Grindometer Scraper Blade

Fineness of Grind Application

Product Description:

Qualtech Products Industry precision GrindometerFineness of Grind Gauge – is a professional instrument to measure the particle size of suspensions including paint, coatings, printing ink, pigments, paper, ceramics, plastic, pharmaceuticals, foods and related sample materials. This professional Grindometer consists of a precision engineered hardened stainless steel Grindometer Base with a Single Channel, Double Channels or Wide Channel carved into its surface combined with a precision engineered Scraper Blade.

This professional Grindometer – Fineness of Grind Gage – presents graduations in Microns, Mils, NS (Hegman) on the top surface for user-friendly application and easy reading of sample test results.

This precision Grindometer and Fineness of Grind Gauge is used to indicate the Fineness of Grind or the presence of coarse particles or agglomerates in dispersions and suspensions – heterogenous mixtures containing solid particles to control the production, storage, and application of products which are milled or grinded during the production.

The sample liquid is poured into the deep end of the Channel or Groove and is distributed with the Scraper Blade towards the flat or shallow side of the Channel which is carved into the Grindometer – Fineness of Grind Gauge – until the largest particle size present in the sample liquid is equivalent to the depth of the groove of the Grindometer.

This precision Grindometer and Hegman Gauge offers the advantage to determine the largest particle size and possible irregularities present in dispersions and suspensions fast, efficient and with the use of only very small amounts of sample liquids.

This precision Grindometer – Fineness of Grind Gauge – is engineered in accordance with international test standards including:

Grindometer – Advantages:

  • Precision Engineered
  • High Accuracy & High Precision
  • Leather pouch
  • Reliable Design
  • Hardened Stainless Steel to ensure longevity
  • Easy to use
  • User-friendly application
  • User friendly cleaning
  • Engineered in accordance with international test standards
  • Calibration Certificate
  • Graduated in Microns, Mils, NS (Hegman) (Please specify when ordering)

Fineness of Grind Gauge – Scales:

This precision Grindometer – Fineness of Grind Gauge – offers graduations in Microns, Mils, NS (Hegman):

  • 1 mil = 25.4 microns
  • 1 mil = 0.001 inch
  • 1 micron, μm = 0.001 mm or 10-6 m

The Hegman scale or National Standard scale (“NS”) presented on this precision Grindometer and Fineness of Grind Gauge shows a range from 0 to 8 NS with numbers increasing as the particle size decreases.

  • 0 Hegman = 100 microns particle size
  • 4 Hegman = 50 microns particle size
  • 8 Hegman = 0 microns particle size

Automatic Fineness Grind Gage

Automatic Fineness Grind Gauge

Automatic Grindometer

Product Description:

Qualtech Products Industry precision Automatic Grindometer is a new and reengineered Fineness of Grind Gauge to assist with measuring the particle size of samples by performing an automatic and electronically controlled precision motion when automatically moving the Grindometer Blade across a Fineness of Grind Gage to ensure an increased accuracy and an increased repeatability of your particle size measurements for research and quality management.

Maintaining the familiar visual sample evaluation method applied when manually completing sample tests this Electronic Grindometer increases the accuracy and repeatability of sample tests performed with a Fineness of Grind Gage by always maintaining the same preset speed, the same preset test load and the sample preset angle of the Grindometer Blade when moving across the Fineness of Grind Gage. This helps to reduce or to prevent sample measurement errors which may occur between sample tests when manually moving the Grindometer Blade, especially when different operators may manually perform slightly different Blade motions with different speeds, different test loads and different angles which may lead to slightly different test results throughout test series and cause a reduced accuracy and a reduced repeatability.

This Automatic Grindometer is designed and engineered offering the newest microchip technology combined with a comfortable to read LCD display with backlight, an integrated precision motor, user-friendly programming, adjustable test loads to conveniently preset the preferred load of the Grindometer Blade and an open sample area which fits with most available Fineness of Grind Gages to ensure that your currently available Fineness of Grind Gauges very likely fit with this professional Automatic Fineness of Grind Gage.

This Automatic Grindometer is an electronic instrument made of high quality stainless steel to ensure the longevity of your instrument combined with an integrated precision motor operating similar to a robot arm, which automatically moves the Grindometer Blade across a Fineness of Grind Gauge always performing the very same precision motion which can conveniently be preset by the operator. This robot precision motion of the Grindometer Blade ensures that the Grindometer Blade always moves with the same test load, the same speed and the same angle across the Fineness of Grind Gauge to ensure high accuracy and high repeatability of your sample evaluations.

This Automatic Grindometer is ideal for liquid samples, fluids and suspensions including coatings, ink, pigments, chemicals, pharmaceuticals, chocolates, food and related sample materials.

This professional Motordriven Fineness of Grind Gage is suitable for Single Channel Fineness of Grind Gages, Double Channel Fineness of Grind Gauges and Wide Channel Grindometers and it can conveniently be used with Qualtech Products Industry precision Fineness of Grind Gages and it might fit with the Grindometers which you are currently using as well.

This professional Automatic Grindometer – Fineness of Grind Gauge – is engineered in accordance with international test standards including
