Bench-Top Particle Counter BT-610 Introduction：

user's manual data sheet

The BT-610 is a compact battery-operated particle counter with six selectable size channels and built-in printer all 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.

OPERATIONS / INTERFACE：

Met One’s BT-610 has a large display with very large characters, audio alarm, and internal printer that work together to determine and record 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. The user can select the sizes and individually set each of the six channels from 0.3 to 2.0 microns in .1 micron increments and from 2.0 to 10 microns in 0.5 micron increments. Custom calibrations are not required.

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. The 610 printer has two modes of operation; Print Sample and Recall Data. A password feature prevents unauthorized changes for 21 CFR Part 11 compliance. A built-in battery provides 24 hours of typical (intermittent) operation and 8 hours of continuous operation with 5-minute printing. For longer operation time and battery charging the unit may be plugged into an outlet. An optional temperature / relative humidity sensor plug-and-play option immediately adds ambient temperature and relative humidity capabilities to displayed and logged data.
