Tech Cal has been providing calibration services in Houston since 1984. As an ISO/IEC 17025-accredited calibration lab, we follow the international standard for calibration laboratories and deliver accurate, NIST-traceable results for industrial instruments, including pressure gauges, pressure transducers, torque wrenches, load cells, and chart recorders.
Have your equipment calibrated fast. Turnaround time is typically 3 to 5 days. Rush/expedited service (24-hour turnaround available upon request).
Our calibration lab in Houston is equipped to handle selected mechanical and industrial instruments. All calibrations are performed to NIST-traceable standards by experienced technicians who understand the demands of industrial environments.
We calibrate digital and analog pressure gauges, compound gauges, high-pressure gauges, vacuum gauges, pressure transducers, and differential pressure instruments. Whether you need a single gauge or a scheduled batch calibration for your facility, our team provides accurate, documented results with full traceability.
Tech Cal is one of Houston’s most experienced providers of chart recorder calibration. We calibrate mechanical and electronic chart recorders used in oil and gas, pipeline, and industrial process applications. As the manufacturer of Tech Cal Chart Recorders, our technicians have an in-depth understanding of recorder mechanics and performance that most calibration labs simply cannot match.
We calibrate torque wrenches to NIST-traceable standards. Accurate torque measurement is critical in pipeline, petrochemical, and manufacturing environments where fastener integrity directly affects safety and compliance.
Our lab provides load cell calibration for industrial and manufacturing applications requiring accurate force measurement and documented traceability. We support the accuracy and traceability requirements expected in regulated environments, providing calibration certificates suitable for audit and compliance purposes.
Tech Cal holds ISO/IEC 17025 accreditation, the international standard for calibration laboratories. Our quality management system, equipment, and procedures have been independently assessed and meet the requirements for technical competence and measurement traceability. For customers in regulated industries, this means your calibration certificates carry verified international validity.
With over 40 years of experience serving Houston’s oil and gas, petrochemical, pipeline, and manufacturing sectors, Tech Cal has built a reputation for reliability, accuracy, and industry knowledge.
Our long-standing technicians bring deep expertise to every instrument we service — knowledge that only comes from decades of hands-on work with the equipment your operations depend on.
Standard turnaround for most calibrations is 3 to 5 business days from receipt of your equipment. For urgent requirements, we offer rush and expedited 24-hour calibration service upon request.
Tech Cal’s skilled technicians are equipped with innovative test equipment certified to NIST-traceable standards to ensure the highest accuracy for our customers’ products.
Tech Cal operates and maintains a cutting-edge calibration lab that is monitored daily to maintain appropriate environmental conditions and limits. Temperature conditions are maintained at 72 degrees F +/- 4 degrees, with a relative humidity of 65% or less.
