The Model SDHmini portable hygrometer sets new industry standards for dewpoint measurement.
A portable dewpoint hygrometer which offers quick and reliable spotcheck 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 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.
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 continuous operation.
