Call For Price

The RFCO2RHTemp2000A is a wireless data logger that measures and records carbon dioxide, humidity, and temperature levels in a variety of applications. This data logger is ideal for use in air quality studies including HVAC applications and much more. The RFCO2RHTemp2000A data logger comes with a 16 ft cable connected to the CO2 sensor, making it ideal for placement within enclosed environments such as an incubator to ensure optimum levels. The logger features an LCD screen which provides instant access to current readings, as well as minimum, maximum, and average statistics. The device also features configurable alarms, battery life indicator, and the ability to reset statistics without impacting the data collection. The logger features a convenient wall mount, while the CO2 sensor is equipped with dual lock for easy and secure placement and effortless mobility. Temperature recorded on the RFCO2RHTemp2000A can be expressed in °C, °F, °R, or K while humidity can be shown in %RH, mg/ml, and Dew Point. Carbon dioxide can be expressed as either ppm or as a percentage. All units can be viewed on both the LCD screen as well as in the software. The device can be used to determine ventilation efficiency in a variety of environments including buildings, offices, hospitals, schools, and laboratories. By determining the levels of carbon dioxide, improvements can be made to the ventilation systems and energy saving opportunities become more easily identified. The RFCO2RHTemp2000A can be used as a standalone data logger, or may used wirelessly to transmit collected data back to a central PC for real time monitoring. The RFCO2RHTemp2000A can be used as a single wireless data logging system, or can be expanded to a large scale system including hundreds of data loggers. The RFCO2RHTemp2000A utilizes the latest version of the MadgeTech 4 Data Logger Software to analyze data or generate reports in graphs or tabular formats. Summary and statistic views are also available for further analysis, as well as the capability to export to Excel.
