Do you know how many common methods are used for testing clean rooms?

The testing methods for clean rooms mainly include the following:

1. Air particle detection: By setting sampling points at different locations, air samplers are used to collect particles in the air, and laser particle counters or resistive particle counters are used to measure the number and size distribution of particles.

2. Air flow velocity detection: Use an air flow meter or smoke detector to measure the air flow velocity to ensure that the air flow in the clean room meets the specified requirements.

3. Temperature and humidity detection: Use temperature and humidity sensors to measure the temperature and humidity in the clean room to ensure that the environmental parameters in the clean room are within the specified range.

4. Static electricity detection: Use an electrostatic tester or electrostatic potentiometer to measure the static electricity field strength in the clean room to ensure that the static electricity level in the clean room meets the specified standards.

5. Harmful gas detection: Use a gas analyzer or multi parameter gas detector to measure the concentration of harmful gases in the clean room to ensure that the air quality in the clean room meets the specified requirements.
