Remote Dust Monitor ES-642

Features:
  • For dependable, ongoing outdoor operation, a tough weatherproof enclosure.
  • Maintains optical components clean so that the ES-642 may function in challenging conditions without performance deterioration.
  • Automatic Zero Calibration: By automatically changing the zero value every hour, this technique reduces long-term measurement drift.
  • Active intake humidity management with a controlled inlet heater helps to minimise measurement mistakes.
  • Information on particle content, flow rate, and instrument condition are shown on the front panel LCD.
  • Flexible mounting hardware is available, including mounting brackets for walls, 2″ vertical masts, and vertical masts up to 4.7 inches in diameter (120 mm).
