The portable COSA Xentaur XPDM dewpoint meter is a battery-operated, hand-held dewpoint transmitter, designed for applications where quick and accurate dewpoint measurements have to be made. The COSA Xentaur XPDM dewpoint 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) dewpoint.

The COSA Xentaur XPDM dewpoint 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 dewpoint 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 dewpoint 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 dewpoint meter can also be equipped with an external jack and signal output board. The COSA Xentaur XPDM dewpoint 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.
