PID Analyzers, LLC, provides service as well as customer support for HNU, HNU Systems, Process Analyzers and PID Analyzers' instruments. If you have service questions, need to calibrate your PIDs, GCs, or get annual maintenance and service contracts you may contact us via email or telephone at 774-413-5281 X0.

If you are sending in your unit for cleaning and calibration or repair, please fill out our online Return Authorization (RA) form to make sure that you include all the components needed to diagnose and/or repair your instruments. If you have any questions regarding packaging and shipping address you will find this information there.

When we receive your instrument, we will email you to let you know that it has been received and is in the service queue. This will be followed by a second email providing a repair estimate. The Clean and Calibrate service is $350.00, not including shipping charges. However, replacement parts, if needed, are billed at cost. Additional work will be charged at a rate of $125.00 per hour. No work will be performed until this repair estimate has been approved by you. If the repair estimate is declined we will charge a one time evaluation fee of $150.
