The testo Bluetooth^® Connector enables efficient, wireless measurement of up to four additional parameters in parallel with your flue gas measurement. Automatic connection to your testo 300 enables you to measure the gas flow and static pressure in parallel using the testo 510i Smart Probe and the flow and return temperature using two testo 115i Smart Probes. Combustion air temperature measurement is also very easy to carry out in parallel using the testo 915i Smart Probe. All parallel measurements are automatically displayed on your testo 300 NEXT LEVEL and can be started and stopped simultaneously. Via the connection to the Smart App, the measurement, documentation and data transfer of all parallel measurements can be carried out effortlessly using the second screen function, the Quick Report function and the e-mail transmission. All measurements stored on your testo 300 NEXT LEVEL can also be conveniently integrated into your in-house software using the QR code (via the previously programmed interface) or simply printed out using the print option on your testo 300 NEXT LEVEL.
