CPM 700 (Continuous Particulate Monitoring)

Additional Details

Description for CPM 700:

          Continuous particulate monitoring 700 series monitors are advanced detection devices that measure changes in particulate concentration. Using a unique emissions detection technique, CPM 700 series instruments maintain calibration because they are less affected by dirty or misaligned optics, or a faulty light source often found in other type detectors. Bha offers two models in this product series: the standard CPM700, and the more advanced cpm 750.

Features and benefits of CPM 700:

1. Emissions detection technique - self-compensating, no drift, low maintenance .
2. Span/zero check with automatic check cycle.
3. Three stage alarm systems.
4. Ambient light detection - automatically detects and offsets for ambient light.
5. Adjustable damping - smoothes the response to rapid fluctuations in emissions.
6. Led bar graph display.
7. Additional feature on the cpm 750 model
Analog output- allows the connection of external equipment.
