Airy Technology P611 Particle Counter

The Airy Technology P611 Handheld Particle Counter is a 6-channel particle counter, measuring particle sizes from 0.3 to 10.0 μm. The P611 allows the user to specify each channel size prior to delivery of the P611. It features automatic flow control and a flow rate of 0.1 CFM (2.83 LPM). It also features optional temperature and relative humidity measurement capabilities with the addition of a compatible Temp RH probe. The Airy P611 is compact and lightweight, and makes an excellent choice for a handheld particle counter for field or laboratory use.

The P611 particle counter can store up to 10,000 sample measurements and 999 sample locations. It has a sampling time range of 1 second to 99 minutes and 59 seconds (time span of a single sample). Sample frequency can be set from 1 to 9999 cycles (amount of samples taken in one test). The Airy P611 features six different sampling modes: Manual, Automatic, ISO, GMP, Cumulative/Differential, and Count/Concentration.

  • Manual mode allows for the user to stop gathering measurements at the push of a button.
  • Automatic mode allows for the user to enter a sampling time and a frequency that dictate how many samples will be taken before the P611 stops on its own.
  • ISO calculates standard deviation, average, and 95% UCL. The user must input the area of the clean room and the P611 will calculate the minimum amount of sampling locations and the amount of sampling time for each location. Validates class 5-9 at 0.3-5.0 μm, excluding 5.0 μm.
  • GMP calculates minimum sampling time, minimum sampling locations, and minimum frequency. This mode validates grade A-D in operation and A-C at rest.
  • Cumulative/Differential will produce the amount of particles equal to or larger than the desired size and the number of particles between the desired size and the next larger size.
  • Count/Concentration will accumulate and update the data every six seconds. This mode must be manually stopped.

The P611 meets ISO 21501-4 and JIS B9921 standards. The P611 is calibrated to NIST traceable standards. It also reports ISO 14644-1 and EU GMP. The P611 can export measurements through a USB cable to a PC with the included data download software. It is equipped with an alarm that will alert the user of broken count ranges, low battery, and flow and laser status. The long life laser diode ensures years of accurate service from the Airy P611 particle counter.
