BT-610 Bench-Top Particle Counter
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.
Features
- Compact / Portable w/ built-in printer
- Volumetric Flow Control – improved accuracy
- Large Display – easily viewed from across room
- Improved Software
- 2-year Warranty
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. The user can select the sizes, each of the six channels may be individually set by the operator from 0.3 to 10 microns. 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 BT-610 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.
The BT-610 provides a full feature set in a lightweight convenient size. 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. A temperature / relative humidity plug-and-play option immediately adds ambient temperature and relative humidity capabilities to displayed and logged data.
