DS4000 Display

A sophisticated single-channel, panel mount display, expertly engineered to integrate seamlessly with the Alpha Moisture Systems Dewpoint Sensor.

The Model 6020, combined with the Dewpoint Sensor, forms a high-precision dewpoint hygrometer system, ideal for accurately measuring trace moisture in process gases and dry compressed air. This system ensures long-term stability, rapid response and high sensitivity with an accuracy of ±2 °C (±3.6 °F) dewpoint.

Designed for operator convenience, the Model 6020 features our unique automatic calibration (AutoCal) and three hotkey functions accessible from the front panel, allowing easy setup of alarm trip points, unit selection and access restrictions. RS485 connectivity means users can easily configure the device for integration with PC systems, providing digital output for remote data interrogation. Each system is factory-calibrated and supplied with a calibration certificate traceable to National & International Humidity Standards at the National Physical Laboratory (NPL).

A fully self-contained, portable hygrometer designed to deliver precise trace moisture measurements of gases and dry compressed air for both industrial and laboratory applications.

With an accuracy of ±2 °C dewpoint and an overall range offered between -110 °C to +20 °C dewpoint, the Model DSP-FCI ensures reliable performance. The advanced dewSMART transmitter, utilizing ultra-high capacitance aluminum oxide sensing technology, guarantees unsurpassed repeatability and measurement precision — and is fully interchangeable without returning to Alpha Moisture Systems for calibration and setup. The hygrometer’s unique desiccant dry-down technology provides rapid response times, making it ready for spot-check readings with minimal air or gas usage. An integral sample flow control valve conditions high-pressure samples before introduction to the desiccant head assembly, and a built-in flow indicator with sample-specific gradation provides flow control.

Designed for ease of use, the DSP-FCI features a user-friendly interface and requires little to no maintenance. The digital screen offers versatile display options, allowing users to select from various moisture units, including °C, °F, ppb(v), ppm(v), ppm(w), g/m³, and lb/MMSCF. Additionally, the device includes a user-programmable parts per million (weight) function for specific gases, with pre-programmed settings for common gases like Air, Ar, H₂, SF₆, CO₂, and N₂.
