Detects low-concentration gases with noticeable changes in electrical signals.
Rapid alteration of semiconductor electrical conductivity upon gas adsorption enables quick detection.
Detects most volatile organic compound (VOC) vapors.
Simple structure, low manufacturing cost, and stable long-term performance, making it suitable for cost-sensitive scenarios.
The JT-AT2004BII is specifically designed to detect combustible CH4 (Methane) gas.
The 2-wire design integrates both the power supply and signal transmission into a single bus layout. This eliminates the need for an external 24V power supply, simplifying the installation wiring and significantly reducing overall setup costs.
It utilizes advanced temperature compensation technology to dynamically adjust detection parameters based on the ambient temperature. This ensures stable and highly accurate gas detection while preventing false or missed alarms.
The detector is constructed from V0-rated flame-retardant material and features an IP31 protection rating, making it resistant to dust and light water splashes.
The typical lifetime of the detector is 5 years. It is equipped with an automatic lifetime expiration reminder to ensure that you are alerted when the equipment needs replacement to avoid potential safety risks.
Yes, the device features a built-in black box that automatically records alarms, operational faults, and logs to allow for quick and effective troubleshooting.
