Testo 300 Flue Gas Analyzer (O2, CO up to 4,000 ppm)

The Testo 300 Flue gas analyzer is truly a smart flue gas measurement instrument for use on heating systems. High-quality sensors, intuitive operation with smart-touch technology and smart features, such as efficient documentation and e-mailing of reports, The Testo 300 will make your day-to-day work easier.

Testo 300 flue gas analyzer with smart-touch operation

Impressive measuring technology and quality

• O₂ sensor and CO sensor up to 4,000 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
