Digital Photometric Colorimeter

Overview

This Digital Photometric Colorimeter utilizes advanced digital integral photometric and colorimetric measurement technology, eliminating the need for analogue units and effectively addressing zero drift issues inherent in current colorimeters. The digital X (λ), Y (λ), Z (λ) sensor features a broad dynamic range, eliminating range-changing errors, and offers robust anti-interference capabilities and high precision. The CHC-I model includes an internal RS232 computer interface, with calibration performed via software. It is ideal for monitoring and remote applications, allowing data sampling through the RS232 interface and result printing. Calibration with standard light sources ensures high measurement accuracy for x, y color coordinates and color temperature. Operates in real-time under Windows System, featuring a 128×64 lattice LCD display, RS232 computer interface, and software with a data hold function.
