Feature:1. 3.5in Touch Screen: The colorimeter adopts a 3.5in capacitive touch screen, which has a good human computer interface. Built in compensation function, the value is stable, allowing long term calibration2. Multiple Electronic Color Cards: The colorimeter contains multiple electronic color cards, which can quickly match the closest color card number, and the color card matching accuracy rate is greater than 90%3. QC Detection Function: The colorimeter has QC detection function, the color difference threshold can be set, and a variety of color difference formulas can be selected. A variety of color spaces are available to facilitate color measurement for various needs4. Large Storage Space: The colorimeter has a large storage space, which can store 1000 colors and 1000 color difference comparison records. Built in rechargeable lithium battery, can measure 10,000 times continuously after a single full charge5. Connecting to APP: The colorimeter can be connected to a mobile APP, with PC software, which has a better color difference statistical analysis function, and can guide into and export instrument data at the same timeSpecification:Item Type: ColorimeterMaterial: ABSWeight: Approx. 225g/8.0ozBattery: 1 x Rechargeable Lithium Battery 3.7V 4000mAh (built in battery)Uses: Chroma Sampling, Color Difference Detection and ComparisonLighting Method: 45/0 (45 circle lighting, 0 reception)Lighting Source: Full Spectrum LED Light SourceMeasuring Diameter: Approx. 8mm/0.3inMeasurement Conditions: Light Source D65, Field of View 10Measurement Time: About 1sColor Spaces: Color Model, Luv, LCh, Yxy, CMYK, RGB, HexColor Difference Formula: E*ab, Euv, E*94, E*cmc(2:1), E*cmc(1:1), E*00Repeatability: Standard Deviation E*ab within 0.03 (measurement conditions: after warm up correction, measure the average value of 30 whiteboards at intervals of 3s)Battery Power: 1 x Rechargeable Lithium Battery 3.7V 4000mAh, Can Measure 10000 Times Continuously After a Single Full ChargeDisplay: 480 x 320 Dot Lattice IPS Color ScreenSystem Language: Simplified Chinese, English Charging Interface: USB (type c)Data Transmission: USB, BTOperating Temperature Range: 0-45, 0-85%RH (non condensing)Storage Temperature Range: -25-55, 0-85%RH (non condensing)Storage Space: Color x 1000 Color Difference Contrast x 1000Color Threshold: Can Be SetCompensation Light: Built inChromatic AberrationIn the Color Difference Contrast Measurement Interface, Click the "standard Color Measurement" Button, and the Current Measured Value is Used As the Standard Color. Click the "sample Color Measurement" Button, the Current Measured Value is Used As the Sample Color. if You Press the Instrument Button for a Short Time, a Color Measurement Will Also Be Performed, and This Measurement Value Will Replace the Previous Measurement Data.When the Standard Color is Measured or Added, and the Sample Color is Measured, the Color Difference Between the Two Colors is Calculated. the Color Difference Comparison Results Generally Have the Following Three Judgments:LabCh DifferenceThe LabCh Difference Value a is the Sample Color Data Minus the Standard Color Data, and the Color Cast Direction Between the Two is Judged by AL, Aa, and Ab.Value of AEThe Value of AE is Calculated According to the Selected Color Difference Equations.QC TestingQC Detection is Suitable for Color Difference Detection in the Production Process. if the Calculated Ae is Greater Than the Set Threshold, It Will Display "unqualified", and the Judgment Area Will Display Red; if the Calculated AE is Less Than or Equal to the Set Threshold, It Will Display "qualified , the Judgment Area is Displayed in Green.4.BT Connection1.

When the instrument has not been used for a long time, it is recommended to perform calibration before use.2. Please ensure that the sample is uniform and the appearance is flat and clean, otherwise it will affect the measurement accuracy.3. After the base is removed from the host, it should be stored in a clean place to avoid contamination of the standard board.4. Do not insert any object into the instrument to clean it, which will damage the instrument and affect the measurement accuracy and operation safety.5 When the battery of the instrument is empty, it should be charged in time.6. If the instrument is not used for more than half a year, it needs to be charged regularly to prevent the battery from being damaged by over discharge.7.
