Product Description

Product Description

At the core of the innovative testo 330i flue gas analyzer is the measuring technology of the preceding model testo 330 LL, which has been proven in practice a thousand times over. The outstanding technical features of this flue gas analyzer, such as its user-replaceable long-life sensors, integrated draught and gas zeroing or CO/fresh air dilution have been combined with a revolutionary new method of operation.

The first remote-controlled flue gas analyzer

Operation of the testo 330i flue gas analyzer and the display of readings are implemented wirelessly via the testo 330i App on your smartphone or tablet. Therefore, when making adjustments to the system, you always have the readings to hand. In the App you can also enter customer data, make adjustments to the measuring instrument settings and add comments or photos to measurement protocols on site and send them to the customer or your office via e-mail. If you need the results of your work on paper – no problem: The advanced set also includes a Bluetooth printer with a mains unit.

Requirement: iOS 7.1 / Android 4.3 or newer. Mobile end device with Bluetooth 4.0.

Further advantages of the testo 330i flue gas analyzer

  • User-replaceable long-life sensors with a service life of up to 6 years. This saves at least one sensor replacement over the instrument's typical useful life
  • H2-compensated CO measuring cell. The testo 330i is therefore also approved for the official acceptance testing of heating systems
  • TÜV-tested according to 1st German Federal Immission Control Ordinance (BImSchV) and EN 50379, Parts 1-3
  • Integrated draught and gas zeroing without removing the probe. The probe can remain in the flue during zeroing
  • Fresh air dilution upon exceeding a CO threshold value up to 30,000 ppm

Flue gas analyzer set with practical accessories

The testo 330i flue gas analyzer advanced set includes the following probes:

  • Modular flue gas sampling probe (probe length: 180 mm) with 65 cm long, extra-flexible hose
  • Combustion air temperature probe (probe length: 190 mm)

The patent-pending testoFix probe holder is included in the set, enabling you to quickly and easily attach the probes securely to the flue gas duct. This global innovation also serves as a fall-proof suspension system for the testo 330i flue gas analyzer.
A mains unit for the measuring instrument, the testo 330i Bluetooth/IRDA printer with mains unit and a robust case for the measuring instrument and accessories complete this set.

Differential pressure measurement

You can use the testo 330i flue gas analyzer to check the gas supply on gas boilers. You can therefore measure gas flow pressure and gas resting pressure in order to ensure that the system can be commissioned. You can also use the data specified by the manufacturer for the nozzle pressure to tailor the appliance output to the heat requirement.

Flue gas analysis and flue gas measurement

The testo 330i is equipped with two long-life sensors for measuring O2 and CO and can optionally be upgraded with an NO sensor. Flue gas and draught are measured in parallel, so all relevant flue gas parameters are displayed simultaneously on the smartphone.

O2 supply air measurement

In balanced flue systems, you can use the testo 330i flue gas analyzer to check whether there is a leak in the flue gas system. Measure the O2 content of the combustion air in the dual wall clearance to ensure that no flue gas is getting into the combustion air supply, thus preventing damage due to condensate or impairment of the combustion process.
