What was not measured
The laboratory page does not name a pressure gauge. It says a public fee schedule establishes fees, and that local, state, and federal government agencies are exempt from fee payments. This page does not copy a dollar amount from that schedule, and it does not state a turnaround.

Pages with their own source
The rule for gas-utility pressure gauges is a separate page. A facility in Pennsylvania can still send a request when it has no page of its own.
Questions the laboratory page can answer
Its page lists traceable calibrations for mass, volume, length, time, and force. The force line is push-pull gauges by tension up to 30 lbf. A pressure gauge is not named.
