The United States is consuming energy considerably more efficiently and with lower emissions than just five years ago thanks to a number of modern technologies that are changing decades-old patterns, according to a report from Bloomberg New Energy Finance and the Business Council for Sustainable Energy.
The data logger TR-76Ui-H is a three-channel recorder designed to simultaneously measure and record CO2 concentration, temperature, and humidity. The model achieves a temperature measurement accuracy of ±0.3°C between 10° and 40°. The accuracy is ±0.5°C at all other temperatures.
One measure of the impact of CO2 as a refrigerant comes with the increasing number of applications in North America, where its use can be stymied with questions related to codes and regulations in municipalities as well as the learning curve of installation and service technicians.
