HK Instruments Siro-PM-rH-T-D Multifunctional indoor air quality transmitters for building automation systems (PM; rH; T)

Measurement ranges:

+ PM1/PM2.5/PM10:

0–50 μg/m³ / 0–500 μg/m³ (selectable via jumper)

IAQ index: 1-5 (WHO rating)

+ Temperature:  0...50 °C

+ Relative humidity: 0–100 %rH

Accuracy:

+ PM:

0…100 µg/m3:

PM2.5:  ±15 µg/m³ (at 25 ⁰C ±5 ⁰C)

PM1/PM10*:  ±25 µg/m³ (at 25 ⁰C ±5 ⁰C)

100…1000 µg/m3:

PM2.5:  ±15 % (at 25 ⁰C ±5 ⁰C)

PM1/PM10*: ±25 % (at 25 ⁰C ±5 ⁰C)

*PM1 and PM10 values are calculated from PM2.5 measurement reading with the default particle distribution
