DIGITAL REFLECTION METER OR BRIGHTNESS METER

(PHOTOVOLT TYPE)

 BRIGHTNESS METER is intended for measuring the Brightness, Opacity and Gloss of the paper.  It is photoelectric measuring instrument, which conforms to the international standards.  Digital readout of the solid state electronic circuit eliminates the possibilities of reading errors and provides high speed operation. 

SPECIFICATIONS:-

   A digital panel meter for displaying the measured value in percentage.

   Measures brightness, opacity and gloss of paper. 

   Brightness search unit measures traditionally reflectance 

   45⁰.0⁰ of paper with white surface backing and deep blue gelatin light filter.

   Opacity search unit measures directional reflectance  45⁰.0⁰

           the paper with black body backing and green light filter.

   Gloss search unit measures the gloss of the paper by providing

the incident light of 75⁰ on sample paper.

   Quartz-tungsten halogen lamp to provide highly stable light source.

   Measuring accuracy : = .01% Brightness, opacity or gloss. 

   Dimension :290 x 250 mm

   Net weight : 10 kg.

CONNECTION:- Power supply 220 +5% volts, one phase 50 Hz 25 Watts.
