Truly smart flue gas measurement on heating systems with the testo 300 flue gas analyzer. High-quality sensors, intuitive operation with smart-touch technology and smart features, such as efficient documentation and e-mailing of reports, will make your day-to-day work easier.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. |Testo interface function for direct data transfer of measuring values to industry/customer-specific software*. *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
