Measured quantities and conditions of use
- The combined probe measures temperature and relative humidity. In addition to direct readings, derived parameters are available, such as dew point, absolute humidity, mixing ratio and enthalpy.
- The scope of supply includes a combined probe with a 2 m cable. W&T permits the probe connection to be extended to a maximum of 20 m for this model.
- Values are updated every 4 seconds. The history is stored at separate intervals: 15 or 30 seconds, or 1, 5, 15 or 60 minutes.
- Up to 12 configurable alerts enable notifications via email or SNMP. The network module and probe have their own operating conditions; the probe’s measurement range is not the same as the module’s operating temperature.
- A humidity measurement range of 0–100 % RH does not imply that condensation on the electronics is permitted. Permissible operating conditions are specified separately in the technical table.
Commissioning and accessories
Position the probe so that it measures the required area and is not affected by heat from surrounding equipment. Set the IP address, the displayed parameters, the logging interval and the alarm limits. If extending the cable, use suitable cabling and do not exceed a length of 20 m.

Frequently Asked Questions
Can I extend the probe cable?
Yes. This model comes with a 2-metre cable, which can be extended to a maximum of 20 metres. Use cabling that complies with the manufacturer’s wiring specifications.
Does the temperature measurement range also apply to the network module?
No. The measurement range applies to the probe. The module itself has its own specified operating temperature and installation conditions.
What does the stated typical accuracy mean?
Applies under the conditions specified for the particular quantity and range in the table. When assessing these, it is necessary to distinguish between temperature, relative humidity and, where applicable, pressure, as well as long-term stability.
