Product Features at a Glance:
From optics to enclosure, the entirety of the new NaturaSpec Plus spectroradiometer is engineered for fieldwork with these new instrument features.
- Field Swappable Internal Battery
- Smart Power Switch – The NaturaSpec Plus has been designed with a smart power switch to manage how the instrument is powered between external power and an internal battery. You can now use the instrument with two batteries connected (internal and external) and double the operation time in the field. The instrument will use the external battery first and then when drained seamlessly switch over to the internal battery.
- Quick release fiber optic mount.
- Ergonomic grip for comfort and control by increasing support at the palm.
- A built-in inclinometer that allows the user to monitor scan angles and notifies the user when they are at nadir, so they know it’s ok to scan.
- A built-in camera for real-time targeting and capturing what is being scanned.
- Ultrasonic distance sensor measures the distance from the target and automatically shows the viewer the exact target area, accounting for field-of-view. The camera image is adjusted to automatically represent exactly what is being scanned.
- Trigger activation to start a scan.
The NaturaSpec™ Plus isn’t just another spectroradiometer—it’s your field-ready partner for precision, reliability, and next-level spectral performance.
