CAS Introduces New Low Cost 3-in-1 Datalogger

New Data Logger Measures CO2, Temperature and Humidity

CHESTERLAND OH - CAS DataLoggers and trusted manufacturer T&D have partnered once more to announce another industry first: the new TR-76Ui CO2 + Temperature + Humidity Logger. This new recorder is a low-cost 3-in-1 logger ideal for monitoring indoor air quality, with a release date in January. The logger is available in two versions: the TR-76Ui which will have T&D's standard temperature and humidity specifications, and the TR-76UiH designed for laboratory work with the wide-range temperature and humidity specifications first offered in the TR-77Ui. Suitable applications include managing CO2 concentration, monitoring temperature and humidity in schools and office buildings, for energy-saving measures such as ventilation and air conditioning controls, in research studies on photosynthesis and growth of plants, and uses in estimating ventilation.

The multipurpose TR-76Ui CO2 Recorder is a three-channel data logger which simultaneously measures and records CO2 concentration, temperature and humidity. This flexible new datalogger has a wide CO2 measurement range of up to 5,000 ppm and a logging capacity of 8,000 data sets (one data set consists of readings for all three channels). These dataloggers also feature a warning monitoring function with contact signal output. Making atmospheric pressure settings for the measurement location ensures more stable and accurate CO2 measurements.

Free software is included which allows users to download data recorded by the device to a PC via USB connection, whereby data from all three channels can be simultaneously viewed in one easy-to-read graph or table. Users can also save data as text for use with common spreadsheet software.

The datalogger comes delivered in an all-in-one package that includes the data logger unit, sensors and the included software. CAS offers two types of packages with different temperature/humidity sensors depending on the required measurement range and accuracy needs. Additionally, by using a T&D Data Collector TR-57DCi (sold separately), it is possible to collect recorded data from the TR-76Ui via infrared communication and immediately check the collected data on the spot, offering umatched convenience.
