• Particle-Counting Data Goes to PC via Ethernet or USB Memory Stick
• No Device Drivers or Software Required
• User-Selectable Size Channels
• Easy-to-Read Display
• Alpha-Numeric Location Names & Alarms for User-Selected Particle Channels & Limits

The MET ONE HHPC 3+ (0.3 μm) is a lower-cost, three-channel instrument designed for contamination-sensitive industrial environments

Concentration limits:
4,000,000 / ft3 @ 10% coincidence loss HHPC 6+, HHPC 3+ (0.3μm);
2,000,000 / ft3 @ 10% coincidence loss HHPC 2+, HHPC 3+ (0.5μm)

Communication features include access to particle-counting data directly to PC via Ethernet or USB memory stick. No device drivers or software are required. Display configuration features include user-selectable size channels with optimized, large font. Display data modes feature traditional tabular particle counts or trend graphs for easy particle profiling. Security features include optional administrator password control and alpha-numeric location names and alarms for user-selected particle channels and limits. The easy-to-read, high-resolution display is fully configurable with on-the-spot process profiling to pinpoint particle events.

It's ideal for cleanroom optical component assembly where routine monitoring is conducted at 0.5 µm and 5 µm per ISO 14644, but 0.3 µm sensitivity is needed for HEPA filtered-workstation spot checks. The MET ONE HHPC 6+ is a fully-featured, six-channel particle counter designed for a wide range of tasks in high-technology cleanroom manufacturing environments such as semiconductor or flat panel display manufacturing. The unique cradle provides convenient PC access to particle-counting data via Ethernet or USB cable while it ensures the HHPC 6+ is charged and ready for use at all times. The MET ONE HHPC 3+ (0.5 μm) is a three-channel, 0.5 µm particle counter that can be configured to monitor 1.0 and 5.0 μm, which is useful when classifying to ISO 14644-1. The MET ONE HHPC 2+ is a two-channel, 0.5 µm particle counter designed as an affordable tool for the routine monitoring of controlled environments in accordance with ISO 14644 Cleanroom Classifications. Regulated and semi-regulated production environments that adhere to a GMP principle, such as aseptically packaged food and beverage filling lines, hospital labs, and formulating pharmacies, frequently choose the MET ONE HHPC 2+ and 3+.
