Display LCD size : 59 mm x 34 mm.
Measuring geometry :45° /0° – circular illumination at 45°, measurement at 0°.
Spectral range :400 nm to 700 nm.
Light source :Two white LED lamp.
Measuring principle :For no lighting sample color measurement such as textiles, paper, leathers, painting materials, a defined light source illuminates the sample and the reflected surface light is spectrometrically analyzed.
For lighting sample color measurement, the light source of sample is spectrometrically analyzed directly.
Color sensors :3 color photo transistors :Red photo transistor, Green photo transistor, Blue photo transistor
Measurement :RGB value :R ( Red ) value : 0 to 1023.
G ( Green ) value : 0 to 1023.
B ( Blue ) value : 0 to 1023.
HSL value :Hue value : 0 to 1.000.
Saturation value : 0 to 1.000.
Luminance value : 0 to 1.000.
Repeatability :R (Red) value < 3
G (Green) value < 3
B (Blue) value < 3
Hue value < 0.01
Saturation value < 0.01
Luminance value < 0.01
* Repeatability is specified under the same sample tested 10 times within two minutes.
* Accuracy is specified under after the instrument is calibrated.
Measurement sample material type :Type 1 : No lighting sample material :Such as textiles, paper, leathers.
Type 2 : Lighting sample material :Such as CRT, LCD monitor, LED lamp, lighting lamp.
* The RGB-1002 is designed mainly for measuring the color value of type 1 (no lighting sample). For the type 2 (lighting sample) color measurement just for the reference only.
Buttons :OP button ( Operation button )
CAL button ( Calibration button )
REL button ( Relative button )
RGB/HSL button (Select RGB or HSL value )
Light ON/OFF button
* No lighting sample measurement, select the sensor light to on.
* Lighting sample measurement, select the sensor light to off.
Power off :Auto shut off saves battery life or manual off by push button.
* Power will off automatically after 3 min., if no buttons be pressed.
Low battery :Low battery indicator.
Calibration :Self calibration.
* The calibration white calibration card is included.
Computer Interface :RS 232 PC serial interface.
Operating Temperature :0 ℃ to 50 ℃ ( 32 ℉ to 122 ℉ ).
Operating Humidity :Less than 80% RH.
Power Supply :DC 9V battery, Alkaline type 006P, MN1604(PP3) or equivalent. DC 9V adapter input.
@ AC/DC power adapter is optional.
Power Current :Standby : Approx. DC 6.3 mA.
Measurement : Approx. DC 32 mA. ( 2 SEC. )
Weight :478 g/ 1.05 LB.
* Main instrument and the sensor probe
Dimension :Main instrument : 203 x 76 x 38 mm
