ISO/IEC 17025:2017 calibration · Valid through April 30, 2027
The industrial cal vendor most plants settle for
Most refineries, petrochem plants, and industrial sites end up with a calibration arrangement that's better than no calibration but worse than what's actually possible. The big national vendors send a different technician each visit, can't move on a shutdown timeline, and ship anything interesting back to a regional lab three states away. The local cal shop has the right relationships but isn't A2LA-accredited and can't sign a 17025 certificate. So you end up with one vendor doing the easy stuff onsite and another vendor doing the rest by ship-in.
Allometrics built around the opposite premise. Founded in 1976 in Webster, TX — a 25-minute drive from the Houston Ship Channel — we maintain an A2LA-accredited bench investment large enough to keep most scope and DC power supply work in-house and onsite, plus the field-service crew capacity to mobilize multi-tech teams during plant turnaround windows. The same crew that calibrates an instrument tech's tool pouch can drop loops, verify pressure references on a 10,000 PSI gauge, recertify a refinery's scale-trade-cert program, and certify a chemical plant's chemistry lab dimensional set — all under one A2LA accreditation chain.
Long-running relationships with refineries on the Houston Ship Channel and in the Beaumont / Port Arthur corridor, polymer plants in Texas City and Pasadena, food & beverage operators across the Gulf Coast, aerospace and defense MRO operators, and the automotive QA programs that run permanent onsite calibration on bolted-down fixtures.

Why industrial operators consolidate with Allometrics
One A2LA scope across the entire instrument pouch. The same accredited certificate format covers your electrical bench, your process loop calibrators, your pressure dead-weight tester, your scale, your micrometers, and your plant chemistry lab analytical instruments. Most cal vendors specialize in one or two of these — we run all of them under Cert 2039.01.
Onsite-capable for the work other labs ship out. Our $80,000 electrical bench investment means most oscilloscopes and DC power supplies stay onsite rather than ship-in. Mass & dimensional work travels with our gauge block and reference standards. Pressure work uses our portable dead-weight standards. Multi-tech crews mobilize for plant turnaround windows.
Safety-trained for live plant environments. Internal Electrical & Electronic Calibration Safety course covering IEC 61010, NFPA 70E (arc-flash and electrical safe work practices), and OSHA 1910 high-voltage rules. PPE, lockout/tagout, and CAT II/III/IV-rated test leads — built into the job plan, not improvised.
Fail-and-respond service. When a critical loop fails calibration mid-shift, call (281) 474-3329 and we'll dispatch. Recurring annual program customers get priority response.
Audit-time guarantee. If a calibration we delivered is challenged in a customer audit, ISO 9001 surveillance, AS9100, IATF 16949, API Q1/Q2, or state weights & measures audit, we will address it. Records on IndySoft — 21 CFR Part 11–compliant electronic records.
50 years of regulated and industrial experience. Founded 1976. 1,800+ accounts. Continuous through every major refinery turnaround cycle on the Texas Gulf Coast.
