An inspection device according to an embodiment can conduct high temperature inspection and low temperature inspection on an object to be inspected. The inspection device includes an inspection chamber in which inspection is conducted on the object; a dry air supply section that is connected to the inspection chamber via a first valve and that is configured to supply dry air into the inspection chamber; a dew point meter that is connected to the inspection chamber via a second valve and that is configured to measure a dew point in the inspection chamber; and a bypass pipe connecting the dry air supply section and the dew point meter via a third valve.

Apparatuses, systems, and methods for monitoring the curing of concrete employ a vacuum to draw a moisture sample from concrete (e.g., curing concrete, etc.) into the presence of a single dew point temperature (DPT) sensor. Moisture samples may be selectively drawn into the presence of the DPT sensor from sampling chambers within the concrete at a variety of locations across the concrete and/or from a variety of depths within the concrete. The dew point temperature data may be used to determine the quality of a concrete curing process.

A dew point sensor arrangement includes sensing and dry gas source conduits coupled to a dew point sensor. A sensing valve with a sensing valve member couples the sensing conduit to the dew point sensor. A drying valve with a drying valve member couples the dry gas source conduit to the dew point sensor. The sensing valve member fluidly separates the sensing conduit from the dew point sensor in a sensing valve member closed position, the drying valve fluidly couples the dry gas source conduit to the dew point sensor in a drying valve member open position, and the drying valve member moves to the drying valve member open position when the sensing valve member moves to the sensing valve member closed position to dry the dew point sensor using dry gas provided through the dry gas source conduit. Semiconductor processing systems and dew point sensing methods are also described.
