The portable COSA Xentaur XPDM dew point meter is a battery-operated, hand-held dew point transmitter, designed for applications where quick and accurate dew point measurements have to be made. The COSA Xentaur XPDM dew point meter quickly and easily provides accurate spot-checks of moisture in gases over the range of -148°F to +68°F (-100°C to +20°C) dew point.

The COSA Xentaur XPDM dew point meter features Xentaur HTF™ aluminum oxide sensors. Due to a hyper-thin film and a special activation process, these sensors offer significant performance advantages over all other aluminum oxide moisture sensors including better sensitivity, better repeatability, and faster response times. Also, the measurement system is less prone to noise and drift, and signal conditioning is kept to a minimum. Xentaur sensors are interchangeable, waterproof, and can be field calibrated anytime without the need for expensive and cumbersome calibration standards.

In addition to specialized sensors, the COSA Xentaur XPDM dew point meter also features a simple, menu driven user interface with a digital LCD display and 4 push buttons; user selectable engineering units; and a pressure correct function.

The COSA Xentaur XPDM dew point meter is powered by a 9V battery which lasts for up to 100 hours of continuous operation. An automatic shutoff feature makes sure that the battery is not kept in use unnecessarily. The COSA Xentaur XPDM dew point meter can also be equipped with an external power supply jack and signal output board. The COSA Xentaur XPDM dew point meter can then operate from 15 - 20 V AC/DC, or from a car battery adapter. All signal outputs are isolated from the sensor. The analog output can be current or voltage. The RS-232 output can be easily connected to a PC or a modem.
