testo 300 combustion analyzer with smart-touch operation – Features

Impressive measuring technology and quality

O₂ sensor and CO sensor up to 4,000 ppm
Longer sensor service life thanks to automatic sensor protection
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 combustion 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 to 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 WiFi (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 right away: in standby mode, the testo 300 is ready to measure at the touch of a button. Use it right 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 combustion analyzer is capable of being used for one week
Integrated, extra-strong magnets for easy fixing during the measuring process
