1. Temperature and environment
Ethernet Testers are good and can accommodate poor temperature and humidity.
Ethernet switches are highly selective in their components, so they are well suited to harsh environments.
3, the electromagnetic
Lan Network Testers have a strong ability to resist electromagnetic interference.
General switches are single power, industrial switches are generally double power backup.
Industrial switches are well protected against adverse conditions such as high impact, corrosion, water and dust resistance.
6. Body heat dissipation
Common switches use fans to dissipate heat, while Ethernet switches use a fanless enclosure to dissipate heat.
