Specification
Accuracy: | CO: 43 ppm + 3 % of reading (typical), additional 60 ppm for first weeks Relative humidity: 2.4 % rH (typical at 20 C, 30 % rH) Temperature: 0.5 C (typical at 20 C) VOC*: 15 % of reading (typical) *VOC sensor is tuned for typical IAQ Mix of 22 VOCs as defined by Mlhave et al. (1997) PM: 0100 g/m3: PM2.5: 15 g/m3 (at 25 C 5 C) PM1/PM10*: 15 g/m3 (at 25 C 5 C) 1001000 g/m3: PM2.5: 15 % (at 25 C 5 C) PM1/PM10*: 15 % (at 25 C 5 C) *PM1 and PM10 values are calculated from PM2.5 measurement reading with the default particle distribution. |
