SPM Dust Analyser

More About SPM Dust Analyser -

• Product Description -

  • Wide Measurement Range: Monitors particulate concentrations from 0 to 1000 mg/m³ with selectable range.
  • Dynamic Detection Principle (DDP): Ensures superior stability and minimal drift over time, even with dirty optics.
  • Robust Construction: 316L stainless steel Transceiver and Reflector heads with air-purge assemblies.
  • Dual Operation Modes: Available as a standalone unit or with an optional Operator Interface (OI) for centralized control.
  • Real-Time Readings: Outputs in mg/m³, calibrated against standard reference measurements.
  • Simple Maintenance: Easy access to optical components for routine cleaning; no moving parts.
  • Integrated Calibration Check: Electronic calibration verification without disrupting operations.
  • Flexible Installation: Choice of wall-mounted or panel-mounted OI, or direct USB/Modbus communication via TRX head.
  • PC Software Included: Intuitive utility software enables setup, control, and data logging from any PC or laptop.
