Robust, fast-action flue gas analysis for all key parameters
The Testo 327-1 is an introductory flue gas analyser measuring combustion efficiency, temperature, O2, CO2, CO and flue draught. A strong LED backlight in the 4-line display guarantees easy-to-read results even in unfavourable lighting, while easy menu navigation and an ergonomic, durable housing make it dependable in daily use.
The Testo 327-2 service analyser adds a data store for 20 measurements, differential temperature measurement for flow and return, and differential pressure measurement to adjust pressure ratios in gas systems. An optional H2-compensated CO sensor enables official measurements on gas burners in accordance with EN 50379 Part 2.
With gas sensor life expectancy up to three years, instrument and sensor diagnosis, and IR and IrDA interfaces for printing and data transfer, the 327-2 combines performance with long-term reliability.
