Colouri Meter I9 (Digital)

OVERVIEWColorimeter i9 is researched and developed in accordance with CIE(International Commission on Illumination). colorimeter is a high precise colorimeter with simple user interface and stable performance. It can be powered by both Li-ion battery and external DC power supply.COLOURI Meter i9 (DIGITAL) adopts innovative technology -- automatic white and black calibration at startup which greatly simplifies the measuring steps. It adopts innovative technology -- camera locating and illumination locating which brings out more precise and quicker locating. colorimeter has been through numerous experiments and tests. It adopts complex advanced algorithms which make measurement performance more stable, more accurate and more compatible. SALIENT FEATURE :This instrument adopts both accurate camera locating and illumination locating and fully considers users' need and adopts user-friendly design. It has original camera locating and illumination locating. User can select it according to the need.The colorimeter adopts auto white and black calibration. The calibration will be done during startup. This function can ensure the precision of this instrument, and it eliminates complex manual white and black calibration which greatly improves the convenient use of the colorimeter. You only need to turn on the colorimeter before performing measurements.The standard deviation of this colorimeter is ???E*a b<0.06 (Average of 30measurements of standard white calibration plate.).The colorimeter is configured Φ8mm measuring aperture, Φ4mmmeasuring aperture and extended aperture (Φ8mm) (optional), which can meet different requirements.The colorimeter adopts international standard illuminate D65, D50 and A. Users can select the light source according to their needs.This colorimeter has various color spaces. The users can select it according to their needs. And the instrument can display Whiteness ,Yellowness and Color Fastness which is used widely.TECHNICAL DETAILS :Display Mode : CIE L*a*b; CIE XYZ; CIE RGB;CIEL*u*v; CIE*C*H;Whiteness &Yellowness; Color FastnessColor Difference : ΔE*ab; ΔL*ab; ΔE*C*H; ΔECIE94; ΔEHunter Formula Illuminating/viewing: 8/d (8°illumination angle/diffuse viewing)geometry Light Source : LED blue light excitationDetector: Silicon photoelectric diodeMeasuring Aperture: Φ8mm; Φ4mm; Φ8mm extended aperture(optional)Measuring Conditions: Observer : CIE 10° Standard Observer Illuminant : CIE Standard Illuminant D65; D50; AMeasuring Range: L: 0 to 100Repeatability: Standard deviation within ΔE*ab 0.06(Measurement Conditions: Average of 30 measurements of standard white plate)Storage: 100 pcs standard samples; 20000 pcs test samplesMinimum Interval: Approx. 1 sec Between Measurement Battery Life: More than 3000 measurementsLamp Life: more than 1.6 million times in 5 yearsDisplay: TFT True-color; 2.8 inch@(16:9)Operating Temperature: -10???to 40???(14???to 104???)Range Storage Temperature: -20???to 50???(-4???to 122???)
