Announcing our New Wireless Data Logger RTR-576/576-H for CO2, Temperature and Humidity

Date Issued: October 09, 2012

T&D Corporation is proudly releasing a new lineup of Remote Units for the RTR-500 Series: Wireless Data Logger RTR-576 and RTR-576-H.
This versatile data logger can be used in a wide range of applications from personal to business use; for measurements of home environment, CO2 measurements in offices and other buildings, and/or energy-saving measures such as ventilation and air conditioning controls. By using our RTR-500 Series Base Unit, the recorded data in the RTR-576/576-H not only can be collected via wireless communication, but can also be used for data monitoring, warning monitoring, and data management through networks to construct a data logging system to match your needs and environment.

* RTR-576-H is equipped with the HHA-3151 Temperature and Humidity Sensor with extended range and higher precision of measurements of temperature and humidity.


Measurement Range CO2 : 0 to 9,999 ppm
Temperature:0 to 55°C
Humidity : 10 to 95%RH
CO2 : 0 to 9,999 ppm
Temperature:-30 to 80°C
Humidity : 0 to 99%RH
Accuracy(CO2) ±(50 ppm + 5% of reading)*1[at 5,000 ppm or less]

±5%RH [at 25°C, 50%RH]
±0.3°C [at 0 to 50 °C]
±2.5 %RH (at 25 °C, 10 to 85%RH)
Logging Capacity 8,000 data sets (One data set consists of readings for all three channels: CO2 concentration, temperature, and humidity.)
Wireless Transmission Range About 150 meters (500 ft) if direct and unobstructed
Power AC Adaptor (AD-0638 or AD-0638-C), AA Alkaline Battery x 4 (for backup)
Operating Environment Temperature: 0 to 45 °C, Humidity: 90%RH or less (no condensation)

*1: 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 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 supplied with the Base Unit.
