FAQ
Can I use the GM8100 as a gas alarm detector at home?
Yes. It is a handheld detector for checking combustible gas leaks such as natural gas around boilers, hobs, meters and pipe joints. It is not a fixed alarm — keep your installed gas alarms.
How do I find a gas leak with it?
Switch on in fresh air and let it warm up for about 60 seconds. Then move the probe tip slowly along pipes, joints and valves; the alarm becomes active as gas concentration rises.
Is UK delivery free?
Yes. Free UK delivery, dispatched in 1–2 working days, delivered in about 5–7 working days. Prices include VAT. 30-day returns.
