SDHmini-Ex Portable Hygrometer Shaw Moisture Meters SDHmini-Ex, hand held hygrometer, certified intrinsically safe and incorporating data logging, USB and Bluetooth interfaces for communication and printing, setting new industry standards for dewpoint measurement. An intrinsically safe, portable dewpoint meter offering quick and reliable spot-check measurements of dewpoint and trace moisture content for industrial applications. This robust and lightweight dewpoint instrument features an intuitive menu structure and advanced features which enable the user to perform measurements in the toughest of environments, quicker and easier than ever before. Perfect for industrial applications such as power utilities, natural gas exploration and production, air treatment plants, processing of chemical and pharmaceutical products, general engineering and more. Certified intrinsically safe to ATEX, IECEx and UL standards, SDHmini-Ex is the perfect dewpoint meter for reliable measurements of trace moisture in hazardous areas. Utilizing three features unique to Shaw Moisture Meters dewpoint instruments: AutoCal, the unique SHAW moisture sensor and the desiccant dry down chamber assembly. These features work together to ensure the sensor stays dry between tests and allows users to calibrate their hygrometer in situ without the need for any special equipment or training. The SDHmini-Ex is ideal for carrying out rapid spot checks. The robust housing also incorporates the signal conditioning circuitry, memory management and a full colour graphics LCD. The on-board rechargeable lithium-ion battery provides over 150 hours of continuous operation. The unit 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. Review logged data on the instrument or transfer via USB or Bluetooth interface for PC communication and printing. 0598 Certified intrinsically safe to ATEX, IECEx and UL standards for use in hazardous areas AutoCal (automatic calibration) Desiccant dry down assembly for high-speed measurements User selectable engineering units - °C, °F, ppm(V), ppm(w), g/m3, lb/MMSCF Accuracy of ±2 °C (±3.6 °F) Various measurement ranges available from -100 °C to +20 °C (-148 °F to +68 °F) dewpoint Full colour graphics LCD display with secondary display Advanced data logging and download to PC Rechargeable battery - over 150 hours of continuous operation on full charge USB charging and connection to PC interface Bluetooth connection and printing Robust and durable enclosure Truly portable and lightweight: less than 1.75 kg (3.8 lbs) Certificate of Calibration traceable to National & Internat

Desiccant Dry-Down Technology The desiccant and sensor are always isolated from atmospheric air to ensure an accurate reading. Sensor exposed to gas sample. Sample exhaust Sample gas inlet pipe Sensor Dry-Down Position 215 mm with head retracted 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.
