Portable Grating Spectroradiometer
MS-720

Portable spectroradiometer MS-720 is developed to measure the spectral irradiance in the range from Visible to Near-Infrared region. MS-720 is mainly used for the data acquisition for Geological features, Vegetation, Oceanography, Remote sensing and others.
MS-720 is hand-heid instrument with an integrated LCD and an intemal memory. Therefore, it's suitable for the outdoor stand-alone measurement. A small-sized grating s~ectrometer is int~grated. Spectral irradiance is measured by using diode array.
The data can be downloaded to PC using the attached software "720Man.exe", and the data can be saved and edited in the PG. "720Man.exe" calculates the integral radiation irradiance and compares the data with the reference data.

l. Portable
MS-720 is portable (WIOO x Dl6S x H60mm. 720g) and suitable for the outdoor measurement. The operation is easy with the integrated LCD and the tact switch.

2. Long stability
The less aging diffuser, grating spectrometer and diode-array are adopted in MS-720. MS-720 is durable because there is no movable part to change the spectrum. This is accomplished by the adoption of diode-array. MS-720 software a utomatically deterrnines the optimal shutter opening time for the spectral measurement based on the respective spectral intensity.

3. Substantlal software functions
Both "Catalogue View" of the plural spectral data and the "Detailed VievV' of the single spectral data are available by MS-72C analysis software 720Man.exe. 720Man.exe. saves the spectral data of inm and 5nm inten/al. It also compares the data with the reference.
