1.How to calibrate a methane sensor?
Our methane sensor has been calibrated before delivery, and can be used directly after installation without the need for secondary calibration.

2.How do I buy a methane sensor?
Please confirm the model number and shipping address with the salesperson via message or online chat. After payment, we will deliver the goods within 24 hours.

3.Cross interfering gas
This sensor uses catalytic combustion for measurement, so it can be considered that all combustible gases with similar characteristics are cross-interference items. For example, for all types of alkanes, the LEL value combined with the lower explosive limit can be used to calculate the gas concentration.
It should be noted that many combustible gases are the interference items of this sensor, but it cannot be considered that this sensor can measure all combustible gases. This sensor is to measure combustible gases based on alkane, please consult the technical support of the company whether other combustible gases can be detected.


1. What is a methane sensor?
A methane sensor is a device that measures the concentration of methane in the environment and usually has an alarm function. Once the concentration exceeds the limit, an alarm will be raised.
2. What type of sensor is used to detect methane gas?
There are usually three types of wall-mounted methane sensor, portable methane detector and stationary methane detector, depending on the different use environment.
