Dew point is defined as the lower temperature to which air must be cooled in order for condensation to occur. The dew point is dependent on the concentration of water vapor present, and therefore on the relative humidity.
Mini Hygrometer
The new Mini SADP is a state of the art portable dewpoint analyzer. The unit is self-contained incorporating the moisture sensor, dry-down chamber, electronics, display and rechargeable battery all in a corrosion and impact resistant plastic casing. The padded carrying case, makes it ideal for heavy use in demanding industrial environments


Dry Down Chamber
The sensor must always be drier than the sample to be measured. This is achieved with the use of dessicant chamber that can be raised and lowered over the sensor. In the head down position the sensor is surrounded by desiccant at all times whenever a measurment is not in progress and whenever the instrument is not in use. The sensor is only exposed to the sample gas during a measurement (the head raised position) and is never in contact with ambient air.
    The chamber is also designed so that the void space and chamber wall surfaces are purged with sample gas, before exposure of the sensor, so giving even faster, more accurate and reliable results.
