MICROPROCESSOR BASED COATING THICKNESS GAUGE
MICRONSTAT, MICRONTEST


MICRONSTAT : A new dimension in
Quality Control and Inspection

For Vital Statistics in Coating Thickness Measurement!
  • Measures coatings and film/foil thickness
  • EMI(FD) and Eddy Current (ND) probes
  • Non-destructive testing
  • Resolution upto 0.1 micron
  • Averages zero for rough substrates
  • Statistical evaluation of data
  • No rotary controls
  • Prints readings and statistical values
  • Aesthetic compact design with rugged ABS housing

These instruments can use both FD and / or ND probes unlike earlier ones where separate instruments were required for ferrous and non-ferrous bases.

MICRONSTAT is a new generation electronic digital gauge for accurate measurement of coating thicknesses. It can measure thickness as fine as 1 micron! This eliminates the need for guesswork, erroneous readings and approximation in coating thickness measurements. It measures following coatings on metallic substrates.

  • Paint, varnish, lacquer, oxide, nitride, phosphate, enamel, plastic, fiberglass, rubber, glass etc.
  • Decorative and protective coatings
  • Electroplating on steel (except Nickel)
  • Anodising, paints, etc., on Aluminium
  • Plastic, Polyester film, Copper, Aluminium, Foil thickness measurement by providing a temporary base like a plate or roller.

MICRONSTAT can help to maintain consistent quality of coatings in the fields of anti corrosion, electroplating, painting of engineering products, automobiles, aircraft manufacture, chemical industry and so on.

STATISTICAL EVALUATION

A series of reading are taken and the statistical data is evaluated to know uniformity of coatings. The standard deviation gives the distribution of coating thickness on either side of the mean thickness. In accordance with "Chebyshev’s theorem" 68% of the readings are within mean thickness standard deviation and 93% within mean thickness 2 standard deviation.

The statistics displayed are :
  1. Number of readings
  2. Maximum
  3. Minimum
  4. Mean*
  5. Standard deviation*

*Resoution 0.1 micron below 100 microns.

Any wild readings can be deleted from the statistical calculations using (CE/C) function in order to avoid any errors.

PRINTER FACILITY

MICRONSTAT can connect to mPRINT : Thickness Printer (plain paper) to print label, all readings and the statistical values. mPRINT operates on rechargeable batteries and uses a reliable Epson print mechanism. RS 232 C or Centronics 8 interface is available for connection to a standard printer.
