Whiteness Meter LWM-A12

Labtron LWS-A12 is fully capable of measuring the whiteness of a wide range of powders. It is designed to handle fine particulate samples and provides reliable and accurate readings under normal testing conditions. Specifically, powders with particle sizes approximately between 120 µm and 200 µm fall well within the operational capability of the instrument. However, samples that are exceptionally coarse—such as those resembling the size of rice grains or beans—may not yield accurate readings and are generally not recommended for whiteness measurement using this device.

Yes, the standard package of the Whiteness Meter LWS-A12 includes calibration material. This material allows users to perform routine checks and adjustments to ensure measurement consistency and accuracy. You can use it to verify that your device is stable before conducting your whiteness measurements, even though a formal certificate is not provided.

Inline meters typically share core measurement principles with benchtop models but are ruggedized and designed for continuous operation. They include automated calibration routines, UV compensation, and centralized data logging to maintain quality without manual intervention—making them ideal for large-scale manufacturing.

Labtron supplies advanced whiteness meter LWM-A12. For powders, starch, sugar, or granules, compaction into a tablet or insertion into a powder sample holder is required before measurement. Ensure homogeneous particle size and consistent packing density to avoid air gaps and uneven surface reflection. Many instruments specify sample mass (e.g., ??5?g) and container dimensions to standardize readings. Thorough shaking and leveling of the powder improves repeatability, and cleaning the aperture after each measurement prevents residual interference
