Practical Instrument

History

PIE's official 2025 catalog says its engineers have designed calibrators since the 1980s and have designed them for PIE since 2001. That wording documents substantial product-line experience but does not conclusively establish either the corporation's incorporation year or a single founding date, so this draft does not convert 2001 into a structured founded-year claim. The catalog says the instruments are designed and assembled in Webster, New York, using components sourced globally.

The manuals in this collection cover instruments such as the 311PLUS, 510 and 511, 522, and 525 series. Official datasheets and field-calibration procedures show the practical scope behind those model numbers: sourcing and reading process signals, simulating thermocouples and resistance sensors, checking transmitters, recorders, controllers and alarms, and maintaining the calibrators themselves. The reviewed current catalog demonstrates an active product range, while the structured headquarters field is omitted because the source presents a current business and service address rather than explicitly labeling it a headquarters.
