Profit from the strength of the world market leader in heating measurement technology.

Testo and flue gas measurement technology – a success story for over three decades. We already recognized the key role played by electronic flue gas analysis for more energy efficiency in 1978, and introduced the first flue gas analyzer to the market.
At Testo , you will find a broad spectrum of sophisticated flue gas analyzers.

Broad spectrum of products

Quality, innovation, experience – these virtues make us the number one in the world in heating measurement technology. Benefit from this now, by purchasing our new flue gas analyzers testo 310 and testo 320, as well as the proven testo 330 LL.
From the robust allrounder for basic measurements, to the efficient multi-talent for graphic flue gas analysis and the powerful high-end instrument with revolutionary longlife sensors, the product range covers the entire spectrum of flue gas measurement on heating systems.

testo 310. Flue gas analysis the easy way.

The new testo 310 combines simple functions with a high level of measurement accuracy, and is thus perfect for all basic measurements on heating systems.

Long battery lifetimes of up to 10 hours guarantee you high availability. Its easy handling and compact design make it a robust tool for daily work – even when things get rough. The printer specially developed for the testo 310, including infrared interface, allows you to easily create clear reports on site.

Product properties in detail

Applications

Technical data

	Robust Robust and light instrument for daily use - excellently suitable even for rough and dirty surroundings.
	Illuminated display Two-line display and clear menu structure. Easy to operate and clearly legible.
	Automatic zeroing of sensor Automatic zeroing of the gas sensor in only 30 seconds after starting, which can be cancelled if not required.
	Lithium rechargeable battery Operation with lithium rechargeable battery (1500 mAh) – no need to change battery, up to ten hours running time, charging via USB possible.
	Probe filter Quickly and easily exchangeable
	Attachment Integrated magnets for easy fixing to burner.
	Condensate trap Integrated condensate trap – very quickly and easily emptied.
	Printer Documentation via infrared interface.

	Flue gas measurement In this central measurement in the course of flue gas analysis, you directly determine CO and O ₂ content as well as the ambient and flue gas temperatures. From these values, the testo 310 calculates all further measurement parameters such as CO ₂ concentration, degree of effectivity and flue gas loss.
	Ambient CO measurement With this safety measurement, you determine whether flue gas spillage is spreading in the vicinity of the heating system. This can cause high CO concentrations in heating and living rooms. Because these are life-threatening, this meaurement should alsways be carried out first.
	Draught measurement Draught measurement ensures that the flue gas from a heating system is correctly drawn off through the flue. With this measurement, you determine whether the system has the correct negative pressure. At the same time, the flue gas temperature is measured.
	Differential pressure measurement The differential pressure measurement tests the gas supply to gas boilers. To do this, you measure the difference between the pressure in the gas line and the ambient pressure. The measurement is important for the adjustment of the jet pressure.

Exchange of probes in a few seconds.

The flexible and efficient probe concept supports your top service.

Wide selection allows adaptation to any applications
Fast link with bayonet connection
All gas paths in one probe
Different lengths and diameters
Fine pressure probe to measure draught and gas parallel to flue gas

The Testo probe range allows many more measurements on a heating system. Thanks to the probe coupling of the testo 320 and testo 330 LL, exchanging is especially efficient. All probes are connected via a fast connection. All gas paths are connected to the instrument at once with the bayonet connection. You can change the particle filter which protects the gas paths from dirt just as quickly. Whether a multiple-hole probe, a dual wall clearance probe or a flexible flue gas probe – the wide selection allows adaptation to any application.

Different lengths and diameters, which also occur in a standard flue gas pipe, mean you are never left at a heating system without the right measurement solution.
