SADPmini2-Ex Portable Dewpoint Hygrometer
Certified intrinsically safe to IECEx, ATEX, and cULus standards, our SADPmini2-Ex portable dewpoint hygrometer combines safety and performance — suitable for use in hazardous areas.
The SADPmini2-Ex advanced portable hygrometer is ideal for precise trace moisture measurement in hazardous environments and with potentially explosive gases — with logging capability and Bluetooth connectivity to our portable printer. The full-colour LCD shows multiple engineering units simultaneously, along with real-time graphing and screenshot features.
Market leading sensing technology combined with a unique desiccant head assembly ensures unparalleled speed of response and trace moisture detection. As a result, the SADPmini2-Ex offers exceptional sensitivity — accurate to ±2 °C (±3.6 °F) dewpoint — and fast, consistent operation with minimal air/gas usage.

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.
PDT Dewpoint Transmitter
A highly efficient and economical solution designed for trace moisture measurement in gases and dry compressed air, particularly suited for applications requiring monitoring of higher, ‘wetter’ dewpoints.
The PDT Dewpoint Transmitter offers a practical approach to continuous dewpoint measurement, catering for diverse requirements down to -60 °C dewpoint and available with three specific dewpoint ranges: -60 °C to +20 °C, -40 °C to +30 °C and -20 °C to +50 °C.
The compact 2-wire, 4-20 mA loop-powered transmitter features a bulk polymer sensing element — delivering excellent accuracy, stability and response speed across various dewpoint ranges. It is engineered to withstand pressures up to 5,000 kPa (50 barg), ensuring robust performance under demanding conditions. It offers IP65/NEMA 4 protection and for enhanced safety and reliability, the electrical connections are made via a durable M12 industrial connector.
PSS | Portable Sample System
Specifically designed to precondition pressurised gas samples for dewpoint measurement, our PSS is the ideal sample system for the SADPmini2, SADPmini2-L and SADPmini2-Ex Dewpoint Hygrometers.
The PSS ensures optimal sample conditioning for accurate dewpoint measurements and a versatile solution for trace moisture analysis in various applications, including hazardous areas.
Whether for intermittent use or spot checks, the PSS offers a reliable, lightweight solution for accurate dewpoint measurement in any field condition. The system comes equipped with an integrated pressure regulator and flow indicator, allowing for precise control over sample flow and pressure, and a padded carrying case, ensuring protection and ease of transport to any site.
