Some products are “green” because they help us monitor the indoor environment. These include carbon monoxide (CO) detectors, lead-paint test kits, and other IAQ test kits or devices. Because some products, such as CO detectors, are so common, we look for evidence of superb performance or other features in order to consider them exceptional enough for listing in GreenSpec.

    CO2Meters offers a wide range of carbon dioxide sensors and data loggers that can be used to improve indoor air quality and save energy. These units use “non-dispersive infrared” (NDIR) technology and are available in portable units as well as wall mounted. The company’s eSense and aSense units—used in demand-response ventilation—come with fresh air indicators that are triggered when preset CO2 levels are reached. The company also offers monitors and sensors for for temperature, humidity, carbon monoxide, methane, and VOCs.

    KMC Controls’ carbon dioxide sensors monitor CO2 levels in commercial, healthcare, and other applications and communicate that information to demand control ventilation systems. These self-calibrating units improve indoor air quality by providing ventilation where needed and reduce energy waste caused by over-ventilation of unoccupied spaces. They are RoHS compliant with low levels of lead, mercury, cadmium, and other toxicants. The company also offers smoke detectors and sensors for temperature, humidity, pressure flow, and occupancy.

  • CRL Series CO2 Based Occupancy Sensor
    Veris Industries
    The CRL Series remote mount carbon dioxide sensor from Veris Industries monitors CO2 levels in commercial settings and adjusts the mechanical system accordingly to help improve indoor air quality and occupant comfort. The CRL uses an inexpensive, solid-electrolyte CO2 sensing technology that comes factory calibrated, lowering installation labor costs and minimizing troubleshooting. Accurate down to about 30 parts per million (ppm) CO2, these units have a detection range between 2000 and 5000 ppm and trigger ventilation or an alarm, based on ventilation setpoints. An LED display indicates whether the system is working normally, venting, or malfunctioning.

    Aircuity, Inc.
    OptiNet™ is a permanent, automated, building-integrated system for continuously sampling and analyzing indoor air for contaminants. The OptiNet system relies on a network of MicroDuct™ structured cable that collects air samples from throughout the building for analysis using the centralized SST600 Sensor Suite instrumentation. Measurable environmental parameters include temperature, relative humidity, carbon dioxide, particulates, total volatile organic compounds (TVOCs), and carbon monoxide. Sophisticated controls can interface with a building management system and Aircuity’s Internet-based Knowledge Center™ for viewing facility data and providing performance evaluation reports. The MicroDuct structured cable is made of carbon nanotubes with a Kynar® fluoropolymer sheathing.

    Detec Systems, LLC
    Detec Systems offers a real-time, automated moisture intrusion monitoring system for building envelopes and roof systems. The detection system uses a proprietary moisture-detection tape with copper conductors and stainless steel probes which can be installed in nearly 100% of the building envelope. Zones of tape are connected to onsite sensor modules that communicate with Detec’s central monitoring center. The Detec system is primarily used in commercial, institutional and multi-family/residential buildings. The system can monitor any type of building structure, including wood-frame, non-combustible steel construction, window wall, curtain wall and concrete. The technology was originally developed for the telecom industry, and has been used to monitor cable routes for moisture intrusion since the early 1980s.

  • Low Level CO
    CO-Experts, Div. of G. E. Kerr Companies, Inc.
    The Low Level (LL) CO Monitor displays carbon monoxide (CO) levels as low as 10 ppm, audible and visual warnings at 10, 25, 35, 50, & 70 ppm with immediate, automatic hush & hush overrides at all levels. Unlike most CO detectors, these monitors (in addition to sensing higher levels) are designed to alert occupants to low levels of CO that may be harmful, but not necessarily fatal, so that corrective measures may be taken. Most CO detectors sound an alarm only after much higher levels are sustained for a protracted period of time. The CO-Experts Low Level Monitors take a CO reading every second, then averages 5 readings, updating the display and audible alarm every 5 seconds. The monitor provides 1 ppm resolution. The reasons for diagnostic failure warnings are shown on the display as well as CO exposure data storage timelines, peak, time of peak, duration of CO exposure, and the resulting COHB in the blood stream. If not cleared by owner, the stored data will be retained for 2 years & 8 months. The sensor is fully monitored and provides end of life warning. The unit comes with a 1-year warranty and a 5 year expected lifetime. An annual calibration and warranty renewal service is available for an additional charge.

    Atwood Mobile Products' CO alarm is certified by the Canadian Standards Association, which includes specifications for both alarm longevity and time-of-manufacture testing. Atwood uses a patented electrochemical technology to alert building occupants to the presence of carbon monoxide. According to the company, the sensor is more accurate, more energy efficient, and less sensitive to humidity than competing models. A digital display updates CO levels every 30 seconds and indicates battery and sensor conditions. The unit requires 3 AA batteries. A picture-frame leg allows installation in various locations. The Canadian Standards Association certifies Atwood CO alarms for use in RVs.

    Each EPA-recognized Pro-Lab test kit comes with a pair of radon detectors. The detectors use liquid scintillation technology with silica-gel desiccants, so they require only 96 hours of exposure before they are sealed and sent back to the lab for analysis. Results will be returned within one week; express 2-day analysis is also available. Pro-Lab also offers kits to detect pesticides, molds, carbon monoxide, asbestos, and bacteria in water, paints, dust, and on surfaces.
