BT-620
Bench-Top Particle Counter
The BT-620 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 1.0 cfm (28.3 lpm) and is maintained with volumetric
flow control for improved accuracy.
Simple Operation
The BT-620 has a large easy to read display, audio alarm, and
internal printer that work together to verify particulate levels.
If the particle count exceeds the users pre-set limit, the audible
alarm will sound and the screen display, sample history and
printout will indicate an alarm event. 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-620 stores over 8,000 sample events. Sample history events
can be viewed or printed and downloaded to a computer using
Particle View software or simple ASCII terminal commands.
Connectivity is built-in for both digital (Ethernet, USB, RS-232,
RS-485) and analog output (0-5 VDC). The BT-620 also includes
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-620 provides 6 particle sizes, built-in printer and battery
operation in a compact stainless steel case. The built-in battery
provides over 8 hours of typical (intermittent) operation or 4 hours
continuous operation. Connect the AC adapter/charger for longer
operation and battery charging.
Temperature / Relative Humidity Option
A plug-and-play option can immediately add ambient tempera-
ture and relative humidity capabilities to displayed and logged data
.
