Portable particle counters for cleanroom certification

Kanomax Portable Particle Counters – Models 3905 and 3910 are the smallest 6-channel portable particle counters in the industry. They measure at 1.0 CFM (28.3 LPM) and 1.77 CFM (50 LPM), respectively. Both models feature 0.3-micron minimum sensitivity, large color touch screens with a streamlined and user-friendly interface programmed with different standards to help guide users through the measuring and certification process.

An optional Climomaster hot-wire environmental sensor is available. It provides the ability to measure air velocity, temperature and humidity, making the 3900 series portable particle counters the ultimate tools for cleanroom certification.

Beyond their power and diversity as measuring tools, they are also extremely lightweight, small and incredibly easy to transport. They are fully compliant with ISA 21501-4 calibration standards and they enable you to certify cleanrooms up to ISO Class 2. Again, the multi-standard modes simplify cleanroom certifications based on ISO 14644, FS 209E, BS 5295 and EC GMP, which make the measuring process simple and offer you peace of mind when measuring for specific results.

There is a built-in printer and onboard data logging memory that stores up to 10,000 records at a time. The lightweight enclosure is stainless steel and absolutely cleanroom friendly, and the diverse offering of options (including the differential pressure sensor and optional second Li-Ion battery for extended operating time) truly make these portable particle counters the most powerful cleanroom measuring instruments on the market.

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:

DOWNLOADThis 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.

You can measure clean air between -4 and 158°F (-20 to 70°C) in an environment with no visible condensation. (Please note: the temperature range given is for the probes)

Windows XP (32-bit only), Vista, & Windows 7.

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.

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.

It includes: AC adapter, zero filter, isokinetic probe with 79″ of tubing, inlet nozzle, data processing software, memory card, 2 rolls of clean printer paper, 1 x Li-ion battery and calibration certificate.
