Met One Instruments – Six Channel Bench Top Particle Counter – BT-620

This benchtop particle counter has a large, easy-to-read display, audible alarms, and an 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.

Ideal for use in cleanrooms, the BT-620 was designed to easily integrate with existing building automation systems, facility software, processors, or may be used as a standalone unit.

Key Features

• 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 temperature and relative humidity capabilities to displayed and logged data.
