The TR-76Ui USB Temperature Humidity CO2 Data Logger is a three-channel logger designed to simultaneously measure and record carbon dioxide concentration, temperature and humidity. Making atmospheric pressure settings for the measurement location ensures more stable and accurate Carbon Dioxide measurements. The supplied software enables the user to download data recorded by TR-76Ui to PC via USB connection, whereby data from all three channels can be simultaneously viewed in graph or table form.
The product is an all-in-one package that includes the data logger unit, sensors and software. We offer two types of packages with different temperature/humidity sensors depending on your required measurement range and accuracy needs.
By using a 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.
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.

Simultaneously View Three Measurement Items in one Easy-to-Read Graph
The recorded data downloaded from TR-76Ui units is read in the Multi-Scale Graph where the data of three items, CO2 concentration, temperature and humidity, can be simultaneously viewed in graph or list form, as well as, printed out.
It is also possible from the graph window to calculate and view the highest, lowest and average readings for a desired range (time period).
Large Logging Capacity: 8,000 Data Sets
One data set consists of readings for all three channels: CO2 concentration, temperature, and humidity. There are 15 recording intervals (1 seconds to 60 minutes) to select from. At the longest recording interval of 60 minutes, recording can continue consecutively for one year.
Atmospheric Pressure Correction Function
This function enables the TR-76Ui software to calculate the atmospheric pressure from the altitude at the measurement location. By using a correction factor for the atmospheric pressure at the measurement location, more reliable CO2 concentration measurements can be achieved.
View Current Readings for all Three Channels on LCD
CO2 concentration, temperature, and humidity measurements are shown on the large easy-to-read LCD screen.
While CO2 measurement is always displayed, the display pattern for temperature and humidity can be selected from an alternating display of two or fixed display of either one.
Manage Recorded Data with Common Spreadsheet Software
By using the Multi-Scale Graph, data downloaded from the TR-76Ui can be saved into text format for use with common spreadsheet software.
Transmit Recorded Data to PC via USB Connection
It is possible to connect a TR-76Ui unit directly to your computer with a USB cable. Moreover, it is possible to gather current readings from the TR-76Ui connected to your computer and view those readings in the computer display.
Easy Data Collection on the Spot: No Computer Necessary (TR-57DCi)
By using our Data Collector TR-57DCi (sold separately), it is possible to gather and check recorded data on the spot.
* TR-76Ui support on the TR-57DCi is planned for release at the end of February 2012.
Warning Function with Output Contact
When a set upper or lower limit has been exceeded, it is possible to use the provided output contact on the unit to issue a warning. This function can be used in conjunction with external devices such as a ventilation device.
* To connect to an external device, please use a JST Connector PAP-04V-S.
