Description

Model SDHmini-Ex hand held hygrometer sets new industry standards for portable dewpoint measurement equipment. Intrinsically safe and portable, this hygrometer offers quick and reliable spot check measurements of dewpoint and trace moisture content for industrial applications. Robust and lightweight, incorporating an intuitive menu structure and advanced digital features, enabling the user to perform moisture measurements in the toughest of environments, quicker and easier than ever before.

Certified intrinsically safe to ATEXIECEx and UL standards for use in hazardous areas. the SDHmini-Ex is the perfect hand held hygrometer for accurate and reliable measurements of dew point in compressed air and process gas, suitable for use in a wide range of industries, including power generation, semi conductor manufacture and pharmaceuticals.

The robust housing contains the SHAW moisture sensordesiccant dry-down chamber assembly and gas sample ports. Also incorporating advanced  signal conditioning circuitry, memory management and a full colour graphics LCD display. An onboard rechargeable lithium-ion battery provides over 150 hours of continuous operation on a full charge and the hygrometer is charged via USB or plug type to suit your geographical location. The intuitive menu system is simple to operate and can be viewed in the following ten language options: English, German, French, Spanish, Portuguese, Russian, Italian, Chinese, Japanese and Korean.

This dewpoint hygrometer includes real time data logging with download to PC capability and up to 300,000 readings can be captured and displayed via USB. Incorporating Bluetooth interfaces for PC communication and printing with a compatible Bluetooth printer also available. Its powerful microelectronics, selectable engineering units, intuitive menu structure and incorporation of the SHAW AutoCal function, allows the operator to achieve a meaningful reading in 5 – 10 minutes.
