The instrument is made in accordance with the development of the international CIE standard for color difference measurement.
It is in line with international standards. It can rapidly and accurately measure color contrast value from the same material ,and uses the LCD display technology to make sure easy understanding.
The instrument can be used to measure color contrast value from the same material accurately, i.e E, L, a, b, Lab and Lch value.
|
Color difference (tolerance) |
0-0.25△E | Very small or none; ideal match |
0.25-0.5△E | Tiny; acceptable match |
0.5-1.0△E | Slight to moderate; acceptable in some applications |
1.0-2.0△E | Moderate; acceptable in certain applications |
2.0-4.0△E | There is a gap; acceptable in certain applications |
4.0△E or above | Very large; unacceptable in most applications |
