Calibration discipline

What is Pressure calibration?

Quick answer

Pressure calibration determines the error of gauge, absolute, differential and vacuum instruments — pressure gauges, transmitters, digital pressure indicators. Techmaster’s ISO/IEC 17025:2017 lab is traceable to the SI pascal (Pa).

Pressure is critical in oil & gas, chemicals, food, pharma and boilers — where measurement error can cause safety hazards or process drift. Periodic calibration ensures operational safety and standards compliance.

Techmaster calibrates pressure with deadweight testers (pressure balances) and digital pressure standards, traceable to the pascal; aligned with DKD-R 6-1 and international guidance for pressure-gauge calibration.

Measurement range

Typical measurement ranges & CMC

The table below lists typical parameters & measurement ranges for this discipline.

Parameter / Instrument Typical measurement range CMC / Measurement uncertainty
Gauge 0 – 700 bar (up to 1000 bar) [Verify against scope]
Vacuum −1 – 0 bar [Verify against scope]
Low pressure 0 – 100 mbar [Verify against scope]
Differential 0 – 10 bar [Verify against scope]
Safety valve per working range [Verify against scope]

Note: The ranges & CMC below are typical reference values. Please verify against Techmaster’s official Scope of Accreditation before publishing — actual CMC depends on the reference standard, method and measurement conditions.

Standards & traceability

Reference standards & traceability

Pressure is traceable to the SI pascal (Pa) through certified pressure balances (deadweight testers) and digital pressure standards; referencing the DKD-R 6-1 / EURAMET cg-17 guides.

Q & A

Frequently asked questions

What pressure ranges can Techmaster handle? +
From vacuum up to high pressure (hundreds of bar), including gauge, absolute and differential. Contact us to confirm the exact range per our scope.
Do you calibrate 4–20 mA pressure transmitters? +
Yes. Techmaster calibrates pressure transmitters on pressure-to-current (4–20 mA) or pressure-to-voltage outputs, with full-span error assessment.
Should safety valves have set-pressure testing? +
Yes. Verifying safety-valve set pressure is vital for pressure-system safety; Techmaster supports this within scope and equipment limits.
Is on-site pressure calibration accurate? +
With calibrated portable digital pressure standards, on-site work is fully reliable; higher-accuracy items can be done in the lab.
