This is the standard 180mm replacement or spare probe for the Testo 300 series flue gas analysers — the probe that goes into the flue to sample combustion gases. A bayonet lock connection attaches the probe to the analyser and makes three connections at once: the sample gas path, the draught measurement path and the temperature thermocouple, all from a single coupling action without separate hose connections.
An integrated particle filter in the handle protects the analyser's sensors and pump from contamination, and can be changed in the field without tools once it becomes blocked. The 180mm length suits standard domestic and small commercial boiler flue ports; for large commercial combustion plant with longer flue test points, the 300mm version (0600 9741) gives deeper insertion.
Key Features & Benefits
Bayonet Lock Single Probe Coupling: Connects flue gas path, draught path and temperature thermocouple to the Testo 300 analyser simultaneously in one coupling action.
NiCr-Ni Thermocouple, Tmax 500°C: Integrated temperature measurement within the probe shaft.
Integrated Particle Filter, Tool-Free Replacement: Protects the analyser's gas paths and sensors from contamination.
180mm Probe Shaft, 6mm Diameter: For standard domestic and light commercial boiler flue ports.
1.5m Hose: Practical reach for standard installations.
For Testo 300 Series Flue Gas Analysers: Compatible fit across the range.
Which Probe Length Do I Need?
0600 9740 – 180mm (this product): For standard domestic and light commercial boiler flue ports.
0600 9741 – 300mm: For large combustion plant and industrial flue test points requiring greater insertion depth.
Ideal For
Replacing or adding a spare probe for the Testo 300, Testo 300+, Testo 300 LL or compatible 300 series analysers.
Domestic gas and oil boiler servicing.
Why Buy This Product?
The bayonet lock connection making three separate connections in one action genuinely saves time when swapping or reconnecting a probe on site, rather than fiddling with separate gas, draught and temperature connections. The tool-free filter replacement keeps routine maintenance quick, and choosing the correct length between this 180mm version and the 300mm alternative matters for getting proper insertion depth at the specific flue test point being worked on.
