Important Note on Orders of the Testo 330i - please note that Testo 330i flue analysers are made-to-order with a lead time once the order is placed.

Once an order is placed, the order cannot be cancelled or returned unless the unit is found to be faulty.

This is the most comprehensive version of the Testo 330i flue gas analyser available. This is the only model in the series which includes H2-compensated CO (carbon monoxide), O2 (oxygen) and NO (nitric oxide) sensors as standard.

Flue gas analysis just got smarter - this is the Testo 330i, a uniquely designed, Bluetooth-enabled, powerful multifunctional analyser designed to make testing easier than ever before.

The Testo 330i does away with the old LCD screen you'll find on many flue analysers completely. Instead, this analyser interfaces directly with your smartphone or tablet running the free app, sending all measurement data wirelessly via Bluetooth! With the app, you can chart all measurement in real-time as digital values or an on a graph, create reports directly from your phone or tablet and even send emails to your colleagues, all while working in the field.

This flue gas analyser also includes an industry-first; a uniquely designed attachment system designed to allow you to use the analyser hands-free! To use, simply install the include Testo FixMount into whatever you're testing, clamp the analyser around the mount using the built-in clamp system and insert your probe. The entire kit will remain fixed in place, with the probe held entirely still by the mount. Once done, use your phone or tablet to configure settings and view your results from a distance!

With the Testo 330i, you'll be able to test absolutely every aspect of a gas system. This powerful flue gas analyser can measure temperature, draught, pressure, oxygen, carbon monoxide, efficiency, flue gas loss, carbon dioxide and (exclusive to set 3) nitric oxide.
