testo 340 Diesel Kit
The Testo 340 is a portable emission analyzer designed for diesel exhaust and industrial combustion testing. Configured with O₂, CO, NO, NO₂, and CO₂* it enables precise NOx measurement while remaining compact and robust enough for demanding field environments. With smart features like an automatic dilution system and powerful data logging, the Testo 340 is trusted across mining, power generation, and industrial sites.
List of Benefits
- Accurate five-gas capability: O₂, CO, NO, NO₂, and CO₂*
- Automatic dilution for high gas concentrations (up to 5×)
- Rugged, field-ready design with strong magnets and protective housing
- Easy data management with Testo easyEmission software
- Optional infrared printer and Bluetooth connectivity
- Portable kit with everything needed for on-site testing
The Testo 340 combines accuracy, flexibility, and durability in one portable unit. The base configuration comes with an O₂ sensor and space for three additional sensors, allowing customised measurement setups. With O₂, CO, NO, NO₂, and calculated CO₂*, the analyzer provides precise NOx and combustion values essential for diesel exhaust testing and compliance. The built-in dilution system automatically adapts to high gas concentrations, protecting sensors and extending service life. Paired with Testo’s easyEmission software, the 340 simplifies diagnostics, reporting, and long-term monitoring. Its rugged housing, strong probe, and integrated magnets ensure it performs reliably in harsh industrial conditions. *Calculated from O₂
