Met One 237 A/B Portable Air Particle Counters


This product is now obsolete.

MET ONE 237A and MET ONE 237B portable air particle counters are rugged, simple to use and light. With an inbuilt battery and integral printer the MET ONE 237 Series is ideal for monitoring large cleanrooms in addition to more demanding controlled environments such as LAF workstations, hospital pharmacies, and aerospace applications.

Met One offers battery-operated portability, up to six size channels and a built-in printerall in one simple, compact instrument. The Met One 237 counts airborne particles in up to six different size ranges simultaneously. Count data is displayed on the front-panel as total number of particles (cumulative count) or the particles in each size range (differential count).

The bright LED display lets you see the data easily and the printout shows cumulative and differential count data for each size range.

The Met One 237 offers four modes to provide quick answers to measurement questions and allow unattended operation:

  Manual mode: Completes one count cycle then turns the air pump off to prolong battery life.

  Auto mode: Repeats the count cycle for the number of cycles programmed to allow unattended monitoring.

  Concentration mode: Estimates the particle concentration within seconds.

  Beep mode: Provides one beep after the count exceeds a selected limit, which is useful for isolating sources of particle contamination such as leaks in filter banks.

It is easy to carry the Met One 237 counter right to the point of interest and obtain quick, accurate results that you can immediately print or download using PortAll™ Version 2 Software. Additionally, particle count data can be organized, archived and graphically trended. This easy-touse software can also be used to schedule the collection of samples by the air particle counter. A battery charge life of up to 8 hours ensures true portability and sample collection flexibility.
