MK350S - UPRtek

MK350S

UPRtek MK350S advanced spectrometer is a handheld measuring instrument for calculating the absolute or relative irradiance of many different light sources. It can do photometric measurements (in milliwatt per square metre, illuminance…), color parameters (including X, Y, Z , u’, v’, C.I.E chromaticity coordinates, correlated color temperature, color rendering index (Ra / R1~R15), TM-30-15, color quality scale, and the television lighting consistency index ), and features such as dominant wavelength, peak wavelength, and scotopic-to-photopic ratio, develops and produces industrial applications for commercial lighting, architecture lighting design, green house light penetration and color analyses.
•Give a unique function and highlight the differentiated to meet consumer demand.

  1. More than 46 light unit-of-measures to choose from.
  2. Illumination distribution charts provide assistance in fixture design.
