Product Description

Carry out installation and maintenance work on heating systems several times a

day using the flue gas analyzer with Longlife sensors. The TÃœV-tested testo 300

Longlife flue gas analyzer is supplied with O2 and CO H2-compensated sensor up to

30,000 ppm (NO – can be retrofitted), TÃœV-tested modular flue gas probe, case and

practical accessories.

Testo 300 Longlife flue gas analyzer 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

  • TÃœV-tested according to first German Federal Immission Control Ordinance

    (BImSchV) and EN 50379, Parts 1-3

  • Integrated fine pressure and 4 Pa measurement for legally prescribed


  • 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, customer

    data) easily on site

  • Save PDF measurement reports directly in the instrument and always have them


  • 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


  • Large 5-inch HD display – enables you to see all the system’s parameters


  • 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

    • Integrated dirt filter protects instrument and sensors
    • Integrated thermocouple probe for temperature measurements up to 500


    On the TÃœV-tested modular flue gas probe with 180 mm long probe shaft, the flue

    gas path and temperature channel can be conveniently connected to the measuring

    instrument via a practical bayonet lock. The probe shaft is also easy to replace,

    thanks to the quick-change click system on the handle. The thermocouple NiCr-Ni,

    which is integrated in the probe shaft, enables temperature measurement up to 500

    °C. In addition, a dirt filter protects the instrument and its sensors from

    • Pack of 10 spare particle filters
    • Easyheat PC analysis software

      • Easyheat PC analysis software, shows measurement in form of diagrams, tables and

        manages customer data.

      • Easyheat allows the management of data obtained with the testo 330 and testo 330

        LL, and the corresponding customer and measurement site data, on a PC. The

        measuring instruments testo 330 and testo 330 LL can be configured via easyheat.

        The necessary settings of the measuring instrument can thus be carried out at any

        time directly from the PC.
