Items for Repair

Fieldpiece recommends that the CAT45 and CAT85 Combustion Analyzers be calibrated every 12 months. Two affordable calibration options are available for your convenience.

System Preventative Maintenance and Calibration:
This comprehensive service provides calibration and verification of all measurement sensors including temperature sensors, pressure sensors, CO sensor, and O2 sensor. Also included is an external cleaning of the unit and probe and verification of system operation. For this service you will send the CAT45 or CAT85 system and the probe.
Once an RMA is issued, the product should be shipped freight prepaid and packaged appropriately. Fieldpiece will return the product at the same freight service level as received at no charge to you.

Sensor Calibration:
