The testo 350 Control Unit is used to control emission measurements. It has a clearly structured graphic display and is especially easy to use. There are four different applications in the menu to choose from: burner, gas turbine, motors and user-defined applications. The instructions on the display guide you through the measurement and make the steps leading up to the start of the measurement easier. This saves both time and hassle. The Control Unit can also be used to remote control the Analysis Box when it is not positioned at the exhaust gas pipe or measurement site. This is especially advisable when carrying out work on larger systems.
