CAT45 - Combustion Analyzer CAT45 - Combustion Analyzer

  • What are the combustion measurements available with the CAT45/CAT85?

    • The Combustion Screen shows up to 8 different simultaneous readings and can be customized to your liking. The CAT45/CAT85 shows the following readings: Stack temp, O2, CO, CO air free, CO2, flue draft, excess air, efficiency, dew point, and flue gas heat loss (qA). To customize the display select [SETTINGS], scroll to “Combustion Setup”, select [EDIT], and then select and place parameters however is preferred.

  • Is it possible to start the CAT45/CAT85 combustion analyzer in the Combustion Analysis screen?

    • Yes, the combustion analyzer can start in the fuel type selection, combustion analysis, or job setup . To start in the Combustion Analysis screen, select [SETTINGS], scroll to [STARTUP SCREEN], press [JOB MENU] to advance to Combustion, press the [JOB MENU] to return to Main Screen. The Analyzer will now start up in the Combustion Analysis screen upon the next power-on.

       

       

  • Do you offer calibration and repair services?

    • Yes, contact Fieldpiece at fpwarranty@fieldpiece.com, fieldpiece.com/rma, or (714) 634-1844 to learn more and schedule repair/calibration.

  • Why is there no water trap with the CAT85?

    • The CAT85 automatically separates and returns water to the flue using the patent-pending HydroCycle™ Pump technology, providing a care-free water collection system.

       

  • How long do the CAT45/CAT85 sensors last?

    • Our SensorVault™ technology extends sensor life by sealing the sensors from oxygen in the air during storage. The field replaceable sensors are warrantied for four years meaning maximum uptime on the job site.

       

       

       

  • Why does the CAT45/CAT85 sometimes turn on by itself when plugging it into power?

    • Our SensorVault™ technology extends sensor life by sealing the sensors from oxygen in the air. during storage. If the combustion analyzer is powered off improperly (for example, the battery runs out while powered on) it is possible for the sensor seal to become out of sync with the power on state. When plugging into a power source the combustion analyzer will check to make sure the sensor sealing is correctly synced with the button, if the analyzer detects the sensor is out of sync the analyzer will automatically power on.
