testo 320 set in detail

testo 320 flue gas analyzer, TÜV-tested according to EN 50379, Parts 1 - 3:
  • Flue gas analysis on heating systems: the testo 320 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
  • Self-explanatory menu guidance makes operation simpler and your job easier. Thanks to the high-resolution colour display, the readings are easy to read out even in poor light conditions. The flue gas analyzer can store up to 500 measurement protocols. The free Excel tool enables you to export your measurement protocols to Excel via mini-USB
  • When you purchase the flue gas analyzer, you get a 2-year warranty (for the instrument, probe and O2/CO sensor)
  • Changing probes is easy: the probes can be changed by the user. This means you have the option to 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: just one hand movement is needed to securely connect all channels for flue gas measurement via the probe coupling (gas paths, draught, temperature probe integrated in the flue gas probe)
  • 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
  • Integrated condensate trap – easy to empty
Compact basic flue gas probe:
  • On the basic flue gas probe with 180 mm long probe shaft, the flue gas path and temperature channel can easily be connected to the measuring instrument via a practical bayonet lock
  • The compact basic flue gas probe is equipped with a dirt filter which protects the measuring instrument and its sensors
  • The thermocouple NiCr-Ni, which is integrated in the probe shaft, enables temperature measurement up to 500°C
Pressure connection set:
  • The pressure connection set enables the measuring instrument to be used to measure gas or air pressure. To do this, the hoses are attached to the test nipple of the measuring point and connected to the flue gas analyzer via the measuring instrument adapter
IrDa infrared printer:
  • The infrared printer preserves your readings in black and white. It enables immediate printout of readings, including date and time

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:

  1. Ensuring the atmosphere is contaminated as little as possible by pollutants; and
  2. 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.

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 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.
