Unmatched precision and flexibility

The BT-620 is engineered for precision. With a flow rate of 1.0 CFM (28.3 LPM), maintained by volumetric flow control, this particle counter ensures accurate and consistent measurements across its six selectable size channels, ranging from 0.3 to 10 microns. Each channel can be individually set by the operator without the need for custom calibration, offering unparalleled flexibility in monitoring particulate matter.

The device’s large, easy-to-read display and integrated printer work together to verify particulate levels instantly. If the particle count exceeds the user’s pre-set limit, an audible alarm will sound, and the screen display, sample history, and printout will clearly indicate an alarm event. This immediate feedback is crucial for maintaining cleanroom standards and ensuring the safety of the environment.

Ideal for cleanroom compliance

In cleanroom environments, maintaining strict air quality standards is non-negotiable. The BT-620 is specifically designed to make compliance easy. It is fully compliant with 21 CFR Part 11, ensuring that data integrity is maintained at all times. The device includes a password protection feature to prevent unauthorized changes to user settings, adding an extra layer of security.

Moreover, the BT-620 meets the requirements of ISO 14644-1 and ISO 21501-4 with upgraded calibration. These international standards are critical for cleanroom environments, where even the smallest deviations in air quality can have significant consequences. The BT-620 provides the accuracy and reliability needed to meet these stringent standards consistently.

User-friendly design and operation

Despite its advanced capabilities, the BT-620 is incredibly user-friendly. The device features an intuitive, menu-driven interface that allows for easy navigation and setup. Operators can quickly adjust sample times, assign location IDs, and select size channels, making it simple to customize the device for specific monitoring needs.

The BT-620 also offers a generous data storage capacity, capable of storing over 8,000 sample events. This data can be easily viewed on-screen, printed, or downloaded to a computer using Met One’s ParticleView or Comet software, or simple ASCII terminal commands. For those needing real-time monitoring, the BT-620 offers an optional software upgrade to ParticleView RT.

Seamless integration with facility systems

The BT-620 is designed to integrate seamlessly with existing building automation systems and facility software. The device supports multiple connectivity options, including digital interfaces (Ethernet, USB, RS-232, RS-485) and analog output (0-5 VDC). This flexibility ensures that the BT-620 can easily be incorporated into MODBUS multi-drop networks and other facility management systems.

Additionally, the BT-620 includes a memory stick port for easy data transfer and backup. Whether you need to print sample data on-site or export it for further analysis, the BT-620 makes it simple and convenient.

Built-In printer for immediate data verification

One of the standout features of the BT-620 is its integrated printer, which plays a crucial role in maintaining data integrity. The printer offers two modes of operation:

Print Sample: This mode prints sample data at the end of each sampling event, including alarm notifications, date, time, and location information.
Recall Data: This mode allows users to print all sample data between two selected dates and times, providing a comprehensive record of air quality over a specified period.

This built-in printer ensures that critical data is always at your fingertips, whether you need immediate verification or a detailed report for compliance purposes.

Enhanced accuracy with volumetric flow control

Accuracy is at the core of the BT-620’s design. The device features volumetric flow control, which maintains a consistent flow rate of 1.0 CFM (28.3 LPM). This control is essential for ensuring that particle counts are accurate and repeatable, particularly in environments where precision is paramount.

The BT-620 also offers selectable count units, allowing users to display data in total count (TC), particles per liter (/L), particles per cubic foot (CF), or particles per cubic meter (M3). This flexibility ensures that the device can meet the specific needs of different applications and reporting requirements.

Portable and versatile

Despite being a benchtop unit, the BT-620 is highly portable, thanks to its compact design and stainless-steel housing. The device is both battery and AC-powered, offering up to 8 hours of operation on a single charge. This portability makes the BT-620 ideal for use in various settings, from cleanrooms to industrial facilities, and even remote locations where access to power may be limited.

Plug-and-Play Ambient Monitoring

For those needing additional environmental data, the BT-620 offers a plug-and-play option to immediately add ambient temperature and relative humidity capabilities to the displayed and logged data. This feature enhances the device’s versatility, making it a comprehensive solution for air quality monitoring.
