Frequently Asked Questions

Common questions about Techmaster oil, gas, and petrochemical test equipment services.

Are your cal certs accepted on API-MPMS custody-transfer audits?
Yes. Our ANAB-accredited ISO/IEC 17025 cal certs are accepted by ExxonMobil, Chevron, Shell, BP, Marathon, Phillips 66, and Valero custody-transfer measurement teams — with traceability documented to API MPMS Chapter 4 / 11 / 14 requirements.
Do you support on-site portable gas detector bump testing?
Yes. Our field engineers perform bump testing and full span calibration of Industrial Scientific, RAE Systems, Honeywell BW, and MSA Altair gas detectors with NIST-traceable cylinder gases (LEL, H2S, CO, O2, VOC) per OSHA / ISEA RP 12-2.3.
Can you support refinery process-loop calibration with documenting calibrators?
Yes. Our engineers carry Beamex MC6 / MC2 documenting calibrators, Fluke 754, and Druck DPI 612 / 620 pressure calibrators for on-site refinery loop verification — with full uncertainty budgets and 21 CFR 11-aligned electronic records.
Do you handle Class I Division / Zone hazardous-area instruments?
Yes. Hazardous-area instrument intake is supported with proper segregation and intrinsic-safety verification. Our quality program documents transit conditions and certification per NEC / IEC ATEX / IECEx as required.
Which Techmaster locations serve oil-and-gas customers?
San Antonio TX (Houston / Permian Basin proximity), Orlando FL (Gulf-Coast refineries), Vista CA, and Santa Clara CA. On-site CONUS for offshore platform and remote-site cal campaigns.
