CO-Quick CO Detector

DELIVERS IN 2-3 WEEKS

• 360° visible illuminated enclosure. CO-Quick uses a translucent case with 8 green LEDs and 8 red LEDs so status can be seen from virtually any angle or mounting orientation.

• Analog-style escalating response. Instead of a dead binary feel, CO-Quick visibly comes alive as CO exposure builds. A light red percolation grows toward full red boil, giving users a more intuitive sense that conditions are changing.

• Open, fast-breathing sensor geometry. Generous openings at the sensing end expose the sensor to real ambient air, supporting quick response and quick clear-down.

• Tiny puck form factor. At only 1.25 inches in diameter, 0.85 inches tall, and 11 grams, CO-Quick is easy to place where bulkier detectors do not belong.

• Simple USB-C power. CO-Quick uses a USB-C receptacle for power only and ships with a USB-A to USB-C cable.

• Smart mechanical layout. The flat side mounts naturally to flat surfaces, while the sensing openings are located on the opposite end, where they remain exposed to the surrounding air.

• Status-at-a-Glance. Green means normal. Red means attention. The transition between them is immediate, visible, and hard to miss.

How CO-Quick Indicates

• Normal condition. Steady green illumination.

• CO rising. Red visual activity begins lightly, then intensifies with increasing exposure.

• Full indication. At 100 ppm CO, CO-Quick reaches full red visual indication.

• Fresh air recovery. When returned to clear air, the indication drops back rapidly toward normal.

• Startup behavior. CO-Quick includes an approximately 45-second startup inhibit / stabilization period after power is applied.

• Product name. CO-Quick

• Product type. Visual carbon monoxide detector

• Sensor type. Electrochemical fuel-cell CO sensor

• Sensor model. Saiya SY-CO-28BPE

• Normal indication. Steady green

• CO indication. Progressive red visual alert, escalating from light percolation to full boil

• LED count. 8 green LEDs, 8 red LEDs

• CO-Quick does not have an ambient light sensor. As a result, the LEDS are always illuminated at normal brightness levels. This may make CO-Quick unsuitable for use in dark cockpits.

What’s included

• CO-Quick detector

• USB-A to USB-C power cable

CO-Quick uses an electrochemical CO sensor with linear output and fast response characteristics. The sensor vendor also flags several application cautions that matter in real installations:

• Avoid silicone vapors near the sensing end. That includes silicone-curing adhesives, sealants, silicone rubber, putties, and similar materials near the air path.

• Avoid long-term exposure to organic solvents.

• Avoid acidic or strongly alkaline environments.

• Shock and vibration can damage the sensor element.

• Hydrogen sulfide / corrosive sulfur exposure can damage the sensor, even though the typical cross-response table does not show a false CO reading for H2S at 100 ppm.

• The sensor shows notable cross-sensitivity to ethylene and some cross-sensitivity to hydrogen. Typical vendor data shows:

  • ethylene 100 ppm → about 80 ppm CO equivalent

  • hydrogen 500 ppm → about 40 ppm CO equivalent

  • chlorine 10 ppm → about 1 ppm CO equivalent
