    Description

    Overview

    Accurate flue gas analysis is essential for ensuring heating systems operate safely, efficiently, and in line with industry standards. Whether commissioning boilers, conducting routine maintenance, or diagnosing combustion issues, reliable measurements are vital for effective service.

    testo 327 Standard Kit – Reliable and Robust Flue Gas Analysis

    The testo 327 Flue Gas Analyser Standard Kit is a dependable tool designed for domestic boiler servicing and combustion analysis. Delivering precise measurements of oxygen (O₂) and carbon monoxide (CO), it also calculates key values such as carbon dioxide (CO₂), combustion efficiency, and flue draught.
    The analyser’s bright 4-line LED display ensures clear visibility of readings, even in dimly lit environments, while intuitive menu navigation simplifies operation. The testo 327’s ergonomic design and durable housing provide added resilience for demanding on-site conditions.

    Fast, Efficient Testing with Practical Features

    The testo 327 achieves stable readings within 30 seconds, reducing waiting times and boosting productivity. An integrated condensate trap protects the device from moisture damage, while the automatic pump shut-off feature helps safeguard the CO sensor from saturation.
    For enhanced functionality, the testo 327 is compatible with an optional pressure testing adaptor, enabling engineers to carry out tightness and let-by tests directly from the analyser.

    Complete Kit for Heating Engineers

    The testo 327 Standard Kit comes equipped with a flue gas probe, mains power supply, and a protective soft carry case for safe storage and transport. Independently tested to EN 50379 and certified to BS 7967, the testo 327 offers accurate, compliant results for confident diagnostics.
    With its proven reliability, practical features, and robust design, the testo 327 Standard Kit is an ideal choice for heating engineers seeking a durable and efficient flue gas analyser.
