FAQ

Here you can learn about the selection guide, common technical problems, packaging, transportation, MOQ, delivery time, etc.

Can the Catalytic Sensor Be Made into a Digital Display?

MC series catalytic products have good linearity and can be made into digital display products.

All the Mc Series Products Measure Combustible Gas, What is the Difference?

MC series products are different in power supply voltage and current, their appearance and structure are also different; in addition, they are divided into two types: domestic and industrial. Industrial products require explosion-proof and the shell should be the explosion-proof structure of metallurgical powder mesh. The MC100 series is mainly used for domestic use, and the MC110 series is mainly used for industry.

What is the Reason for the Early Warning of the Catalytic Sensor?

The sensor has a long cooling time and insufficient aging. The test conditions and environmental conditions for inspection and calibration are different. The vibration during use causes the zero point changing. It is activated by high-concentration gas during use, then the sensitivity becomes higher.
