Product Description
This product is retired and we won’t sell it anymore. This page is for reference only.
Gas sensor MQ9 detects the presence of CO (Carbon Monoxide), CH4 (Methane) and LPG in the air. The best results are given while compounds are in liquid form, however, it still does an amazing job when measuring in gas form. It needs a bit of time to warm up in order to work correctly.
