Hach Met One 3415 Airborne Particle Counter

The Hach Met One 3415 is a portable airborne particle counter (PN 2088900-02). It is part of the reliable Met One 3400 Series. Specifically, engineers designed it for cleanroom verification and routine environmental monitoring. Regulated contamination-control facilities rely on this unit. Consequently, it combines high-sensitivity detection with automated compliance reporting.

Hach Met One 3415 Measurement Capabilities

The instrument operates at a calibrated sample flow rate of 1.0 CFM (28.3 L/min). Furthermore, it detects airborne particulates down to 0.3 µm. Key operational specifications include:

• Particle Sizing Channels: It measures six configurable size channels simultaneously. These channels include 0.3 µm, 0.5 µm, 1.0 µm, 3.0 µm, 5.0 µm, and 10.0 µm.
• Automated Compliance Wizard: The software includes pre-set routines for ISO 14644-1, EU GMP Annex 1, and FS 209E standards. Therefore, operators can complete certifications without manual pass/fail calculations.
• Laser Diode Reliability: It uses a long-life diode laser with continuous diagnostic tracking. As a result, it prevents false counts and maintains stable measurements across long sampling cycles.

Hach Met One 3415 Hardware and Interface

The counter features a rugged stainless steel enclosure. This housing resists chemicals and tolerates routine wipe-down protocols.

Primary hardware components include:

• Color Touchscreen Display: A bright graphical screen displays live differential and cumulative particle counts. In addition, technicians can easily monitor sample progress.
• Integrated Thermal Printer: An onboard printer generates immediate hard-copy test records. Thus, users get instant certification summaries directly at the sampling location.
• Dual-Battery Operation: Hot-swappable battery bays enable continuous field operation. Consequently, audits proceed without downtime between test rooms.

Data Management and Cleanroom Uses

The unit supports data integrity protocols aligned with 21 CFR Part 11 requirements. Specifically, it offers multi-level user passwords, audit trail logging, and secure onboard records. In addition, operators can export data via USB drives, Ethernet, or RS-485 connections.

Ultimately, the Hach Met One 3415 supports routine environmental audits in pharmaceutical production, semiconductor fabs, medical packaging, and sterile compounding suites.
