Testo 327-1 - The All-Rounder for Flue Gas Analysis
The Testo 327-1 is a Flue Gas Combustion Analysis tool built for heating engineers, plumbers and HVAC technicians carrying out commissioning, servicing and safety checks on heating systems. It measures oxygen, carbon monoxide, temperature and flue draught, and calculates carbon dioxide, combustion efficiency and flue gas loss — covering gas, oil, LPG and biomass appliances from one instrument. It's ready to give stable readings within around 30 seconds.
The display is a clear 4-line screen with a bright LED backlight, keeping results legible even in poor lighting. The housing is built for daily field use, with an ergonomic design and shock-proof elastomeric protection to handle the knocks of regular site work.
It also measures differential pressure, draught and temperature, includes an integrated condensate trap, and works with the full Testo 330 probe range via a quick-connect interface. It's independently tested to EN 50379 and certified to BS 7967, with automatic pump protection to guard the CO measuring cell against over-range damage.

Why Buy This Product?
Fast 30-second start-up and a clear 4-line backlit display keep servicing moving without unnecessary delay between readings, and the shock-resistant, elastomer-protected housing is built for the knocks of daily field use rather than careful bench handling. Compatibility with the full Testo 330 probe range via a quick-connect interface means the analyser can be extended for different measurement tasks without switching instruments, and EN 50379 testing with BS 7967 certification confirms it meets the standards needed for professional combustion analysis.
