The electrochemical sensors in a flue gas analyser wear with use. Original testo sensors restore the instrument’s accuracy, and on modular analysers (testo 340 and 350) you can also extend the measured parameters by adding retrofit sensors.
The table lists the most common references by analyser model. Give us the serial number or model and we will confirm the right sensor.
