Product Description:
- Digital whiteness meter is mainly applied to the non-colored surface or near-white flat whiteness measurement object or powders, can be obtained accurately consistent with the sensation level of whiteness.
- For the opacity of the paper can be accurately measured.
- WSB-1 digital whiteness meter measurement accuracy, beautifully designed, easy to carry.
- Ideal for laboratory, out of a sample quality control, field, flow of work purposes.
Summary of functions :
The WSB series whiteness degree instrument with the digital display is mainly applicable for the measurement of the whiteness degree on the surface of the object or the powder in the white color and the color close to white. The whiteness degree can be accurately educed that is consistent with the visual degree. The opacity degree of the paper can also be accurately measured.
This instrument can be widely applied for the measurement of the whiteness degree of the objects like textile & printing & dying, oil paint & dope, chemical construction material, paper & paper plate, plastic product, white cement, ceramics, porcelain enamel, porcelain clay, French chalk, starch, flour, salt, wash, and cosmetics, etc.
Product Characteristics :
a)AC & DC power supply, low power consumption, cabinet and handsome contour design, facilitating field and lab use;
b)Configured with auto power-off function and low power dissipation circuit, able to effectively prolong service life of battery;
c)Adopting big-screen highly transparent LCD display, with comfortable reading, and free of ill influence from sunlight;
d）The simple operation, and can accurately measure the opacity degree of the paper
e ） Adopt the standard white plate rated by the central government to convey the standard value, and the measurement is accurate and reliable
f）Configured with output port of measured values, possible to connect with recording meter
