DSP-Ex | Portable Dewpoint Hygrometer
A self-contained, portable hygrometer designed to deliver precise trace moisture measurements of gases and dry compressed air, certified intrinsically safe for hazardous applications.
Certified intrinsically safe to ATEX standards (ATEX Ex ia IIC T3/T4 Ga) and CE approved, the Model DSP-Ex is suitable for use in hazardous areas. With an accuracy of ±2 °C dewpoint and an overall range of -110 °C to +20 °C dewpoint, the DSP-Ex ensures reliable performance. 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. The advanced dewSMART transmitter, utilising 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 DSP-Ex 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.

BTP01 | Bluetooth Printer
A portable printing solution, ideally suited for the demanding conditions of fieldwork. The lightweight printer connects via Bluetooth to our SADPmini2-L and SADPmini2-Ex dewpoint meters, rapidly printing live data, stored readings, or screenshot graphs.
Engineered for portability, the BTP01 Printer comes equipped with a protective carry case featuring a belt loop for enhanced device security. The transparent window on the case allows easy access to function buttons without removing the printer, minimising the risk of damage.
It features a direct thermal printing method for high-quality, maintenance-free outputs, along with easy paper roll replacement, ensuring minimal downtime and maximum efficiency.
DIS030 Dewpoint Display
A compact, self-contained, single-channel, 4-digit LED display designed for seamless integration with the range of PDT dewpoint transmitters. Weighing only 125 g, this lightweight display is perfect for direct installation on the transmitter using the secure M12 connector.
The DIS030 display offers ease of use and installation, providing a straightforward solution when local indication is required. With its adjustable design, the display can rotate 270 degrees for better positioning, while the display fascia rotates 360 degrees to accommodate the placement of your dewpoint transmitter. The DIS030 can be user-configured, when ordered, to view readings in °C dewpoint, °F dewpoint, ppm(V) or ppb(V) according to your preferences.
Powered by a 4-20 mA loop, the DIS030 is suitable for continuous measurement when paired with our PDT Dewpoint Transmitter. This plug-in display requires little to no maintenance, ensuring hassle-free operation. For applications demanding additional functionality, consider our DS1200 display for most routine applications or the DS4000 display for more advanced applications requiring a user-configurable display and greater versatility.
SS-1 & SS-2 Sample Systems
Precision-engineered sample systems for continuous trace moisture measurement of process gas and dry compressed air, designed specifically for low-pressure systems.
The SS-1 operates with the sensor at atmospheric pressure, while the SS-2 operates at system pressure, both accommodating a maximum inlet pressure of 50 barg (725 psi). They include comprehensive pressure and flow control, sample filtration to remove particulates, an auxiliary inlet for a second sample or calibration gas, and an outlet for sample recovery or disposal.
Manufactured for durability and reliability, these systems offer a compact, easy-to-install design that comes fully assembled. Their modular build is ideal for panel, surface, or weatherproof mounting, and features high-quality stainless steel pipework and fittings, with all major components clearly labelled and a flow schematic displayed on the aluminium front panel.
