Dew point:
±1 °C Td (0 ... 20°C Td)
±2 °C Td (-70 ... 0 / +20 ... +50 °C Td)
±3 °C Td (-100 ... -70 °C Td)
Temperature: ± 0.3°C
Pressure: 0.5% FS
Ambient/process temperature 23 °C ± 3 °C
Ambient/process humidity <95% rH, no
condensation
Airflow > 2 l/min at sensor tip
In order to reach a fast response time please
ensure a flow rate of 2... 5 l/min at the
sensor tip.
Note:
If the Measuring chamber PTP-MK is used,
this flow rate will be maintained by the
chamber at a pressure > 0.3 MPa.
