Testo 300 Longlife flue gas analyzer with smart-touch operation – Features

Impressive measuring technology and quality

O2, NO sensor and H2-compensated CO sensor up to 30,000 ppm thanks to integrated
fresh air dilution
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
TÃœV-tested according to first German Federal Immission Control Ordinance
(BImSchV) and EN 50379, Parts 1-3
Integrated fine pressure and 4 Pa measurement for legally prescribed
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 analyser:


    • 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


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
