DatasheetThe testo 300 SE flue gas analyzer with Longlife sensors is ideal for chimney sweeps carrying out measurements in accordance with the 1st BImSchV. It combines decades of measurement technology experience with modern smart-touch operation, robust workmanship, and report sending by email or direct transfer of measurement results into industry software (interface integration by the software manufacturer required). With the testo 300 SE Longlife you can easily measure flue gas, draft, pressure, ambient CO and differential temperature.
testo 300 SE Longlife flue gas analyzer with smart-touch operation – equipment
Impressive measurement technology and quality
- O2 sensor and H2-compensated CO sensor up to 30,000 ppm thanks to the integrated fresh-air dilution
- NO sensor can be retrofitted
- Longer sensor service life thanks to automatic sensor protection
- Integrated draft and gas zeroing without removing the probe – the flue gas probe can remain in the chimney during zeroing
- For intensive daily use: high-quality Longlife sensors for O2 and CO with a service life of up to 6 years. This eliminates at least one sensor replacement during the typical service life
- TÜV-tested according to 1st BImSchV and EN 50379, Parts 1–3
- Integrated fine draft pressure and 4 Pa measurement for legally required measurements
- Up to 5 years manufacturer warranty on the O2 and CO sensor with product registration – without a maintenance contract
- Versatile probes and fast probe changes: benefit from quickly interchangeable probes and the multifunction handle for attaching various probe shafts (each available separately). Use e.g. longer probe shafts for larger-diameter flue gas ducts or flexible probes for hard-to-reach measuring points
- Optional probes and accessories for additional measuring tasks such as gas flow pressure measurement, gas line testing, differential temperature measurement, ambient CO measurement
Smart, intuitive, efficient: easy operation in everyday work
- Smart-touch display for intuitive operation of the flue gas analyzer: the display responds without delay – just as easy as on your smartphone
- Faster to the measurement result: clearly structured measurement menus for all relevant measurements
- Create documentation (incl. measured values, measuring location, customer data) easily on site
- Save PDF measurement reports directly on the device and always have them available
- Signature function: your customer can sign measurement reports directly on the device
- Send measurement reports by email via Wi-Fi (hotspot) directly to the office or to customers
- Large 5-inch HD display – so you can see all system parameters at a glance
- Testo Interface function for direct transfer of measured values into an industry-/customer-specific software*
- Ready for immediate use: in standby mode, the testo 300 SE is ready to measure at the press of a button. Use it right away at the next customer – no waiting for the zeroing phase
- Integrated Bluetooth® interface: print measured values on site with a compatible printer
*Note: To use this function, an interface must be integrated into the industry software by the manufacturer
Additional benefits
- 10-hour battery life: with an average measuring time of 2 hours, the flue gas analyzer can be used for a week
- Integrated extra-strong magnets for easy attachment during the measurement process
