Product details

The Model SDHmini portable hygrometer sets new industry standards for dewpoint measurement. With state of the art features and enhancements with support of USB and Bluetooth interfaces for communicating with PC and also support for thermal printer over Bluetooth.

A portable dewpoint hygrometer offering 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 the signal conditioning circuitry, memory management and a full colour graphics LCD. The on-board rechargeable lithium-ion battery, when fully charged, provides over 150 hours of logging capability and is fully recharged in 12 hours.

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. The inbuilt memory stores in excess of 300,000 readings including moisture and pressure compensated moisture readings with user selectable logging intervals from five seconds to one hour.

Key features of Model SDHmini and SDHmini-L

  • Automatic Calibration (AutoCal)
  • Desiccant dry down assembly for high speed measurements
  • User selectable engineering units – °C, °F, ppm(v), ppm(w), g/m³, lbs/MMscf
  • 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 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 (Portable printer available)
  • Robust and durable enclosure designed for use in the toughest environments
  • Truly portable and lightweight: less than 1.75 kg (3.8 lbs)
  • Calibration Certificate traceable to National & International Humidity Standards

The Desiccant Head Assembly

Keeping the sensor dry between tests ensures that the instrument is always ready to carry out rapid spot checks. The unique design of the desiccant head achieves this by surrounding the sensor with desiccant before the head is lifted for sampling.

At no time is the sensor allowed to come into contact with ambient air. The chamber is also designed so that the void space and chamber wall surfaces are purged with sample gas, prior to exposure of the sensor, giving faster, more accurate and reliable results.

Automatic Calibration

The most important and unique feature of the SHAW system is the automatic calibration facility. Each SHAW sensor is precisely manufactured to saturate with water vapour at its design maximum. Hence, when the sensor is exposed to moisture above its maximum operating range, it will rapidly come into equilibrium and cease to respond to any further increase in moisture. This forms the basis of automatic calibration.

The SHAW sensor can be checked by simply exposing it to any atmosphere which is wetter than the operating range of the sensor (usually room air is sufficient) by raising the desiccant chamber and performing the automatic calibration feature on the instrument. The sensor is now set up with the instrument and ready for use.

Automatic calibration can be carried out in-situ and without the need for any special equipment or skilled personnel. The net result is reduced downtime, minimal calibration costs and immediate verification of the system.
