HK Instruments Siro-MOD-PM-A-D Indoor Air Quality Transmitter (PM: 0–500 μg/m³)

Measurement ranges:

+ PM1/PM2.5/PM10: 0–50 μg/m³ / 0–500 μg/m³ (selectable via jumper); IAQ index: 1-5 (WHO rating)

Communication: RS-485 Modbus (RTU)

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.
