Liquid particle counters are essential for critical measurement of ultrapure water and pure process chemicals within semiconductor and other precision manufacturing industries. Whether semiconductor, aviation, pharmaceutical, or sensitive component manufacturing, controlling purity in both air and liquid is a requirement for maintaining high-quality products with maximum yield. Particle Measuring Systems manufactures particle measurement equipment to the highest industry standards, and is particularly suited for ensuring precision control in cleanroom environments.

Our industry-leading liquid particle counters provide you with reliable particle counting in DI and UPW water, as well as chemicals, to 20 nm. Choose from a variety of sensitivity ranges and mediums to find the right solution for your application. 

Liquid particle counters are essential for critical measurement of ultrapure water and process chemicals within the semiconductor and other manufacturing industries. Whether semiconductor, aviation, pharmaceutical, or sensitive component manufacturing — monitoring contamination in both air and liquid is a requirement for maintaining high-quality products with maximum yield. Particle Measuring Systems (PMS)  manufactures particle measurement equipment of the highest industry standard and is particularly suited for ensuring precision control in cleanroom environments.

Liquid Particle Counters & Why They Are Beneficial

A particle counter detects physical particles present in both ultrapure water and high purity process chemicals.  Controlling contamination within these critical liquid process streams is essential to maintaining clean and profitable manufacturing facilities.  Critical liquid particle counters are necessary to engineer clean chemical and water systems, as well as maintain these systems in production environments. To receive proper classification, a dedicated cleanroom must meet defined particle count limits.

Liquid Particle Counting System

Particle counters have a variety of cleanroom applications. Our liquid particle counters can determine the size, amount, and nature of particulates in liquid substrates, computer components, medical devices, sensitive equipment, or an assortment of other precision devices. Liquid particle counting systems are also able to determine the overall quality of a liquid substrate; both particulate quantity and size are important for determining the cleanliness of cleaning solutions, liquid pharmaceutical products, foods, oils, fuels, and lubricants, or various other systems where contamination must be prevented.

Liquid Particle Counting Applications 

Liquid particle counters have a variety of clean manufacturing applications. Combined with our global team of application experts, we can help you control contamination in a variety of applications and locations including :

  • chemical quality assurance in distribution, delivery, or packaging systems
  • Point-of-process monitoring
