THE SIMULTANEOUS measurement and recording of three environmental factors – CO2 concentration, temperature, and humidity – can be performed automatically on the new TR-76Ui-H data logger from TandD.
This three-channel recorder offers temperature measurement accuracy of +/-0.3C from 10C to 40C, and +/-0.5C across its full range from -30C to +80C.
The unit has a CO2 range up to 9999ppm, accurate to +/-50ppm +5 percent of reading.
Humidity measurements is from 0-99 percent with accuracy of +/-2.5RH at 25C.
The TR-76Ui-H can to store up to 8000 data sets and can download recorded data to a PC via USB connection, enabling data from all three channels to be simultaneously viewed in graph or table form.
By using a handheld Data Collector TR-57DCi (available separately) with graphical display, it is possible to collect recorded data from the TR-76Ui-H via infrared communication, allowing immediate on the spot assessment.
