- Large 5-inch HD display shows all parameters immediately
- Testo interface allows direct data transfer to industry-specific software*
- Instant readiness from standby mode without zeroing delay
- Bluetooth® connectivity for on-site printing with compatible printer
*Note: Integration with industry software must be performed by the software manufacturer.
Additional Advantages
- 10-hour rechargeable battery allows up to a week of typical use (average 2-hour measurement sessions)
- Extra-strong integrated magnets for secure placement during measurements
For applications focused on essential combustion and flue gas efficiency metrics with robust probe options, the Testo 310 Combustion Analyzer Kit delivers reliable measurement of O₂, CO, CO₂ and draft parameters. In environments where standard residential and light commercial metrics are sufficient, the Residential/Commercial Combustion Analyzer Kit with Printer (O₂ and CO 0‑4,000 ppm) provides an effective balance of performance and value for routine flue gas analysis and compliance verification across diverse heating systems.
Q&A
What gases can the testo 300 measure?
It measures oxygen (O2) and carbon monoxide (CO) up to 4,000 ppm, and additional measurements are possible with optional probes.
Can it be used in tight or hard-to-reach flue pipes?
Yes, the analyzer supports quick-change probe shafts including flexible or extended-length probes for difficult access.
How is data documented on-site?
Measurements can be saved as PDFs, signed by customers, and emailed via WLAN, while direct software transfer is possible with the Testo interface.
How long does the battery last?
The rechargeable battery provides approximately 10 hours of continuous use, sufficient for multiple days of typical measurement sessions.
