    testo 300 flue gas analyzer with smart-touch operation – Features

    Impressive measuring technology and quality

    • O2 and H2-compensated CO sensor up to 8,000 ppm
    • 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, 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
