from the instrument being calibrated. This identifies any deviation from the standard. Instruments typically receive a 5 point vacuum calibration with comparisons to the standard capacity. A higher accuracy calibration will include 10 inspection points at every 10 percent of capacity.
