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
Communication: RS-485 Modbus (RTU)
Accuracy:
+ Relative humidity: ±2.2 % rH (typical at 20 °C, 30 % rH)
+ Temperature: ±0.4 °C (typical at 20 °C)
+ 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)
