Testo 300LL ‘Longlife’ set with NOx + Printer

The testo 300 flue gas analyser with Longlife sensors is ideal for heating engineers who carry out installation and maintenance work on heating systems several times a day. It combines decades of experience in measuring technology with contemporary Smart-Touch operation, robust construction and e-mailing of reports. The testo 300 enables easy measurement of flue gas, draught, pressure, ambient CO and differential temperature. This kit includes a factory fitted NO sensor for NOx measurement.

Truly smart flue gas measurement on heating systems with the testo 300 flue gas analyser. 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

• O_2, H₂ - compensated CO sensor up to 30,000 ppm thanks to integrated fresh air dilution and NO sensor
• 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
• Designed and tested to compliance of EN 50379, Parts 1-3
• 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 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 and 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

• 10-hour rechargeable battery life: an average measurement period of 2 hours means the flue gas analyser is capable of being used for one week
• Integrated, extra-strong magnets for easy fixing during the measuring process
