HOBO^® Carbon Monoxide Logger

Monitor carbon monoxide (CO) levels in areas such as garages, terminals, loading docks, construction sites, furnace rooms, office buildings and living areas. Convenient battery operation eliminates the need to run wires for AC power, making it easy to deploy the HOBO CO logger at various potential hotspots. Use the resulting data to help identify problems with furnaces, vehicles, water heaters, stoves, fireplaces, ventilation, air supplies, and flues (non-condensing environments only). Optimize resolution and accuracy with three software-selectable ranges: 0 to 125 ppm, 0 to 500 ppm, 0 to 2000 ppm (parts per million).

Important: The HOBO Carbon Monoxide logger is a data recording device only. The data logger does not replace the need for safety/warning alarm that alerts personnel when carbon monoxide exposure reaches dangerous levels.

* Battery life is shorter when CO levels average 10 ppm or more. For example, battery life is 6 months at average concentrations of 100 ppm.

Measurement Specifications

Nominal Range (ppm)	Actual Range (ppm)	Resolution (ppm)	Accuracy
0 - 125	0.2 - 124.3	0.5	±1 ppm ±10%
0 - 500	1 - 497.1	2	±3 ppm ±10%
0 - 2000	4 - 1988	8	±5 ppm ±10%

The CO sensor is temperature compensated over the entire operating range; however, very rapid temperature changes can contribute as much as an additional 10% error to the above accuracy specifications.

Physical shocks or rapid changes in ambient pressure may show up as spikes in the data.

Response time: 11 minutes typical, depending on installation location and orientation.
