Replacement Sensors for TESTO 340 and TESTO 350 Combustion Analyzers

Replacing Your TESTO 340 & 350 Sensors

Maintaining precise and reliable measurements in combustion analysis depends heavily on the condition and calibration of your sensors. Over time, these sensors naturally degrade due to exposure to heat, gases, and environmental conditions. To ensure consistent performance, it’s essential to replace them periodically with the correct, compatible components.

TESTO-340-350-Replacement-Sensors

At Don Wolf & Associates, Inc., we supply replacement sensors for the TESTO 340 and TESTO 350 combustion analyzers—two of the most trusted instruments used for emissions testing, boiler tuning, and industrial combustion monitoring.

TESTO 340 Replacement Sensors

The TESTO 340 is widely used for portable emissions testing and on-site combustion analysis. Common replacement sensors for this model include:

  • Oxygen (O₂) sensors for monitoring combustion efficiency
  • Carbon Monoxide (CO) sensors for detecting incomplete combustion
  • Nitric Oxide (NO) sensors for monitoring nitrogen oxides emissions

Depending on your analyzer’s configuration, additional sensors may be available for other gases such as Sulfur Dioxide (SO₂) or Carbon Dioxide (CO₂).

TESTO 350 Replacement Sensors

The TESTO 350 is a more advanced analyzer used in demanding industrial environments. It supports a broader range of gas sensors, including:

  • O₂ (Oxygen)
  • CO (Carbon Monoxide)
  • NO (Nitric Oxide)
  • NO₂ (Nitrogen Dioxide)
  • SO₂ (Sulfur Dioxide)
  • CO₂ (Carbon Dioxide)
  • HC (Hydrocarbons)

This flexibility allows the TESTO 350 to perform complex emissions monitoring with precision across multiple gas types.

Expert Guidance and Calibration Support

Choosing the right sensor is critical. Using incompatible or expired sensors can lead to inaccurate readings and potentially costly compliance issues. Don Wolf & Associates provides expert guidance to ensure that you select the correct sensor for your specific TESTO model and measurement needs.

Our team can also assist with installation, calibration, and verification to help you maintain the highest accuracy and performance. Every sensor we supply is OEM-quality and designed for reliability in the field.
