Testo 327-1 Standard Kit with Gas Leak Detector and CPA1 Kit
The Testo 327-1 Standard Kit with Gas Leak Detector and CPA1 Kit gives engineers a reliable way to test and monitor combustion systems. It measures O2 and CO levels while also checking gas pressure and draught conditions. In addition, the included gas leak detector helps identify methane, propane, butane and hydrogen leaks during servicing work.
Built for use with natural gas, LPG, kerosene, heavy oil, light oil and wood pellets, this analyser supports a wide range of heating systems. The 4-line LCD screen keeps readings clear and easy to follow during testing. Rechargeable battery power also supports long working periods in the field.
Reliable Combustion Testing
With the Testo 327-1 Standard Kit with Gas Leak Detector and CPA1 Kit, engineers can carry out combustion checks with confidence. The unit supports differential temperature and draught measurements while maintaining stable readings. Separate AT temperature measurement and ambient CO testing also improve flexibility during servicing tasks.
The included CPA1 accessory kit allows use with flueless combustion appliances such as grills and cookers. As a result, the analyser can support fume investigations and appliance checks in catering environments. Fast probe connection and simple menu navigation also help reduce setup time.
Designed for Daily Use
Engineers can store readings and produce IR printouts directly from the analyser during servicing work. The built-in condensate trap helps protect the unit in demanding conditions, while the LED display light improves visibility in darker plant rooms. A soft carry case and shoulder strap also make transport easier between jobs.
Testo 327-1 Standard Kit with Gas Leak Detector and CPA1 Kit includes a durable analyser backed by a 3 year analyser warranty and 3 year sensor warranty. EN 50379 compliance supports professional testing requirements for O2 and CO measurement. Combined with the included probes and gas leak detector, this kit provides a complete combustion testing solution.
