For customers looking to purchase a methane sensor module, we have compared the company's various methane (CH4) sensor modules by feature.
There are 3 types as % LEL sensing, low concentration sensing up to 5,000ppm, high-concentration up to 100 vol % sensing.
A low-cost single sensor is newly developed for the% LEL sensing type.
You can quickly select the model you want to purchase by looking at the comparison chart.
Details can be found in the data sheet on the product introduction page.
