APMON II Sensor
The APMON II particle deposition sensor measures real-time particle deposition rates for particles larger than 15 um. It counts every 4 minutes the number of particles that are deposited on a 50 cm2 test surface and measures their sizes.
The sensor can be used in two types of systems APMON 2 and APMON 1.5.

Description
How does it work?
APMON sensors collect 24/7 real-time data on the use of your clean controlled environment. They provide data on the deposition of airborne macro-particles. Light scattering airborne particle counters do not predict which particles can deposit onto surfaces. APMON II counts and sizes particles larger than 15 micrometers up to fibres of a millimeter and the moment these were deposited.
Particle deposition data show when and how much your product or process is at risk, the performance of your cleanroom and what can be done to improve the operational quality and to reduce risks.
Through AWS and a secured data transfer protocol, the data from different locations can be viewed simultaneously. Multiple locations and sensors can be linked together. This makes it easy to monitor and benchmark different processes and production locations of your company worldwide.
APMON II can be used in clean environments, cleanrooms and clean zones with personnel where particle and/or microbial contamination are important. Typical cleanroom classes are ISO 5, 6, 7 and 8 in operation. In these environments the way a cleanroom is used has impact on particle deposition rate.
In mini-environments and in process equipment where the air cleanliness is lower than ISO 4 the particle deposition rate is in most cases too low to determine the particle deposition rate within 24 hours.
Potential industries are: automotive (combustion/electrical motors, batteries, gear boxes, sensors and actuators), aerospace, assembly of electronics, displays, optics, MEMS and medical devices, clean machines for semiconductor and UHV, healthcare, hospitals, preparation of medical devices and instruments, etc.
Measures to control surface cleanliness are:
- Limit introduction of particles in the clean environment
- Avoid unnecessary surfaces inside the clean environment
- Ventilate the clean environment with a sufficient volume rate of filtered air
- Clean all surfaces frequently in a systematic manner, check cleaning efficiency using the SUMON.
- Monitor the surface cleanliness using the SUMON
- Monitor the resulting particle deposition rate using the SUMON or for real-time monitoring the APMON
