for power input, the machine should be grounded safely through the grounding
terminal.
9. When the terminal wiring and plug in terminal or other operation are done, it is
necessary to disconnect the power supply and operate.
10. The interval between instrument power failure and power on again is more
than 5 seconds.
I. Product introduction:
AQM-09 is a new product which can monitor the air quality via the value of O3,
SO2, NO2, CO, PM2.5, PM10, etc. The target value is converted into voltage
signal by operational amplifier circuit, and then filtered through high-precision
AD data acquisition system. Finally, the gas concentration is calculated by CPU.
Particulates mainly use laser scattering method to produce different scattering
light according to different particle diameters under laser scattering conditions.
The scattered light intensity is collected by a response device, and the particle
