Particle Counters

In the world of cleanroom technology, particle counters are essential. Although you take stringent steps to maintain the state of your cleanroom, without an air particle counter, it becomes nearly impossible to verify that your efforts were well spent or adhere to industry standards.

Fortunately, our particle counters are precisely engineered to meet the diverse needs of a range of cleanroom applications. In addition to handheld devices that can be used for on-the-spot measurements following spills and other incidents, we also carry a number of larger models geared towards routine assessment. All of our counters include digital display readouts and high maximum concentration levels, ensuring that your measurements will always be as accurate as possible.

Head down this page to learn more about the potential uses of this innovative cleanroom technology and find a device for your installation. Select an air particle counter with a USB interface, or choose something with an appropriate number of particle channels for custom measurement setups and more extensive validation testing. Add an optional temperature or humidity probe to create your own personalized, versatile device. To discover more about our cleanroom devices, browse around, or get in touch with one of our representatives.
