BT-620 Bench-Top Particle Counter美國Met One Instruments BT-620激光粒子計數器性能特點
The BT-610 is a compact battery operated particle counter with six selectable size channels, built-in printer, housed in a portable stainless steel case. Flow rate is 0.1 cfm (2.83 lpm) and is maintained with volumetric flow control for improved accuracy.

Simple Operation
  The BT-610 has a large size display with very large characters, audio  alarm, and internal printer that work together to verify particulate  levels. If the particle count exceeds a pre-set limit, the audible alarm  will beep, the screen display will flash, and the printer will print the  alarm value. Two programmable count alarm limits may be set.

User Selectable Sizes
  Each of the six channels may be individually set by the operator  from 0.3 to 10 microns. Custom calibrations are not required.

Data Storage and Connectivity
  The BT-610 stores over 8,000 sample events. Sample history events  can be viewed or printed and downloaded to a computer using  Comet software or simple ASCII terminal commands. Connectivity   is built-in for both digital  (RS-232, RS-485) and analog output (0-5 VDC). The BT-610 also includes USB interface, and a Memory 
  Stick port.

Printer
  The Printer has two modes of operation.
  Print Sample: prints sample data at the end of each sample  including alarm, date, time and location.
  Recall Data:  prints all sample data from first selected date and time to second selected date and time.

Portable Desk Top 
  The BT-610 provides 6 channels, built-in printer and battery operation in a compact stainless steel case. The built-in battery provides  24 hours of typical (intermittent) operation and 8 hours continuous  operation. Connect the AC adapter/charger for longer operation  and battery charging.

Temperature / Relative Humidity Option
  A plug-and-play option can immediay add ambient temperature and relative humidity capabilities to displayed and logged data .
