Calibration Services
In-House NIST-Traceable Calibration
for the Gulf Coast Industrial Sector
At E&S Tool & Calibration Services, we operate a fully equipped in-house calibration laboratory in Pasadena, TX — serving refineries, pipeline contractors, mechanical contractors, and industrial facilities across the Greater Houston area, Gulf Coast, and Louisiana.
Every calibration we perform is NIST-traceable, documented with as-found and as-left data, and issued with a calibration certificate compliant with ISO/IEC 17025 guidelines. We calibrate torque tools, pressure gauges, and dimensional instruments — covering the full range of equipment your operation depends on.
Three Core Calibration Disciplines
Select a discipline to explore our full range of calibration capabilities and sub-services
Torque Calibration
Up to 50,000 ft-lb (67,790 Nm)Mechanical, hydraulic, pneumatic, and electric/battery torque tools — all types calibrated with multi-point verification, CW/CCW testing, and full NIST-traceable documentation.
Pressure Calibration
Vacuum to 15,000 psi (1,034 bar)Industrial, process, and digital pressure gauges calibrated using deadweight testers and precision controllers — rising and falling pressure cycles with full hysteresis and repeatability data.
Dimensional Calibration
All Types — Up to 48"Micrometers, calipers, dial indicators, levels, weld gauges, and more — verified against certified gage blocks and length standards with upstroke and downstroke testing for backlash detection.

Simple, Transparent & Fully Documented
Every calibration follows our structured in-house procedure — from intake to certificate delivery
Receive & Log
Drop off or ship your instruments to our Pasadena facility. Every item is logged into our system and assigned a work order for full traceability.
Calibrate & Verify
Our certified technicians perform multi-point calibration using NIST-traceable reference standards. As-found and as-left readings are recorded at every test point.
Certify & Return
A full calibration certificate is issued with all measurement data, environmental conditions, and uncertainty information. Your instrument is returned ready for service.
Calibration You Can Trust.
Documentation You Can Use.
All calibrations performed by E&S are traceable to NIST and conducted in accordance with nationally and internationally recognized standards. Every certificate is formatted and documented to support your quality management system, regulatory compliance, and audit requirements.
