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).
