![Shaw SDHmini-EX [SDHmini-EX-B-4-EU] Intrinsically Safe Dewpoint Hygrometer, Blue and 1/4 in Swagelok SS Compression Type](image/cache/wp/gj/Products/Shaw_SDHmini-EX-800x800.webp "Shaw SDHmini-EX [SDHmini-EX-B-4-EU] Intrinsically Safe Dewpoint Hygrometer, Blue and 1/4 in Swagelok SS Compression Type")
An intrinsically safe 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.
Certified intrinsically safe to ATEX, IECEx and UL standards, the SDHmini-Ex is the perfect tool for reliable measurements in hazardous areas.
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 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 with USB and Bluetooth interfaces for PC communication and printing.
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.
