Air ion tester installation
- It can be installed and fixed with screws. The dimensions of the mounting holes are as follows (unit: mm): Note that the device must be placed vertically, otherwise, it will affect the accuracy of the data.
- The installation needs to be stable, and the height between the center of the detector and the ground should be 1.5m.
- The shell and outer box of the collector should be well-grounded.
- With lightning protection facilities, the grounding resistance should be less than 4Ω.
- A protective fence can be optionally set up, the height of the fence should not exceed 1.2m, and the distance between the instrument and the fence should be greater than 2.0m.
- Wide voltage power input can be 10~30V. When wiring the 485 signal line, pay attention to the two wires A\B not to be reversed, and the addresses of multiple devices on the bus can not conflict.
Negative ion tester application
A negative oxygen ion detector can monitor air negative oxygen ions for forestry, environmental protection, meteorology, tourism, etc. It improves the air in rural and urban areas and is of great significance to human society.
