testo 340 4-Gas Industrial Combustion Analyzer

testo 340
The ultimate instrument in
portable combustion tuning

Optimizing combustion, increasing efficiency and
minimizing fuel use are necessary to compete in today's
market. The testo 340 provides the information to
understand your process, enabling you to make informed
combustion decisions. It is the ideal tool to confirm proper
set-up or identify emission problems.

Automatic – flow controlled sampling pump
Sample flow rate is controlled for constant reading and to
pull from longer sample lines

Infrared printing
Print records (flash Mode) to testo infrared printer (10 year
thermal paper)

Calibration records with sensor output/life graph
Display & print calibration record

Integrated pressure sensor
• Measure draft or differential pressure
• Simultaneously measure exhaust gas and flow velocity
  for flow

18 fuels to choose from, plus
10 – user defined fuels (input from easyEmissions)

Rugged and durable – 4-Gas Flexibility in a rugged,
compact handheld design
• Multi sensor capability & equipped to handle
  extreme concentrations
• Automatic Sensor Protections keeps your
  analyzer working longer
• Designed for simple, fast operation and constructed
  for demanding daily rugged use!

Onboard Diagnostics
– The information button gives you power to know.
Simply go to the diagnostics screen to see instrument status
• Perform an automated quick leak check before your test.
• See the rechargeable lithium battery status (lasts approximately 6 hours with pump on)
• Review the pump flow rate (liters/min)
• Display error status with description and diagnosis and last service/maintenance date
• Graphic representation of sensor calibration data
• Shows status of condensate trap

easyEmissions - A powerful and efficient software tool
easyEmission software gives you extraordinary data management skills with real time
analyzer control. It has the power to import/export data from a variety of formats and
prepare custom reports and documents using today's common Windows® based applications
• Intuitive user interface
• Easily customized display screens
• Results in tabular forms, charts and graphs or pictures
• Logging intervals 1/sec to 1/hr

Rugged Gas Sampling Probes for all Types of Applications
Every probe and hose assembly is constructed of the highest quality material.
The probes cam-lock connection to the 340 assures your security and safety during
testing. The standard Teflon hoses are also heat-resistant.
• 12 inches to 28 inch length probes
• Withstand temperatures up to 1800°F
• Hoses can extend to 25 feet with extensions (optional)
• Probe lengths to 9 feet and temperatures to 3200°F (optional) for extreme
tuning applications

NEW – Replaceable Interference Filters
Some combustion sources run normally high concentrations while others are high because of inadequate control or flawed set-up. High concentrations can reduce the normal life span of sensors. Testo's solution is replaceable interference filters on the CO and NO sensors. Analyzer diagnostics will display the filter lifetime in ppm hours to inform you of filter change-out which is easy and quick to replace. This simple process increases accuracy and extends sensor lifetime.
