Overview
Emissions and Stack measuring instrument handheld colorimeter Excellent repeatability and inter-instrument agreement repeatability d E x 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. Dual optical path high precise 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. Intelligent auto calibration, white tile is made by ZrO2 with reflectance more than 90%, no need for frequent white calibration. The instrument is placed on the intelligent calibration base, and the instrument can be automatically calibrated without manual intervention through the white tile on the base. It has changed the current situation that traditional instruments must be manually calibrated with white tile. The white tile is made by ZrO2 with reflectance more than 90%, which ensures excellent mechanical strength and weather resistance, and will not be scratched or discoloured after long-term use. 360 nm to 700 nm Full Wavelength Balanced LED+UV The instrument adopts a full wavelength 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. 10nm Resolution Grating Spectroscopy Technology The grating combined with the array sensor made by the innovative MEMS process makes color measurement more accurate based on the 10nm spectral resolution.
Three aperture as standard accessories, no tools are needed, and apertures can be replaced at any time to meet different sample measurement requirements Spectrophotometer DS 700 D comes with three apertures 0.43 in (11 mm) or 0.24 in (6 mm) or 1 x 0.12 in (3 mm). It supports Android, IOS and Windows program. It is with the camera to see the measurement area clearly.
