Fits residential and commercial flue-gas work where you need a Testo 300 NEXT LEVEL smart-touch analyzer with O2/CO sensors and wireless Smart Probe parallel measurements.
Key advantages
- Smart-touch flue analyzer — Testo 300 NEXT LEVEL with responsive Smart-Touch colour display
- O2 / CO — O2 0–21 vol.%; CO up to 4,000 ppm base; Longlife/dilution options higher (to 30,000 ppm CO class)
- Accuracy — O2 ±0.2 vol.%
- Smart Probes — Wireless parallel measurement of up to four testo Smart Probes via Bluetooth Connector
- Reporting — On-site PDF/email via testo Smart App; optional NO / NOlow / COlow sensors
Typical applications
- Boiler and burner flue-gas tuning with guided menus.
- Parallel Smart Probe temperature/pressure measurements.
- On-site report generation via Smart App.
Selection guide
- Sensor set — O2/CO base vs Longlife; optional NO/NOlow/COlow
- Warranty class — 2-year vs 4-year Longlife offerings per OEM configs
- Probes / Smart Probes — flue probe length; 115i/510i/915i needs
- Documentation workflow — Smart App / QR / customer software interface
Common mistakes
- Assuming high-range CO dilution without ordering the matching sensor/config.
- Ignoring Smart Probe connector if parallel wireless measurements are required.
- Ordering without flue probe — probe kits are configuration items.
When to RFQ / what to tell us
- Sensor options (CO range, NO/NOlow/COlow, Longlife).
- Flue probe and Smart Probe needs.
- Quantity; ship-to.
