The RTR-500/RTR500B series allows you to mix and match an array of wireless radio communication loggers with various Base Units or Data Collectors to meet your needs.
Logged data can be automatically sent via network or mobile communication to be saved in cloud storage or to a specified location.
The RTR-576 is a three-channel data logger designed to measure and record CO2 concentration, temperature and humidity.
External devices such as buzzers and lights can also be connected to the contact output terminal to provide instant on-site notification, signaling when ventilation may be needed.
RTR-576 loggers have a wireless radio communication range with compatible base units of up to 150m (500ft).
Data can be transmitted from a logger to a base unit and then automatically uploaded to cloud storage or saved to a specified location. Data can also be checked on your PC screen or on site with one of our compatible data collectors.
RTR-576 is useful for measuring and managing CO2 in rooms and buildings from both near and far.

*1: Make sure to use the data logger within the operating environment as listed in the specifications.
*2: When continually used in environments with temperatures above 60°C, accuracy of humidity measurements will decrease over time. Also, humidity cannot be measured at temperatures below -20°C.
*3: Stated value is the measurement accuracy of the CO2 sensor when Auto Calibration is operating properly. A change in atmospheric pressure directly influ- ences the reading of CO2, which can cause measurement errors; a decrease in pressure by 10hPa results in a relative decrease in CO2 by 1.6%. In such a case, we recommend carrying out the “Atmospheric Pressure Correction” function found in the software for the Base Unit.
*4: Only “Endless” is available when using the RTR500BW, RTR500BM, RTR-500NW/AW or RTR-500MBS-A as a Base Unit.
*5: For communication with the Data Collector RTR-500DC (Note: Optional serial communication cable TR-6C10 is required.)
*6: In order to use the external alarm terminal, please purchase the optional alarm connection cable (AC0101).
*7: The listed battery life is based on the following usage conditions: Recording at 10 second (or longer) intervals, Current Readings Transmission every 10 minutes, and Recorded Data Transmission once a day. Battery life also varies depending on ambient temperature, radio environment, frequency of com- munication, etc.
The specifications listed above are subject to change without notice.
