testo 300 LongLife Combustion Analyzer - Commercial Combustion Analyzer with Printer (w/ O2, CO 0-4,000, and NO Sensors)

0564 3004 94
  • Fast and easy to operate: intuitive measurement menus and fast-response Smart-Touch display
  • Includes O2 and CO Sensor (CO Sensor range 0-4,000ppm), NO Sensor installed
  • High-quality sensor technology with up to 6 year sensor life expectancy
  • Large 5-inch Smart-Touch HD display – see all the system's measurements at a glance
  • With this kit, you will be equipped for the most important measurements involving heating systems: the testo 300 combustion analyzer is supplied with O2, CO (range up to 4,000 ppm), and NO sensors, combustion probe, rugged hardshell case, printer, and practical accessories.
    Impressive measuring technology and quality
    • O2 sensor and CO sensor up to 4,000 ppm
    • NO sensor included
    • Longer sensor service life thanks to automatic sensor protection
    • Integrated draft and gas zeroing without removing the probe – the 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
    • 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
    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 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 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 on a full charge
    • Integrated, extra-strong magnets for easy fixing during the measuring process
