Large measuring aperture, higher precision

As it can measure larger area with its large 20mm measuring aperture, the device ensures higher precision on the test results as it acquires more even color data when measuring textured or rough surface materials.

Touch screen makes measurement convenient

The device adopts a 3.5-inch IPS color capacity touch screen, no need to operate by pressing button. It offers smooth user operation experience and interactive interface, simple operation.

Portable and Precise

Portable size, durable and stable architecture with ergonomic design ensures more stable test results.

Providing multiple sets of electronic color charts

The device provides multiple sets of electronic color charts applicable for many industries (RAL, Pantone, NCS), can quickly match 3 closest serial numbers in the color charts with precision rate over 90%,  keeping your hands free from carrying heavy color charts.

Color scan and Color Compare function

LS175 has two main functions: Color scan and Color compare. You can get result within 1 seconds when using Color scan function. Quality Control inspection can be realized in Color compare function that color deviation on 3 Lab color channels will be prompted, offering reference for color toning.

Seven color spaces and six color difference formulas

There are seven color spaces and six color difference formulas for user to choose which meet various measuring demands of different industries.

Mobile App and PC software support

The device is equipped with APP on mobile phone and PC software, covering operation system of Android, iOS and Windows for more powerful functions. It can switch between Chinese and English to meet requirements of different application scenes.

Advanced color sensor, Outstanding quality

LS175 adapts chip-level color sensor AS7261 newly launched by ams AG, whose precise XYZ tristimulus color sensing function simulates the human eye response curve of the standard observer defined in the CIE1931 and CIE1976 color systems.

Measuring locating plate to make measurement more accurate

The instrument is equipped with a measurement locating plate to meet the needs of precise alignment and make the measurement more accurate.

Compensation light path technology

Compensation light path installed in the device enables long circle calibration and stable result.
