pSense saves money for Shedd Aquarium

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...

NASA compiles list of best plants to clean indoor air

NASA research scientists have announced that the common indoor plant may provide a natural way of helping combat sick building syndrome. Based on the use of common indoor plants for indoor air purification, NASA studied about a dozen popular varieties of ornamental plants to determine their effectiveness in removing several key pollutants associated with indoor air pollution. NASA research found that living plants are so efficient at absorbing contaminants in the air that some will be launched into space as part of the biological life support system aboard future orbiting space stations. English ivy, philodendrons, spider plant and the golden...

CO2 Meters Improve Indoor Gardening

Indoor growers have long known the benefits of increasing carbon dioxide levels in greenhouses. Carbon dioxide, light, and water are all necessary for photosynthesis, the chemical reaction that creates plant growth. Studies have shown that even when optimum levels of light, water and nutrients are available, plant growth will still be limited by the amount of carbon dioxide available during the daylight growth cycle. While different varieties of plants respond to different maximum CO2 levels, in general, doubling CO2 from outdoor air levels to 800 ppm results in an average of one-third greater improvement in plant growth and productivity. This...

Can the TIM10 work for LEED certification?

We receive several calls a week asking if the TIM10 indoor air quality meter can serve as a low-cost alternative to wall-mounted CO2 sensors controlling variable air-flow devices for LEED certification, as defined by the U.S. Green Building Council. The LEED specification treats CO2 as the “canary in the mineshaft” for air quality. Studies repeatedly show that an increase in CO2 levels in a room directly corresponds to an increase in dust, chemicals, mold, germs, and many of the other airborne contaminants that lower our quality of life. The LEED 2.2 EQ-Credit 1 Requirements are clear: they encourage a permanent...

Portable Power for TIM10 and TIM12

We’ve used this 12VDC auto adapter set to 5VDC and a portable 12VDC NiCad car starter to run both the TIM10 Desktop CO2, Temperature & Humidity Monitor and the TIM12 Air Quality Monitor with data logging. With this configuration, it is easy to take the TIM10 or TIM12 outdoors to measure CO2 for classroom projects, for example. This adapter (unlike less-expensive ones) is rated at 1000mA…most others are not. No wiring required – the adapter comes with different plugs – just remember that the center pin is positive. Also works great in cars or anywhere you have access to a...
