  • Flow Rate: Nominal sample flow rate of 75 mL/min ±10%.
  • Efficiency: 100% counting efficiency of the sampled volume.
  • Zero-Count Level: Maximum of 50 counts per liter.
  • Pressure: Operates with a maximum system pressure of up to 100 psi.
  • Temperature Ranges: Sample 15–50 °C; Operating environment 18–29 °C.
  • Connectivity: Ethernet communication and 4–20 mA analog outputs (five total: four particle channels, one instrument status).
  • Power: 100–240 V AC at 50–60 Hz.
  • Lead Time: 60 days or less after ARO.
  • Vendor Qualifications: Must provide local support and have conducted UPW business for more than 5 years.
