Met One BT-620 Bench-Top Particle Counter

Met One BT-620 Bench-Top Particle Counter

Our BT-620 Bench-Top Particle Counter provides a full feature set in a lightweight convenient size.
This Counter monitors 6 particle sizes, includes a built-in printer, is battery or AC operated in a
stainless-steel case. The BT- 620 flow rate is 1.0 cfm (28.3 LPM) and is maintained with volumetric
flow control for improved accuracy. Like the 610, the 620 data is easily viewed on its display from
distances exceeding 3 meters.

Operation

Our BT-620 Bench-Top Particle Counter provides a full feature set in a lightweight convenient size: 6
particle sizes, built-in printer, battery operation and a 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. A temperature / relative humidity
plug-and- play sensor option immediately adds ambient temperature and relative humidity
information to the displayed and logger data.

The BT-620 has a large, easy to read display, audible alarm and internal printer that work together to
verify particulate levels. If the particle count exceeds the user’s re-set limit, an audible alarm will
sound. The screen display, sample history and printout will indicate the alarm event. Two
programmable count alarm limits may be set. The user can select the particle sizes for each of the six
channels from 0.3 to 10 microns. Custom calibrations are not required.

This Bench-Top Particle Counter stores over 8,000 sample events. Sample history can be viewed,
printed or 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 analogue (0-5
VDC). The BT-620 also includes a Memory Stick port. The built-in printer has two modes of
operation. Print Sample: prints the sampled data at the end of each sample including alarm, date,
time and location. Recall Data: prints all sampled data from the first selected date and time to the
second selected date and time.
