A new recorder system incorporates the TelAire® 7001 carbon dioxide (CO2) and temperature monitor and a choice of data loggers with software that provides real-time viewing when performing indoor air quality (IAQ) studies and balancing HVAC systems. The recorder system extends the usefulness of the monitor in performing IAQ studies by adding highly accurate and flexible data recording. Featuring the QuadVolt four-channel data logger, this system offers real-time viewing of measurements on a PC or laptop, and has software that permits customizable engineering units, overlaid graphs, and export to MS Excel®. Providing ±0.10 percent FSR accuracy and 32,767 measurements per channel (CO2 and temperature), the system allows for the use of two additional monitors for multiple rooms or lobby and outside referencing.
