IoT Based SR-8800 field spectroradiometer
The SR-8800 uses its IoT operating system to control the pistol grip functionality so that any user can get consistent scans. The IoT uses a WiFi network accessed by an Android device, iPhone or tablet for controlling the system and downloading data stored on the instrument.
The SR-8800 spectroradiometer operates in the 350-2500nm band with high resolution and sensitivity. Of special note is the ability to control your instrument from an IOS or Android smartphone or tablet. In combination with the new Sensaprobe™ grip, researchers can access and store a picture of the sample and its GPS location, in addition to the scan data. An ultrasonic sensor together with live camera view of the sample ensure that your measurements are precise and repeatable.
