Portable propane heaters used on a construction site at the Shedd Aquarium in Chicago were generating huge quantities of CO2, causing problems throughout the rest of the building. The contractor denied that the open-flame heaters were causing any problems until Kyle Greenfield at Consulex purchased a pair of pSense hand-held CO2 meters from CO2Meter.com. The meters instantly showed CO2 levels “off the chart”, resulting in improved ventilation for the worksite.
According to Mr. Greenfield, “The readings on these inexpensive meters match very closely with more sophisticated units placed at the site by a CIH monitoring air quality. We use them for spot checks and they are working fine.”
