SDHmini Portable Hygrometer The SDHmini portable hygrometer sets new industry standards for dewpoint measurement. A portable dewpoint hygrometer which offers quick and reliable spot-check measurements of dewpoint and trace moisture content for industrial applications. This robust and lightweight instrument features an intuitive menu structure and advanced features which will enable the user to perform measurements in the toughest of environments, quicker and easier than ever before. The robust housing not only contains the moisture sensor, desiccant chamber and gas sample ports but also incorporates: signal conditioning circuitry, memory management and a full colour graphics LCD. The on-board rechargeable lithiumion battery, when fully charged, provides over 150 hours of continuous operation. The instrument operates with the following ten language options: English, German, French, Spanish, Portuguese, Russian, Italian, Chinese, Japanese and Korean. Powerful microelectronics provide automatic calibration with real time data logging graphical formats for the capture and display of up to 300,000 data points with USB and Bluetooth interfaces for PC communication and printing. AutoCal (automatic calibration) User selectable engineering units - °C, °F, ppm(V), ppm(w), g/m3, lb/MMSCF Desiccant dry down assembly for high speed measurements Accuracy of ±2 °C (±3.6 °F) Full colour graphics LCD display, with secondary display 10 language options Various measurement ranges available from -100 °C to +20 °C (-148 °F to 68 °F) dewpoint Rechargeable battery - over 150 hours of continuous operation on full charge Advanced data logging and download to PC USB charging/connection to PC interface Bluetooth connection/printing (SDHmini-L) Robust and durable enclosure, designed for use in the toughest environments Truly portable and lightweight: less than 1.75 kg (3.8 lbs) Certificate of Calibration traceable to National & Internatio

Desiccant Dry-Down Technology Sensor exposed to gas sample. Sample exhaust Sample gas inlet pipe Sensor Dry-Down Position 215 mm with head retracted The desiccant and sensor are always isolated from atmospheric air to ensure an accurate reading. Sensor surrounded by desiccant ensuring it is dry, ready for the next measurement. 259 mm with head extended The unique design allows purging of the gas in the “Dry-Down Position” which will bring all surfaces and voids to equilibrium. General Assembly Diagram Read Position Keeping the sensor dry between tests ensures that the SDHmini is ready to carry...
