Spectral Color Illuminometer

I. Product Introduction

The HD350 series spectral color illuminance meter adopts a high-speed CPU processor, a Linux operating system and a high-precision electronic CCD optical sensor, and is developed on the principle of a telephoto crossed asymmetric CT spectroscopic system. It features a lightweight design, stable performance, high accuracy, high cost-effectiveness and easy portability, and is equipped with a 5.0-inch HD capacitive touch display so that you can operate it as familiarly as a mobile phone. It completely overturns the concepts of huge volume, cumbersome operation and high price of old-style high-precision spectral analyzers. It can sample and measure light-source parameters anytime and anywhere; combined with PC software it can efficiently analyze and process test data. With extremely high measurement linearity and accuracy, it is widely used in on-site lighting measurement fields such as homes, shopping malls, schools, hospitals, factories, greenhouses and outdoors. It can also be used in the R&D of light-source products and in production-line quality monitoring.
