Description

The RTR-576 is a three channel data logger designed to measure and record CO2 Concentrations, temperature and humidity. A contact output terminal is also available to connect external buzzers or lights to provide local on-site alarms or notification. The RTR-576 can be used to monitor and manage CO2 conditions in classrooms and greenhouses.

*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 influences the reading of CO2, which can cause measurement errors; a decrease in pressure by 10 hPa 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: There are US models and EU models in the RTR500B Series. They cannot be used together because they have different wireless specifications.
*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 communication, etc.
*8: Also compatible with the following discontinued products: RTR-500DC, RTR-500, RTR-500NW/AW and RTR-500MBS-A.
