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.
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 user’s 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.
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 operations 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 temperature and relative humidity capabilities to displayed and logged data.
