BT-610 Bench-Top Particle Counter

The BT-610 is a compact battery operated particle counter with six selectable size channels, built-in printer, 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
Six programmable particle size ranges. Operator can set sizes from 0.3 to 10 microns. No need for custom calibrations.

Data Storage and Connectivity
Store up to 8,000 sample events. Sample history events can be viewed or printed and download 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 Printer has two modes of operation. Print Sample: prints sample data 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
Convenient size and lightweight for portability with full feature set for desk top operation. Built-in Battery provides 24 hours of typical (intermittent) operation and 8 hours of continuous with 5 minute printing. For longer operation time and battery charging the unit may be plugged into a mains outlet.

Temperature / Relative Humidity Option
A plug-and-play option that immediately adds ambient temperature and relative humidity capabilities to displayed and logged data.
