We have several varieties including: handheld particle counters in 3 and 5 channel versions; 6-channel portable particle counters with up to a 50LPM flow rate; a highly specialized condensation particle counter that features a 0.015 micron sensitivity making it ideal for Nano-sized particle counting; and a fixed cleanroom monitoring system that can be integrated with a PC for 24/7 monitoring.

We have a guide on selecting the right particle counter that you can download for free on our website:

This guide will explain the main differences between the handheld and portable particle counters and will help you choose the right one for your needs.

Yes, all our instruments come with a calibration certificate.

Annual calibration is recommended to ensure accuracy. However, this can vary based on how often the particle counter is used and the environments it’s used it. Also, some companies have an SOP in place that specifies how often the instrument will need to be serviced. More specifically, regulatory compliances may dictate the calibration interval.

Absolutely. Just make sure you select a counter that can measure the specific sized particles you need to measure. Handheld model 3887 and portable models 3900 & 3910 are pre-programmed with helpful standards modes that simplify the certification process.

Our portable units are 21 CFR part 11 compliant, and an IQ/OQ is available for purchase if needed.

Validation executed as a global exercise, is a method of establishing documented evidence that shows that we have a high degree of assurance that our manufacturing process will consistently yield a product of predetermined. If a manufacturer fails to do that, the results can be disastrous. It can cost the client hundreds of thousands of dollars, increase the risk of product recall and potentially contribute to a loss of market share.

No, you don’t need a separate instrument. Model numbers 3886, 3900 & 3910 can measure these parameters just by adding optional probes to the particle counter.

Yes, in addition to our handheld and portable units we have a permanent cleanroom monitoring system that can be installed in the cleanroom for 24/7 monitoring. Because each application is unique with its needs and challenges, we suggest you give us a call if you have questions or would like help designing a system for your cleanroom.
