Spectral Evolution NaturaSpec™ Plus Portable Spectroradiometer

NaturaSpec Plus: Advanced Features for Fieldwork Excellence

The new NaturaSpec Plus spectroradiometer is meticulously engineered for fieldwork, featuring Spectral Evolution’s exclusive Sensaprobe+.

Key features include a 6” touchscreen Windows tablet with DARWin software, a field-swappable internal battery, and a smart power switch that seamlessly transitions between external and internal batteries for extended operation. It also boasts a quick release fiber optic mount, ergonomic grip for enhanced comfort, built-in inclinometer for precise scan angles, real-time targeting camera, ultrasonic distance sensor for accurate target measurement, and trigger activation for easy scan initiation.

The NaturaSpec™ Plus Key Features

The NaturaSpec Plus spectroradiometer stands out in the Remote Sensing Series for its advanced features and fieldwork optimisation. Compared to other models like the PSR-1100f, RS-3500, and PSR+, the NaturaSpec Plus offers superior signal-to-noise performance and high spectral resolution, making it ideal for precise data collection in remote sensing applications. 

The NaturaSpec™ Plus Key Features

  • Sensaprobe+ with a 6” touchscreen Windows tablet and DARWin software
  • Field Swappable Internal Battery
  • Smart Power Switch: Manages power between external and internal batteries, allowing extended operation time
