Siemens QPM2102 is a duct-mounted CO2 and VOC sensor that measures CO2 by NDIR and reports VOC levels for duct air-quality monitoring. It provides selectable analog outputs (0-5 V, 0-10 V, or 4-20 mA), operates from 24 VAC or 15-35 VDC, and includes a tubular immersion length adjustable from 70 to 135 mm for duct installation. Typical applications include HVAC demand control ventilation and indoor air-quality monitoring.
NDIR CO2 measurement range 0 to 2000 ppm; VOC measurement up to 0 to 100%
Selectable outputs: 0-5 VDC, 0-10 VDC, or 4-20 mA; output switches to reflect higher measured value
Operates on 24 VAC or 15-35 VDC; immersion length 70-135 mm; terminal-strip electrical connection
Product Highlights
Duct-mounted CO2 and VOC sensor with NDIR CO2, selectable analog outputs, and adjustable immersion length.
