Overview
The LS175 is a Handheld large aperture color difference meter of the LINSHANG brand, model LS175. It is designed with a 45 °/0 ° Optical inspection geometry and is equipped with a large measurement diameter of 20mm, which is especially suitable for accurate Color measurement and color difference comparison of textured or rough materials. The instrument is equipped with a 3.5-inch color Touchscreen, which can be operated independently, and has multiple standard Color Charts built in, which can quickly match the closest Color Chart number of the measurement Color. It has QC fast detection function and supports multiple Color difference formulas and threshold settings. In addition, the instrument can be connected to the mobile end APP and computer software through Bluetooth or USB to realize functions such as data management, sharing and report printing.
LS175 is widely used, and its large measurement caliber can obtain more uniform Color data. It is often used in product Color management, color difference quality control and batch inspection of incoming materials in clothing fabrics, leather products, wood furniture, meat food and other industries.

Principle
The LS175 color difference meter adopts a 45 °/0 ° Optical inspection geometry, that is, a 45 ° ring illumination, 0 ° reception. It uses a full Light spectrum LED Illuminant to illuminate the surface of the measured object, and the instrument receives the reflection of the object in the 0 ° direction. Ray of light. Light spectrum data (Wavelength range 400-700nm, interval 10nm) of reflected light is analyzed by the built-in Light spectrum Sensor, and various Color parameters (such as Lab value, etc.) and Light spectrum reflectance Linear dispersion of objects are calculated under D65 Illuminant and 10 ° field of view conditions, so as to achieve accurate measurement of Color and color difference contrast.
Applications
Color measurement and management of products in clothing fabrics, leather products, wood furniture, meat food and other industries, product color difference quality control, batch inspection of incoming materials

Steps
1. Turn it on and warm up.
2. Use a whiteboard to calibrate.
3. Align the instrument measurement port with the measured sample, and use the measurement positioning plate to assist in positioning.
4. Press the measurement button to get the measurement result after about 1 second.
5. View Color data, color differences, or matching Color Chart numbers on the Touchscreen.
6. The color difference threshold can be set through the QC function for batch detection.
7. The measurement data can be stored in the instrument, or exported, shared and printed through Bluetooth/USB connection APP/computer software.
Notice
* The instrument needs to be used under the operating Temperature range (0~ 45 ℃) and Humidity conditions (0~ 85% RH, no condensation).
* Storage should avoid extreme environments (-25~ 55 ℃, 0~ 85% RH, no condensation).
* To ensure measurement accuracy, regularly calibrate with a whiteboard.
* Make sure that the measurement port is closely attached to the sample surface during measurement to avoid light leakage.
* For textured or rough surfaces, it is recommended to use a large measurement aperture and average multiple measurements.
* The instrument battery is a rechargeable lithium battery, please use the matching charger to charge through the USB (Type-C) interface.
* Avoid severe impact or contact with corrosive liquids.
