Portable Spectrophotometer DS-700D, High Precision Colorimeter Color Difference Tester. Color Meter For Plastic, Textile, Pigment, Paint, Print, etc. Geometry : d/8, SCI+SCE   1) Excellent repeatability and inter-instrument agreement repeatability : dE*ab≤ 0.04 (max.) and inter-instrument agreement : ≤0.25 Test result is accurate and reliable to ensure the consistency of the measurement data of multiple devices, which can be used for color matching and accurate color communication. 2). Dual optical path highprecise CMOS array sensor The dual optical path design monitors the energy fluctuation of the light source while measuring the sample signal, reduces interference during the measurement, and obtains better measurement repeatability. The usage of large-area dual-array sensors provides higher spectral response sensitivity, and ensures fast measurement speed, accuracy, stability and consistency between multiple devices. 3). Intelligent auto calibration, white tile is made by ZrO2with reflectance more than 90%, no need for frequent whitecalibration. The instrument is placed on the intelligent calibration base, and the instrument can be automatically calibrated without manual intervention through the whitetile on the base. It has changed the current situation that traditional instruments must be manually calibrated with whitetile. The whitetile is made by ZrO2 with reflectance more than 90%, which ensures excellent mechanical strength and weather resistance, and will not be scratched or discolored after long-term use. 4). 360-700nmFull Wavelength Balanced LED+UV The instrument adopts a fullwavelength balanced LED and UV as the illuminant, ensuring sufficient spectral distribution in the visible and ultraviolet bands, and materials with fluorescent can also be measured.
