The WD-10DC All Digital Colorimeter is based on all digital integral photometric and colorimetric measurement technology. It has no analogue unit, thus it is very simple to overcome the zero drift which is impossible to be avoided in current colorimeter. The digital X(l), Y(l), Z(l) sensor has large dynamic range so that there is no range-changing error in it, moreover, it possesses strong anti-interference ability and high accuracy. The WD-10DC All Digital Colorimeter contains internal RS232 computer interface, the calibration is done by software. It is suitable for monitoring and remote applications. The WD-10DC All Digital Colorimeter software can calibrate the instrumentation, sample the data through RS232 interface and print out the results. It can also be calibrated by other standard light sources to obtain very high measuring accuracy of x, y color coordinate and color temperature. It is a real-time measuring system and run under Windows98/NT. Application: High speed measurement for illuminance, correlated color temperature etc. Of incandescent lamp, halogen lamp, CFL, HID, LED, LCD screenSpecification: Illuminance: (vertical) Relative spectral sensitivity error of digital V(l) sensor: F1<± 5.5% Dynamic range: 0.1-50, 000 lx Accuracy: <± 4% Sensitivity: 0.001 lx Repeatability: 0.001 lxColor Coordinate x, y, u, v, u', v': (vertical illuminance>5 lx) X, y: ± 0.002 (CIE Standard Source A, 500lx) Repeatability: ± 0.0005 (CIE Standard Source A) Others: One range, no range-changing error Temperature effect: -0.1%/° C Refreshing frequency: 1n/s(>=10 lx ), 1n/3s(<10 lx ) 128*64 lattice LCD display RS232 computer interface and software Data hold function Power supply: 9V battery Size (L× W× H): 135× 72× 33(mm)
