Certified Technicians

At HPI, we take equipment testing and calibration seriously. That's why we employ technicians who are not only certified by the Controlled Environment Testing Association (CETA), but are also accredited by the NSF49. This means that you can trust our technicians to expertly test, calibrate, and certify your equipment to meet the highest standards, in accordance with the IEST RP CC-002 and CETA CAG-003.

In addition to our equipment testing and calibration services, we also offer warranty and non-warranty repairs. Our service technicians are fully trained and certified to perform these repairs, so you can be confident that your equipment is in good hands. Whether you need routine maintenance or major repairs, our team will work quickly and efficiently to get your equipment back up and running as soon as possible.

Testing Equipment

At HPI, we understand that the precision and reliability of calibration services are contingent upon the testing equipment used for certification. For this reason, we ensure that all our testing equipment is calibrated on an annual basis and NIST traceable. We take pride in our commitment to quality standards and strive to ensure that our services meet or exceed industry benchmarks.

We value your time and understand the importance of timely reporting. Our reports contain all certification data and will be sent the same week the work was completed.

How often should a Laminar Airflow Workstation be certified?

• A Horizontal or Vertical LAFW should be certified at least once a year.
