testo 300 flue gas analyzer with Smart-Touch operation – Features

Impressive measuring technology and quality

  • O2, H2-compensated CO sensor up to 8,000 ppm and NO sensor
  • Longer sensor service life thanks to automatic sensor protection
  • TÜV-tested according to first German Federal Immission Control Ordinance (BImSchV) and EN 50379, Parts 1-3
  • Integrated fine pressure
  • Versatile probes and fast probe changes: take advantage of quick-change probes and the multi-functional handle for attaching a variety of probe shafts (each available to order separately). You can for instance use longer probe shafts for flue gas pipes with larger diameters or flexible probes for difficult-to-access measuring points
  • Optionally available probes and accessories for further measuring tasks, such as gas flow pressure measurement, gas pipe testing, differential temperature measurement and ambient CO measurement

Smart, intuitive, efficient: easy operation in day-to-day work

  • Smart-touch display for intuitive operation of the flue gas analyzer: the display responds without delay – just as easy as on your smartphone
  • Get the measurement result faster: clearly structured measurement menus for all relevant measurements
  • Create documentation (including measuring value, measuring location and customer data) easily on site
  • Save PDF measurement reports directly in the instrument and always have them available
  • Signature function: your customer can sign measurement reports directly on the instrument
  • E-mail measurement reports directly to the office or to customers via WLAN (hotspot)
  • Large 5-inch HD display – enables you to see all the system's parameters immediately
  • Testo interface function for direct data transfer of measuring values to industry/customer-specific software*
  • Ready to use straight away: in standby mode, the testo 300 is ready to measure at the touch of a button. Use it straight away with the next customer – because you no longer need to wait for the end of the zeroing phase
  • Integrated Bluetooth® interface: immediate printout of the measuring values on site with the appropriate printer

*Note: the manufacturer has to integrate an interface into the industry software to use the function


Other advantages

  • 10-hour rechargeable battery life: an average measurement period of 2 hours means the flue gas analyzer is capable of being used for one week
  • Integrated, extra-strong magnets for easy fixing during the measuring process
