BT-637 Bench-Top Particle Counter

The Portable Solution—Monitor Your Environment or Verify Your Processes

Affordable Bench Top with High End Performance
The BT-637 is a full featured unit suitable for continuous monitoring at a 0.1cfm flow rate. This unit has volumetric flow controlled with internal temperature sensors that will continually monitor and correct the flow. An audible alarm alerts the user when the flow rate varies more than ±5%.

The battery or AC operated portable laser particle counter provides 8 hours operating time and a less than 3 hours recharge time. This is a real-time particle counter capable of logging up to 8000 records.

The Bench-Top unit has six pre-set particle channels (0.3, 0.5, 0.7, 1.0, 2.0, & 5.0) and is user customizable so two “favorite” sizes can be readily displayed to avoid screen scrolling. A large easy to read back lit LCD, combined with a loud programmable audible alarm make this a great fit for all applications.

User Friendly – Out of the Box Operation
A simple user interface and operation manual gets you up and running quickly making the training of your team a breeze.

Flexible Data Interface
Your communication needs are addressed. The unit comes standard with RS-232, RS-485, Analog (0-5V), USB interface, and a Memory Stick port. The BT-637 comes standard with user friendly computer software.
