1 CFM Portable Airborne Particle Counters

The CI-150 Series of 1 CFM airborne particle counters are engineered with highest quality materials. This ensures a long product life-cycle, and up to decades of reliable use. Moreover, lifetime calibration support services are offered on all our instruments.
Accuracy & Reliability
All our particle counters are engineered to exceed ISO Standards for accuracy. 50% Count Efficiency on factory-new and interval calibrations are calibrated to ± 10%, rather than the looser ISO standard of ± 20%. 100% Count Efficiency is calibrated to meet the ISO Standard of ± 10%.
We have built our reputation by providing highly accurate instruments that stand the test of time. An internal study conducted in 2014 confirms that particle counters returned for calibration over the past two years have an “In Tolerance” calibration rate of ninety-eight (98) percent! This study also includes some units manufactured over 20 years ago.
Simply, Climet particle counters are engineered, tested and calibrated with tight tolerances to exceed industry standards. Years of count efficiency testing has demonstrated that a properly calibrated Climet particle counter produces good count efficiency, even after more than a decade of field operation!
Return On Investment
Not all particle counters are equal. The initial purchase price, cost of calibrations, cost of consumables, out of warranty repairs, and product life-cycle all factor into calculating the Return on Investment. Other intrinsic factors such as assurance, reliability, accuracy, application support, and superior customer service make Climet the unsurpassed leader in the manufacture of particle counters for cleanroom monitoring, validation, and certification.
