SVC HR-768i

High Resolution

Field Portable Spectroradiometer

Superior data quality provided by the SVC HR-768i coupled with the ability to collect and review data without an external computer make the SVC HR-768i one of the best instruments available for field applications. The internal CPU coordinates the spectral data collection as well as functions provided by the internal GPS, onboard digital camera and second Bluetooth radio for communication with external sensors. The SVC HR-768i is the basis of the multi-sensor data collection system.

The use of 100% linear array detectors ensures excellent wavelength stability, while the thermoelectrically cooled InGaAs and extended InGaAs detectors provide superior radiometric stability.

Fixed foreoptics and hard-mounted internal spectrometer elements combine to produce a robust and efficient optical path, ensuring reliable data under the most demanding field conditions. The internal CPU enables a full day's data to be acquired, displayed and recorded with no external computer. The SVC HR-768i firmware/software automatically record the longitude, latitude and time of day from the internal GPS receiver, and a digital photograph is stored as a separate linked file for each spectral measurement. This greatly eases record keeping in the field while providing positive, coded identification for subsequent data analysis.

The SVC HR-768i, weighing only 8.5 pounds, is the lightest and the most portable field spectroradiometer providing this full range of features.

The system is available with optional foreoptics and fiber optic bundles that are easily changed in the field. The spectroradiometer system is furnished in a durable, waterproof field case.

Rugged PDA

The SVC HR-768i is furnished with two versions of SVC's proprietary software. One operates with PCs and laptop computers running Windows Operating Systems. The second supports PDAs running operating systems including Windows Mobile. The rugged PDA provided with the SVC HR-768i is an extremely durable, reliable, and lightweight unit. It is waterproof and drop resistant to IP67 and MIL-STD-810F ratings and provides10+ hours per charge.

The compact size and sunlight readable display contribute to ease of operation when acquiring and reviewing collected spectral data. Nonvolatile flash memory guards against the loss of valuable field data while the RS-232 port provides optimum connectivity in the field or in the lab. The Bluetooth wireless communication streamlines field data collections. SVC offers other optional, rugged laptops, tablets and mobile devices.
