Description
Description
The Linshang LS171 D/8 colorimeter measures reflected surface color using diffuse illumination with an 8-degree viewing geometry and the specular component included. Its 8 mm aperture suits uniform measuring areas on paint, plastics, coated metal and other suitable surfaces.
OLED readings with an expanded app workflow
The built-in OLED allows the LS171 to be used independently for on-device readings. Connect it to the LSColor app by Bluetooth to work with electronic color charts, personal color libraries, data sharing and color difference comparisons. The app is available for compatible Android and iOS devices.
Use the same instrument geometry and measurement conditions when comparing a reference with a production sample. D/8 with SCI and 45/0 are different optical arrangements; their readings should not be assumed to be identical on every surface.
Set a reference and a QC tolerance
The app compares measured colors with a sampled or stored reference, using a selected color difference formula. Set the tolerance to match your own application before using the pass/fail result. Lab deviation indications show how a sample differs from the reference and can guide further investigation.
Electronic chart matching suggests nearby color codes, while personal libraries retain measured sample values for later comparison. Neither the nearest chart code nor the on-screen swatch guarantees a physical match or provides a paint formulation. Judge the measured values and physical samples together.

Keep the reference tile and surface consistent
Calibrate using the white tile in the closed bottom cap, and keep the tile free of dirt. Measure a flat, clean and uniform area with the aperture fully in contact. A locating plate helps align the aperture with a chosen sample area.
Repeatability of ΔE*ab ≤ 0.03 applies to the stated calibrated white-tile test, not every material or comparison. Recalibrate after extended storage. Phone display differences can affect the visual appearance of the app swatch, so numerical comparisons should use consistent settings.
