Product overview:
SM3571M smoke sensor is imported high sensitivity smoke sensor as the core device of high precision detection, qualitative measurements can be performed on a wide range of 100PPM smoke; has a wide measurement range, good linearity, convenient use, convenient installation, long distance transmission, which is suitable for various places. The probe can be used for measuring smoke, smoke and so on. Due to the use of electrochemical testing core devices, it is generally used for qualitative testing. This product is specially designed and easy to replace. Because the probe is a fragile product, the machine is free of charge except the probe for one year.

Measure current I, range A and smoke reference value V relation:
V= A* (I-4) / (20-4)
If the current measured current value is 8mA, the range is 5000ppm, then the current smoke concentration is calculated as:
V=5000* (8-4) / (20-4) =1250, or 1250ppm.
Because the core of the product is electrochemical value device, because of the difference of smoke concentration and electrochemical core, the above concentration is only used to measure the relationship between current I, range A and smoke reference value V:
V= A* (I-4) / (20-4)
If the current measured current value is 8mA, the range is 5000ppm, then the current smoke concentration is calculated as:
V=5000* (8-4) / (20-4) =1250, or 1250ppm.
Because the core of the product is an electrochemical value device, because of the difference in the concentration of smoke and the electrochemical core, the above concentration is for reference only and is used for qualitative detection.
