testo 340

testo 340 flue gas analyzer, incl. rechargeable battery, calibration protocol and carrying strap, equipped with O2 sensor, integrated flow/differential pressure measurement

  • measurement range extension for Single dilution slot or optional for all sensors
  • pressure-/ flow-measurement standard in every testo 340
  • automatic flow-controlled gas pump
  • 18 standard fuels and additional 10 user-defined fuels – Fuel data is calculated using software easyEmission

Rising fuel costs for thermal systems highlight more and more the need for efficiency monitoring using emission measurements. A practical, easy-to-use emission analyzer for a variety of applications is therefore ideal.

  • The unique measuring range extension feature facilitates unlimited measurements even at high gas concentrations.
  • testo 340 is equipped with an O2 sensor as standard. 3 additional gas sensors can be individually configured at any time so your analyzer is optimally adapted to your measurement job.
  • Compact design combined with reliable engineering makes testo 340 the ideal analyzer for commissioning, service and maintenance work as well as measurements for monitoring purposes.
  • - Industrial burners

  • - Stationary industrial engines
  • - Gas turbines
  • - Thermal processes
  • TÜV approval / EN standard
  • - Accuracy approved for O2, CO2, CO, NO, NOlow, °C, hPa to EN 50379 standard, Part 2
  • - Approved sensor change (adjustment without test gas)
  • automatic flow-controlled gas pump
  • modular gas sampling probes
  • internal data logging
  • option: Data transfer and real-time-analyzer-control via Bluetooth® module and software easyEmission
  • 18 fuels stored in the instrument as standard, more are user-specifically configurable with easyEmission

testo 340 must be equipped with a second gas sensor otherwise the analyzer cannot function. Max. 3 additional sensors can be fitted.
