With this kit, you will be equipped for the most important  measurements involving heating systems: the EN 50379, Parts 1-3  compliant testo 300 flue gas analyser is supplied with Oand CO sensor up to 4,000 ppm, basic flue gas probe, instrument case and practical accessories

testo 300 Longlife flue gas analyser with smart-touch operation – Features

Impressive measuring technology and quality

  • O2 sensor and H2-compensated CO sensor up to 30,000 ppm thanks to integrated fresh air dilution
  • NO sensor - can be retrofitted
  • Longer sensor service life thanks to automatic sensor protection
  • Integrated draught and gas zeroing without removing the probe – the flue gas probe can remain in the flue during zeroing
  • For intensive daily use: high-quality Longlife sensors for O2 and CO with a service life of up to 6 years. That means at least one  sensor replacement is saved in the course of a normal working life
  • Compliance with EN 50379, Parts 1-3
  • Integrated fine pressure and 4 Pa measurement for legally prescribed measurements
  • Manufacturer's warranty of up to 5 years on O2 and CO sensor with product registration – without a maintenance contract
  • 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, 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
