Optimizing the combustion process and increasing fuel efficiency are necessary to compete in today’s market. The testo 340 can be configured to be the ideal combustion analyzer for Boiler and Burner testing.  The testo 340 Boiler and Burner Kit comes with the following items:
  • testo 340 unit with O2, CO and NO sensors
  • 12” stainless steel probe (temp max of 932 F) and 7-foot Teflon lined hose.  
  • Transport case
  • Power Supply
  • Extra particle filters
  • Printer IR
  • Printer paper


Built to last

  • Long life-time CO and NOx sensors (up to 5 years) make cost of ownership the best in market.  Field exchangeable sensors allow greater flexibility.
  • The automatic dilution (range extender) factor-5x increases the CO range to 50,000 ppm.  The analyzer will calculate and display the corrected values.  User defined setpoints means you can extend the CO sensor life and maintain accurate measurements.
  • Rubberized shock resistant housing and clear over-plate protects analyzer and display screen. Magnets on back housing allows you to mount the analyzer for easier viewing.


Beneficial features and useful options

  • The back-lit display is easily customized, can display from 4 to 8 lines, or show a variety of measurement options, such as PPM values or as MMBtu/hr.
  • Important calculation including, combustion efficiency, excess air calculations, corrected NOx and corrected CO values. 
  • 18 fuels to choose from
  • No need to remove the probe from the stack - simply press the "fresh air purge." It increases sensor life and keeps you off ladders and safely on the ground
  • Onboard Diagnostics – Push the i (information) button and scroll down for instrument status.
  • Draft and differential pressure and Mass Emission calculations (i.e. lbs./hr., tons/yr) with any Pitot tube
  • Options:
    • Add the NO2 sensor for a better NOx measurement that will include NO and NO2
    • Swap the standard NO sensor for the Low NOx or Low CO options with 0.1 ppm resolution
    • Hose extensions -9-foot quick connect extensions with integrated thermocouple means you can extend the hose to 25 feet.  Simply disconnect them for easier, less bulky transport.
    • Industrial sample probes from 3 feet to 9 feet long and from 1112 °F to 3200 °F
    • External Gas conditioning system for wet sources
    • easyEmission software - for real time data logging or downloading from instrument memory.


Velocity - Mass Flow - Lbs. / Hr, Tons / Year

With an optional pitot-tube you can also measure the velocity of the flue gas and evaluate the duct and back pass efficiency.  By inserting the sampling probe in the flue, the testo 340 will simultaneously calculate mass flow of NOx and CO in lbs/hr or tons/year.  Truly your go to instrument for combustion analysis


testo 340 – Probes and hoses for every application.

The probes are specifically designed for boiler testing. A modular design incorporates integrated thermocouples.  Simply "click-on" longer probes or ones that can withstand temperatures up to 1832 °F. Teflon-lined sample hoses resist kinking, are resistant to flue gas acids and provide the highest level of accuracy. Heavy particulate loading from coal or bio mass boilers are easily handled with the sintered filter options.  And if these are not enough, testo has a full line if industrial probes and hoses to cover everything else.  Click on the PROBE tab above to see the many sampling options.
