High precision technology: what you need for everyday emissions analysis tasks. But that alone is not enough, professional measuring tools must also be flexible, easy to use and able to be used in harsh environmental conditions. Rest assured: our testo 340 exhaust gas meter is the ideal device for you!
testo 340 standard configuration with an O sensor2 and four other sensors (including: CO, COlow , NO, NOlow , NO2 or SO2 for you to choose to order). This allows you to customize your testo 340 to suit your individual needs. The compact design and reliable sensor technology integrated within the testo 340 ensure portability, making it ideal for use in installations or performing inspections of combustion plants or production systems. energy output.
Flue gas analyzer with extended measuring range allows you to perform measurements even at very high gas concentrations (during industrial flue gas analysis). Extended measuring range (auto-dilution) is automatically activated when gas concentrations are suddenly high.
