CO2 Finds, Kills Bedbugs
With the drastic increase in bedbug infestation over the last several years, scientists and researchers have searched for safe, cost-effective methods of eliminating these pests.
Because bedbugs are attracted by the elevated carbon dioxide levels in human respiration, CO2 can be used to determine if a bedbug infestation exists. And because high levels of CO2 kills bedbugs, pest control companies are using CO2 instead of toxic insecticides to fumigate hotel rooms and even entire buildings.

CO2 Levels: What you need to know. Carbon dioxide - CO2 - is in every breath you take. Although it is normally non-toxic, high CO2 levels are hazardous. For example, workers have suffocated from CO2 in enclosed spaces like beverage bottling plants. However, even at low levels CO2 can impact our bodies. That is one of the reasons why schools and office buildings monitor CO2 levels. So what's the difference between "good and "bad" levels? Here's a quick list:
• 350-400ppm Normal CO2 level that occurs naturally in the atmosphere
• 600-1,000ppm Typical CO2 levels in a well-ventilated home, classroom or office building
• 800ppm Recommended for maximum plant growth
• 1,000ppm ASHRAE maximum level for occupied buildings
• 2,000ppm Level at which some people begin to feel drowsy
• 3,000ppm Typical level in an enclosed car with windows rolled up after half an hour
• 5,000ppm OSHA maximum average over an 8-hour work day
• 10,000ppm (1%) High limit CO2 levels on a submarine
• 15,000ppm (1.5%) Shortness of breath and increased heart rate
• 30,000ppm (3%) Muscular pain, headaches
• 40,000ppm (4%) CO2 in an exhale from a human • 100,000ppm (10%) loss of consciousness in 5-10 min
• 300,000ppm (30%) death by CO2 poisoning

Sampling Data Loggers Make Finding CO2 Easy
In response to your requests, our engineers have developed a line of CO2 meters that can sample CO2 levels remotely. For applications that require long-term remote data logging of CO2 levels in an enclosed environment, the 1% and 30% Sampling Data Loggers are perfect. These units include inlet and outlet ports so you can test a gas sample and return it in a closed system. Field technicians, scientists and students who need real-time remote CO2 sampling use our 1% and 30% Sample Draw CO2 Meters. These hand-held, battery operated units allow you to test CO2 levels in remote places - perfect for testing for CO2 leaks in a pipe joint, for example. All our sampling meters use our new DAS Software, and include a built-in high-efficiency micro pump, data transfer/logging cable, 4AA battery power, wall adapter, in-line moisture trap, tubing and 3 different hose barb sizes for custom applications. |

2 New High-CO2 Probes
Probe makes logging up to 100% CO2 easy. Our 1% CO2 Probe has been popular with students and scientists for quite a while, but we continued to get requests for a Probe that could test higher CO2 levels. Therefore, our team has designed the new K-33 30% CO2 Probe and C20 100% CO2 Probe. Like the original probe, these units are designed for years of rough, real-world use. They include a CO2 sensor encased in a tough ABS plastic shell with a heavy-duty USB cable permanently attached using a strain-relief fitting. All our probes use a standard USB connector to attache to a MS-Windows PC running our DAS software for real-time CO2 measurement or for long term data logging. Using active USB extension cables, you can test CO2 levels up to 64ft (20m) away from your PC. |

Calibration Gases Now Available at CO2Meter.com
By default, our CO2 sensors use ABC - Automatic Baseline Calibration. For sensors that read normal (400ppm) CO2 levels at least once a day (in an office or classroom, for example) ABC has proven to be a cost-effective and long-term alternative to yearly calibration of sensors using a calibration gas. However, in some situations ABC cannot be used. For example, some installations require the CO2 sensor to be exposed to consistently high CO2 levels for long periods of time. In these cases, you should use a calibration gas. If you need calibration gas or have more questions, contact Rob Walden at 877-678-4259 or sales@co2meter.com and he can help you choose which calibration method is best for your application. |
