Frequently Asked Questions
What types of load measuring equipment does Holloway Houston service?
We service a wide array of equipment, including tension and compression load cells, load shackles, running line tensiometers, hydraulic jacks, PSI gauges, and various industrial scales. We also service equipment from top brands like Crosby, Green Pin, and Straightpoint.
How often should my equipment be calibrated?
The frequency of calibration depends on the manufacturer's recommendations, industry standards (such as ASME), and the frequency of equipment use. For equipment in heavy or severe service, more frequent calibration is often required. We can help you establish a calibration schedule that meets your operational needs and ensures compliance.
What is the calibration process at Holloway Houston?
For smaller items, you can send them to our state-of-the-art facility. Upon arrival, our technicians perform an initial inspection, conduct the calibration using our computerized test beds against NIST-traceable standards, and generate a detailed certification report. For larger equipment, we can dispatch our team to your site to perform on-site calibration.
What certifications are involved in calibration?
Our calibration services are NIST-certified, meaning they are traceable to the standards maintained by the National Institute of Standards and Technology. We adhere to ISO 9001 quality management systems and follow the technical requirements of standards like ASTM E4-21. This provides you with the documentation needed to meet regulatory requirements.
