Product Description

The Testo 320 low cost gas anlayser kit, offering comprehensive combustion system analysis, is designed for the job site and for the contractor who expects more. Use the Testo combustion analyzer for basic testing and tuning of all types of boilers, heaters or furnaces and also to set up and commission more complex multi-stage or modulating heating systems, for accurate combustion efficiency analysis.

Innovative features like the flue gas matrix will graphically display the combustion characteristics, which is an easy way to show if the heating system is running efficiently. Additionally the Testo 320 makes the job easier by displaying from 2 to 8 user-defined parameters simultaneously. The Testo 320 eliminates the guess work and provides accurate combustion system analysis.

You will find the testo 320 basic flue gas analyzer a reliable tool for carrying out installation and maintenance work on heating systems. A compact flue gas analyzer, it can be used to measure flue gas, draught, pressure, ambient CO and differential temperature.

Self-explanatory menu guidance makes operation simpler and makes your job easier. Thanks to the high‑resolution colour display, the readings are easy to read off even when the light is poor. The flue gas analyzer can store up to 20 measurement protocols. It is possible to export the measurement protocols in Excel optionally via mini-USB.

Quality that you can depend on: the testo 320 basic flue gas analyzer is TÜV-tested according to EN 50379, Part 1-3 and to 1st German Federal Immission Control Ordinance (BImSchV)

The Testo 320 flue gas analyzer – facts and features

Flue gas analysis on heating systems: the testo 320 basic flue gas analyzer is equipped with two sensors – an O2 and a CO sensor (without H2 compensation). In the case of CO measurement, the measuring range goes up to 4,000 ppm. You need a flue gas probe for the flue gas measurement (can be ordered separately). A temperature probe is integrated into the probe. All relevant flue gas measurement parameters can therefore be calculated: CO2 value, efficiency and flue gas loss. The flue gas analyzer is also suitable for flue draught measurements or pressure measurements

Changing probes is easy: The probes can be changed by the user. This means you can order other probes specifically required for your flue gas analysis (e.g. multi-hole probe, dual wall clearance probe, flexible flue gas probe)

Single-hose connection: in just one hand movement, all channels for the flue gas measurement can be securely connected via the probe coupling (gas paths, draught, temperature probe integrated in the flue gas probe, which can be ordered separately)

Long service life thanks to the long-life Li-ion rechargeable battery

Built-in magnets enable the flue gas analyzer to be attached to the burner/boiler quickly and easily

Integrated condensate trap: easy to empty

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 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 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 temperatures on radiators

When measuring the temperature on radiators, the flow and return temperatures are recorded in particular and assessed by the tradesman. The flow temperature is defined as the temperature of a 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 in modern, heating technology, spot recording of flow and return temperatures is necessary at certain radiator pipes or screw fittings. 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.
