The Model 4650-PM is a forward-scatter optical monitor for measuring particulate matter in stacks and ducts where condensed water is not present. It features a 316 stainless steel probe with 550 mm insertion depth and DN80 PN10/16 or 3 in. 150 lb ANSI mounting. The system detects concentrations from 0.01 to 200 mg/m³ with a limit below 0.1 mg/m³ and supports flue gas temperatures up to 250°C standard or 500°C with the high-temperature option. The probe is sealed to IP66 and uses 30-40 liters/minute air purge. The control unit provides RS485 Modbus and 4-20 mA outputs, with automatic calibration and data logging. It complies with EPA PS-11, MATS, and Boiler MACT and can operate as a PM-CEMS or PM-CPMS. The measurement path has no moving parts except the calibration device.
4650-PM provides the stable, accurate low-range measurement of particulate matter in stacks and ducts where water droplets are not present in the flue gas. NOTE: The 4650-PM is currently available only in the USA and China.
