1. The core component gas sensor is different (main difference): the combustible gas alarm uses a catalytic combustion gas sensor; the toxic gas alarm uses an electrochemical toxic gas sensor.
Expansion description: If it is to detect toxic gas, the sensor needs to be one-to-one, because different toxic gas sensors are different, such as ammonia, chlorine, hydrogen sulfide, and other common toxic gases.
If it is to detect combustible gas (flammable and explosive gas), the sensor can be universal, but the calibration coefficient of each combustible gas is different. Different combustible gases have different chemical characteristics and different explosion limit values. Therefore, the professional gas alarm manufacturer Oceanwide Technology will set different alarm values according to the different gases provided by the customer. If you do not know the gas explosion limit value, just You only need to provide the gas name of your testing site, and we will calibrate and calibrate it according to the lowest gas to ensure that the area is safe.
2. The display concentration unit is different: the display unit of the combustible gas alarm is %LEL; the display unit of the toxic gas alarm is PPM.
3. The detection space range is different: the detection radius of the combustible gas alarm is about 7.5m; the detection radius of the toxic gas alarm is about 1.5m.
In addition, because the gas sensors used for combustible gas and toxic gas are different, their core technology (program) and circuit board are also different.
Except for the main differences above, there is no difference. The appearance of the combustible gas alarm and the toxic gas alarm are basically the same, both of which are over-standard alarms. Maybe the customer has questions about how the product with so many gases is an appearance, because there are hundreds of kinds of gases, if it is impossible and unrealistic to make an appearance for each gas, this will help improve the production efficiency of gas alarm manufacturers and save money. Shell mold costs, thereby shortening the customer's customization time and reducing the customer's purchase cost.
