Beta-ray Online Particulate Matter Monitor
Advanced beta-ray absorption technology for direct measurement of particulate matter mass concentration, unaffected by particle composition, density, or color variations.
Key Features
- Utilizes low-density, low-activity 14C source with 5700-year half-life for stable, safe measurement without special protection requirements
- Intuitive human-machine interface with 5-inch LCD display showing concentration data, historical records, calibration logs, and instrument status
- Local data storage capacity for over 3 years of records
- Comprehensive connectivity options including wireless, wired interfaces, digital I/O, 4-20mA, and RS485
- Proprietary patented paper transport mechanism with advanced algorithms to prevent paper breakage and jamming
- Extended maintenance intervals exceeding two months (excluding routine tape replacement)
- Annual calibration verification with calibration record query functionality
- Cloud platform and mobile APP integration with extensive software capabilities
