Fluke CO-220 Carbon Monoxide Meter Repair

The Fluke CO-220 is a handheld carbon monoxide meter — it measures ambient CO concentration (ppm) with an electrochemical sensor for HVAC, combustion, and indoor-air-quality work. Its accuracy depends on the electrochemical CO sensor and the measurement electronics, which is where repair and calibration focus.

FlukeMeterRepair.com repairs and calibrates the Fluke CO-220 for HVAC technicians, building-commissioning agents, and IAQ specialists.

Common Fluke CO-220 problems we fix

• CO-sensor degradation — an aged or contaminated electrochemical sensor giving inaccurate readings, replaced and recalibrated against standards.
• Display failures — missing segments or a dim display, repaired.
• Measurement / zeroing faults — the meter not zeroing or reading correctly, repaired.
• Battery or housing faults — repaired.
• Won’t power on — power faults.

FAQs

My CO-220 reads CO wrong — fixable? Yes. Sensor and electronics faults are repairable, then the meter is recalibrated so CO readings are accurate, with a NIST-traceable certificate.

Is the sensor verified? Yes — checked against our calibration gas standards.

Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
