Testo 327-1 Standard Kit with Gas Leak Detector
The Testo 327-1 Standard Kit with Gas Leak Detector gives engineers a reliable way to measure flue gas values and check for gas leaks during servicing work. It measures O2 and CO levels while also supporting draught and pressure checks. The compact design helps users work safely and quickly across many heating systems.
Built for natural gas, LPG, kerosene and light oil systems, the analyser delivers accurate readings during daily testing. The Testo 327-1 Standard Kit with Gas Leak Detector also includes a rechargeable battery with up to five hours of operation. In addition, the clear 4-line LCD display allows readings to stay visible in low light areas.
Reliable Gas Analysis
Fast response times help engineers complete servicing tasks with less delay. The analyser measures CO from 0 to 4000 ppm and supports temperature readings from -40 °C to 600 °C. Furthermore, the built-in condensate trap helps protect the unit during regular use.
Gas leak detection adds another level of safety when working around boilers and pipework. The detector identifies methane, propane, butane and hydrogen leaks with both visual and audible alarms. As a result, the Testo 327-1 Standard Kit with Gas Leak Detector supports safe working practices in domestic and commercial settings.
Designed for Daily Use
Easy menu navigation allows users to move through settings without confusion. The lightweight body and soft carry case improve portability between jobs. At the same time, the single probe connection speeds up setup before testing begins.
Long warranty coverage provides extra confidence for engineers and contractors. The analyser includes a 3-year sensor warranty and a 3-year analyser warranty. With support for multiple fuels and simple report printing, the Testo 327-1 Standard Kit with Gas Leak Detector is suitable for routine heating inspections and maintenance work.
