The PCE-PQC 21EU series air particle counters are portable detection systems that include particles of specific sizes in the air. Furthermore, the air temperature and the relative humidity are monitored. The fixed flow rate of 2.83 l / min complies with current standards for air particle counter ISO 21501-4 and JIS B9921. Due to the compact design, the air particle counter of the PCE-PQC 21EU series can be used in a variety of ways. These include the monitoring and inspection of clean rooms, filter systems in operating theaters and bottling plants in the pharmaceutical industry.
The internal memory of the air particle counter is sufficiently large for up to 45000 data sets. These data sets each include the metering parameters, temperature and humidity sensor readings, locations, and timestamp. An optionally available printer enables the measurement results to be printed directly. On the other hand, the stored data records of the air particle counter can be read out and processed via the supplied software via Ethernet, USB or Wifi.
