Model 6020 Display & Intrinsically Safe Sensor

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.

Featuring 3-stage chilled mirror technology and integral cooling, the CMH-RPC delivers precise and continuous moisture measurements up to -95 °C frost/dew point, translating to 37 ppb(V), making it an indispensable tool for high-accuracy applications.

The CMH-RPC offers unmatched accuracy for critical applications in laboratories and research facilities and as a reference standard for calibrating other moisture measurement instruments, delivered ready for immediate bench-top installation.

Our Model CMH Chilled Mirror Hygrometer accurately measures the dewpoint of a gas by cooling a mirrored surface, over which the gas flows until a layer of dew forms on the surface.

A sophisticated, panel mount, single-channel display, designed to enhance continuous trace moisture measurement in various gases and dry compressed air systems — when used with a compatible dewpoint transmitter.

The DS1500 incorporates RS485 and MODBUS (RTU) capabilities to facilitate remote interrogation and comprehensive communication with the AMT, AMT-Ex and PDT dewpoint transmitters, for continuous trace moisture measurement across a range of applications.

Factory configured to user specifications, the DS1500 can display measurements in °C dewpoint, °F dewpoint, ppm(V), ppb(V), g/m³, or lb/MMSCF on a large, six-digit, red LED display, providing clear and immediate data readouts. It offers Process Variable (PV) retransmission in 0-20 or 4-20 mA and is user-configurable to input pressure for pressure dewpoint conversion — offering a solution that is as versatile as it is reliable.
