Find and fix them with PIE calibration solutions
PIE is more than the company that makes calibrators. PIE is the place you can turn to when you are trying to solve problems in your plant! Other companies make calibrators and other test equipment - PIE makes troubleshooting tools to find and solve plant problems.
Our engineers have decades of experience in calibration issues and have most likely helped technicians with a similar problem in the past. We don’t have all the answers, but we do know many others in the industry. Many of our representatives have experience with temperature and pressure measurement, valve design, controller setup and SCADA systems. Some of the companies we partner with are experts in PLC and controller programming. We can also provide training on a variety of calibration, control and instrumentation systems.

You may buy a calibrator from your local distributor, a national distributor or directly from PIE. Your local distributor may provide you with local support including demonstrating the calibrator at your location, delivery services and training. National distributors may provide you with fast delivery options and may have special pricing setup with your company. Calibrators ordered directly from piecal.com must be paid for in advance using PayPal. UPS ground is included at no extra charge and expedited shipping is available. Standard delivery from PIE is 1 to 2 weeks. International shipping will be by UPS with the cost calculated by PayPal.
Every PIE calibrator comes from our factory with a small Calibration Certificate card. It includes the model and serial number, a technician’s signature and the date of calibration. All the assets used for calibration are traceable to NIST. If you require a certificate containing data recorded at multiple points along with a list of the assets and their calibration dates, you should order certified test data at the time the calibrator is ordered from the distributor or from PIE. There is an extra charge for this certified test data.
Absolutely! Our headquarters are in Webster, NY, a suburb of Rochester, NY on the shore of Lake Ontario. PIE calibrators are designed, assembled, calibrated with NIST traceability, and serviced in the U.S. with components that are sourced from around the world.
