REMS 610050 FG4500 C Set Flue Gas Analyser

The REMS 610050 FG4500 C Set is a compact flue gas analyser that tells you exactly what's happening inside a boiler or heating system's exhaust gases, so you can check it's burning safely and efficiently. In plain terms: you connect the probe to the flue and the device reads the gases coming out and checks the system pressure, telling you whether the appliance is working as it should. It's the kind of test a Gas Safe engineer or heating technician needs for servicing boilers, checking new installations and routine safety testing on drinking water, heating and gas installations.

Weighing only 425g, it's built for genuine one-hand use, with a sturdy, impact-resistant housing and a clear 3.5" touchscreen that walks you through each test step by step, so you're never guessing what to do next. The gas cartridge sits behind a large viewing window with quick-release catches, so cleaning the condensate tank or swapping filters takes moments rather than minutes. Results can be saved, logged, or sent straight to your phone or laptop over Bluetooth or USB using the free REMS mCon app. Backed by REMS's manufacturer warranty, extendable to 2 years with free registration at rems.de/service.
