LANDTEK WM-206 Integral Type Whiteness Meter

The WM-206 is the integral (one-piece) model of the LANDTEK WM whiteness meter series. It directly measures the whiteness value of objects or powders with a flat surface, and is widely used in textile printing and dyeing, paint, chemical building materials, paperboard, plastic products, white cement, ceramics, enamel, talc powder, starch, flour, salt, detergent, cosmetics and other substances.

The instrument consists of a light source, optical system, detection system, data processing and display system, and calculates blue light whiteness R457. Its long-life 457 nm LED light source conforms to the light source requirement of the JJG 512-2002 National Metrological Whiteness Meter Verification Regulation. The diffuse reflectance of the sample surface is received by a photocell, amplified by a high-precision auto-zeroing operational amplifier and energy-calibrated, and the whiteness value is shown directly on the display.

The WM-206 measures through an 18 × 11 mm rectangular aperture with 45/0 illumination, runs on a lithium battery and is supplied with an AC adaptor and a standard white board.
