LED radiometer SpectraScan® PR-655

The SpectraScan® Spectroradiometer PR-655 is JADAK’s economical portable solution for spectral based photometric and colorimetric light measurements, designed for applications requiring precise light measurements from a range of light sources, such as display monitors and projectors, reflective surfaces, and industrial applications (visual display testing, LED testing, film and video post-production, auto/aerospace displays, and dental color testing). A handheld, completely portable battery powered (Li-ion, USB charger) unit for stand alone operations, the PR-655 interfaces with USB, and optional Bluetooth® or RS-232, with a Secure Digital (SD) port to allow users to store measurement data on removable media. Configured with 128 detector elements, the PR-655 has a wide dynamic range of 0.2 fL to 30,000 fL (without external neutral density filters) and spectral resolution of 3.12 nm per pixel, and spectral range of 380–780 nm, accompanied by an automated measure shutter. Available with standard 1° aperture (optional 1/2°), and 2 sensitivity modes (standard & extended) with 4 measurements speeds: normal, fast, 2x fast, 4x fast. Spectral based photometric and colorimetric measurements, performing white point calibrations of CRTs, LCDs, PDPs and digital projectors Source spectral power distribution Dominant wavelength Correlated color temperature Controls are easy with a state-of-the-art 2.25” x 3” full color high-resolution touch screen LCD display, and 5-way navigation keypad, plus programmable User Profiles for saving setup and preference settings.
