3,the operating voltage: DC 3-5V 4, Feature: 1, with signal output instructions; 2, Dual-channel signal output (analog output and TTL electrical level output); 3, TTL output valid signal for low electrical level, can be directly by single chip microcomputer;
4, Analog output 0 ~ 5 v voltage, the higher the concentration, the higher the voltage
5,better sensitivity for liquefied petroleum gas, methane, coal gasification
6, Has a long service life and reliable stability
7,Quick response recovery features
Suitable for family or factory gas leakage monitoring device, suitable for liquefied petroleum gas, methane, coal gas, such as monitoring device, can test liquefied petroleum gas, methane, coal gas, 300 to 5000 parts per million (PPM) range.
