Air Sampler P611

Order no.: P611
P611 is a compact, highly accurate and user-friendly laser particle counter or air sampler designed in accordance to ISO 14644-1 and EU GMP guidelines (compatible to JIS B9921). This handheld laser particle counter measures 6 different particle sizes and offers cumulative and differential sampling modes. Choose the particle sizes relevant to your application by selecting the type (1-4; see specifications for details) from the drop-down menu when ordering.

A USB interface allows up to 10,000 saved measurement values to be transferred from the device's internal memory to a PC for detailed analysis and long-term storage. Thus, this laser particle counter is an ideal solution for monitoring and validating ISO cleanrooms (class 5-9).

With the optional temperature and humidity probe (see accessories), two additional air parameters can be measured. 
- Detects particle sources
- Evaluates indoor air quality
- Measures 6 different particle sizes (see specifications for details)
- Offers a flow rate of 2.83 l/min (0.1 cfm)
- Features a large, easy-to-read LCD screen
- Includes software
- Designed in accordance to ISO 14644-1 and EU GMP guidelines (compatible to JIS B9921
- Provides a concentration limit up to 4,000,000 cnt/ft³ at 5% loss of coincidence
- Stores up to 10,000 measurement values to internal memory
- Optional temperature and humidity measuring probe available (see accessories)
