4-year warranty on the flue gas analyzer
Bigger savings with longlife (LL) sensors. Because the O2 and CO sensors need to be replaced less often (typically once every six years and therefore once less) you save on costs.
Wide range of optional sensors (i.e. NO, COlow, NOlow sensors) that allow you to customize your analysis tool to suit your individual requirements and saves you from having to buy other flue gas meters or analysis tools
Sensor connector for quick `n easy sensor change. All gas circuits can be connected to the analysis tool via a bayonet lock
The testo 330-2 LL pro flue gas analyzer – one tool for a host of measurements
The testo 330-2 LL pro flued gas analyzer is designed to allow you to carry out all standard installation, service and maintenance measurements in and around heating systems with only one device.

Application
Ambient CO measurement in the heated environment
Carbon monoxide (CO) is a colourless, odourless and taste-free gas, but also poisonous. It is produced during the incomplete combustion of substances containing carbon (oil, gas, and solid fuels, etc.). If CO manages to get into the bloodstream through the lungs, it combines with haemoglobin thus preventing oxygen from being transported in the blood; this in turn will result in death through suffocation. This is why it is necessary to regularly check CO emissions at the combustion points of heating systems and the surroundings. Measuring pressure on burners (nozzle pressure, gas flow pressure, etc.)
Standard readings taken during services of domestic heating systems include checking the gas pressure on the burners. This involves measuring the gas flow pressure and gas resting pressure. The flow pressure, also called supplied pressure, refers to the gas pressure of the flowing gas and resting pressure of the static gas. If the flow pressure for gas boilers is slightly outside the 18 to 25 mbar range, adjustments must not be made and the boiler must not be put into operation. If put into operation nonetheless, the burner will not be able to function properly, and explosions will occur when setting the flame and ultimately malfunctions; the burner will therefore fail and the heating system will shut down.
Measuring the flue gas parameters of the burner (CO, O2, and temperature, etc.)
The flue gas measurement for a heating system helps to establish the pollutants released with the flue gas (e.g. carbon monoxide CO or carbon dioxide CO2) and the heating energy lost with the warm flue gas. In some countries, flue gas measurement is a legal requirement. It primarily has two objectives:
Ensuring the atmosphere is contaminated as little as possible by pollutants; and
energy is used as efficiently as possible.
Stipulated pollutant quantities per flue gas volume and energy losses must never be exceeded.
Measurement in terms of results required by law takes place during standard operation (every performance primarily using the appliance). Using a Lambda probe (single hole or multi-hole probe), the measurement is taken at the centre of flow in the connecting pipe (in the centre of the pipe cross-section, not at the edge) between the boiler and chimney/flue. The measured values are recorded by the flue gas analyzer and can be logged either for print out or transfer to a PC at a later stage.
Measurement is taken by the installer at commissioning, and if necessary four weeks later by the flue gas inspector/chimney sweep, and then at regular intervals by the authorised service engineer.
Measuring temperatures on radiators
When measuring temperatures on radiators, the flow and return temperature are recorded in particular and assessed by the tradesman. The flow temperature is defined as the temperature of the thermal transfer medium (e.g. water) that the system is supplied with. The temperature of the medium flowing out of the system is accordingly called the return temperature. To prevent losses within the heat distribution system and achieve a better level of efficiency spot recording of flow and return temperatures are necessary. Implementation of relevant measures ultimately leads to hydraulic adjustment on the basis of knowledge about the flow and return temperatures. This defines a procedure with which every radiator or heating circuit of a flat radiator within a heating system is supplied at a set flow temperature with the precise amount of heat needed to achieve the ambient temperature required for the individual rooms. Flawed operating conditions will result in considerable excess consumption of electricity and heating energy. The German Energy Saving Regulation (EnEV) therefore requires hydraulic adjustment for systems being set up or overhauled for this very reason.
