Rotronic HL-20D 温湿度数据记录器 (0~100%RH; 0~50°C)

- Humidity measurement

Measurement method: ROTRONIC HYGROMER® IN-1

Measurement range: 0...100 %rh (non-condensing)

Accuracy at 23 °C: ±1.3 %rh @ 0…10 %rh

                               ±0.8 %rh @ 10…60 %rh

                               ±1.3 %rh @ 60…100 %rh

Repeatability: 0.3 %rh

Response time: Typical 3 min. (Depends on air flow)
