Frequently Asked Questions
Common questions about ISO/IEC 17025 thermodynamic calibration — temperature, humidity, pressure, and thermal mapping — at Techmaster Electronics.
What temperature and pressure standards does Techmaster calibrate to?
We calibrate temperature, humidity, and pressure instruments traceable to NIST via the ITS-90 temperature scale (triple points of water and metal fixed points), saturated-salt humidity standards, and deadweight-tester pressure standards. Methods follow ASTM E220, ASTM E77, AMS 2750, USP <1079>, ISO 17025, and DKD-R 6 / EURAMET cg-13 procedures.
Is thermodynamic calibration accredited to ISO/IEC 17025:2017?
Yes. Techmaster Electronics is ANAB-accredited to ISO/IEC 17025:2017 (Certificate AC-1736) covering temperature, humidity, and pressure parameters at our Vista, Santa Clara, and Orlando laboratories. Every accredited certificate includes calibration uncertainties, the ANAB logo, and full NIST traceability.
How often should temperature calibrators and reference thermometers be recalibrated?
Annual recalibration is the standard cycle for dry-block calibrators, reference thermometers, pressure calibrators, and IR pyrometers. High-stakes processes (pharma freezers, AMS 2750 furnaces, autoclaves) often require 6-month intervals. AS9100 / IATF 16949 customers receive uncertainty budgets sized for their tolerance limits.
Do you perform on-site thermal mapping or temperature surveys?
Yes. We perform on-site temperature mapping for warehouses, lyophilizers, autoclaves, freezers, and stability chambers per USP <1079> and AMS 2750. Our engineers travel with calibrated dataloggers and reference thermometers; deliverables include IQ/OQ/PQ documentation and a NIST-traceable certificate.
Where do you perform thermodynamic calibration?
In-lab temperature, humidity, and pressure calibration is performed at our Vista CA (corporate HQ), Santa Clara CA, Orlando FL, and San Antonio TX facilities. Free local pickup and delivery is available in Silicon Valley, Southern California, and Orlando. On-site thermal mapping is available throughout the continental United States.
