LANDTEK DP29-40 Portable Chilled Mirror Dew Point Instrument
LANDTEK DP29-40 Portable Chilled Mirror Dew Point Instrument
LANDTEK DP29-40
The LANDTEK DP29-40 is a multifunctional portable dew point instrument based on the chilled mirror measurement principle. It is intended for field and laboratory applications where accurate and stable determination of moisture in gas is required.
According to the datasheet, the DP29-40 is specifically designed for air dew point measurement. It is suitable for use as a reference instrument in electronic component durability testing, for dew point control in firing furnaces, and for dew point control in fuel cell test systems.
The instrument operates by cooling a mirror surface in a controlled manner until condensation begins to form. The temperature at that moment is used to determine the dew point.
The DP29-40 is designed to provide accurate and repeatable measurements, while the system offers stable operation without the need for frequent recalibration.
A built-in electronic sample gas flow monitor helps maintain stable measurement conditions during operation.
The model provides an RS-232 interface for connection to a PC, allowing measurement data to be transferred for further processing.
The LANDTEK DP29-40 is suitable for laboratory measurements, dry-air monitoring, furnace processes, test systems, and other applications requiring reliable air dew point measurement.
