Why is it important to calibrate your combustion analyzer?
Calibration of your combustion analyzer is crucial to ensure accurate readings and ultimately, safe heating appliance operation. Combustion analyzers measure critical parameters like oxygen (O2), carbon monoxide (CO), and combustion efficiency to help HVAC pros assess the performance of heating systems. Over time, sensors can drift due to exposure to gases, dust, and other contaminants, which can lead to inaccurate readings.
Without proper calibration, an analyzer might give false readings that could either falsely indicate that a system is operating within safe limits or fail to detect hazardous levels of CO. Inaccurate readings could also result in suboptimal efficiency adjustments, increased energy costs for customers or even cause equipment damage. In some extreme cases, incorrect calibration can lead to serious safety risks, including carbon monoxide poisoning. This is why regular calibration is not just a good idea—it’s essential.
Is combustion analyzer calibration mandated in certain regions?
Yes, in some cases, local jurisdictions have their own requirements for calibration frequency and documentation to comply with safety codes and emission standards. These rules can vary by country, state, or even municipality, and some locations may require proof of calibration to ensure that analyzers are providing accurate data, especially when used in industrial or commercial settings.
For example, certain safety authorities and organizations, like the Environmental Protection Agency (EPA) in the U.S. or other local building code authorities, may mandate that all combustion analyzers be calibrated annually and used in their certified state. It’s a good idea to check with your local HVAC or safety authority to determine what specific calibration requirements apply in your region.
How often do you need to calibrate your combustion analyzer?
The general recommendation is to calibrate your combustion analyzer annually, though some manufacturers might recommend more frequent calibration depending on use. Heavy usage in harsh environments, or frequent exposure to high concentrations of gases, may require more frequent calibration to maintain accuracy.
Annual calibration helps to ensure that the sensors remain accurate and that any drift in the readings is corrected. Fieldpiece combustion analyzers, like the CAT45 and CAT85, are equipped with long-life sensors, backed by a 4-year warranty, but you will still need to comply with regional calibration frequency requirements.
Does field-swapping the sensors mean it’s calibrated?
The answer to this will depend on the product manufacturer. In some cases, new sensors may need to be 3rd party calibrated to ensure they align with the analyzer’s electronics and software. However, the Fieldpiece CAT45 and CAT85 field-replaceable sensors are plug-and-play, sealed and pre-calibrated for the device. If you don’t need a 3rd party calibration certificate, replacing the sensors may be the fastest solution, but not the most economical.
Where can I get my Fieldpiece CAT45/CAT85 calibrated?
If you’re using a Fieldpiece CAT45 or CAT85 combustion analyzer, the best option is to send your analyzer to a Fieldpiece-authorized calibration center. Fieldpiece partners with certified facilities that are equipped to calibrate your analyzer according to factory standards. Centers will calibrate the O2 sensor, the CO sensor, verify temperature measurements, update firmware if required and provide a certificate of calibration. You can locate authorized calibration centers through the Fieldpiece website or by contacting customer support (714-634-1844).
Regular calibration of your combustion analyzer is key to maintaining safety, accuracy, and efficiency when installing and servicing combustion heating appliances. By following the manufacturer’s guidelines and getting your analyzer calibrated annually, you’ll ensure reliable readings and avoid potential hazards. Whether you’re using the CAT45 or CAT85, keep your tools up to standard by using authorized services to maintain peak performance year-round!
