The Testo 327-1 combustion flue gas analyser is extremely robust and simple to use. Ideal for installation, commissioning, service and maintenance on all types of boilers and burners, tt measures combustion efficiency, °C, O2, CO2, CO and flue draught. The Testo 327 features simple to follow menus, a large 4 parameter display and fast startup (stable readings available within 30 seconds).
The tough, ergonomic design features a shock-proof elastomeric protection skin and modular probe connection system which is compatible with the Testo 330 range of probes.
