Skip the quote requests, emails, and waiting. Enter your instrument, pick a turnaround, pay online, and print your RMA label immediately. NIST-traceable calibration for pressure gauges, sensors, and switches — plus temperature transmitters, indicators, and loop instruments.
Traditional calibration labs make you request a quote, wait for a reply, arrange payment, and then wait again for an RMA number. We collapsed all of that into one online checkout.
Vacuum to 10,000 psi, NIST-traceable, with digital certificates on every job — plus temperature transmitters, indicators, switches, and full loop calibration with HART.
Analog dial gauges — vacuum to 10,000 psi. As-found / as-left data and free zero adjustment on every certificate.
Transducers and transmitters with mV, V, or mA output. Multi-point up and down calibration.
Setpoint and deadband verification — setpoint adjustment always included.
Digital gauges and indicators, including high-accuracy test gauges.
DP gauges, transmitters, and indicators — low DP ranges a specialty.
RTD/TC-input transmitters (Rosemount 644/3144P, Yokogawa YTA, and more). HART configuration & trim included.
Panel meters, readouts, recorders, temperature switches, and PLC/DCS analog-input channels (from $35/channel).
End-to-end 4-20 mA loop verification with HART communication — sensor simulation in, control-system reading out.
RTD/TC probes & dial thermometers (temperature source arriving), ISO/IEC 17025 accredited calibration, on-site service.
Everything happens online — ordering, payment, RMA, tracking, and certificate delivery.
Select instrument type, enter manufacturer, model, range, and quantity. Answer a couple of quick questions.
Transparent pricing calculated on the spot. Choose standard, expedited, or rush turnaround. Pay by card.
Your RMA number and packing slip generate immediately. Box it up and ship to our lab the same day.
Follow status online. Certificates are delivered digitally and your instrument ships back on time.
Base prices below. Range, accuracy class, and turnaround adjust the final price, which you'll always see before paying.

| Adjust-if-needed add-on | Zero & span adjustment if out of tolerance — auto-refunded if unused | +$30–60 |
Volume discounts apply automatically: 5% off 5+ units, 10% off 10+ units. Ranges above 5,000 psi (+$20) and high-accuracy classes (+$25) carry a small adder — shown instantly in checkout. If you prepay "adjust if needed" and your instrument arrives in tolerance, the adjustment fee is automatically refunded.
Every calibration is performed against reference standards traceable to NIST, with uncertainty ratios appropriate to your instrument.
As-found / as-left data, environmental conditions, and standards used — delivered as a PDF the moment your job completes.
