Specific Gravity Balance

Range 0.9 to 3.0

The Specific gravity of any elastomer is of considerable importance for its identification and can also be used for providing a rough assessment of its physical properties. The Presto Specific gravity balance is highly beneficial in evaluating rubber and various rubber products. It is widely used in the rubber industry. The Presto Specific gravity balance can also be used for finding if the sample and the products are prepared from the same compound or not. The instrument directly displays the specific Gravity digitally. The Presto Specific gravity balance is based on the Archimedes principle. It is specially designed for use in laboratory applications. Its easy two-button operation makes operation simple and user friendly. The instrument is provided with a high-contrast LCD display. It comes complete with an instruction manual and calibration certificate traceable to NABL approved laboratories.

Crocking Meter

Size of sample 195*60 mm
Diameter of rubbing finger 16 mm

Crockmeter is a unique test instrument to determine the colorfastness of textile materials against rubbing under either dry or wet condition. It checks the colorfastness to crocking when the test specimen is subjected to continuous rubbing by an abrading finger which rubs against it under specified load. The rubbing finger has a flat base which is covered with a piece of standard white crocking cloth, which in turn is held by a stainless steel spring clip and is made to move over the test sample in an oscillating motion. The crocking cloth picks up the color lost by the sample under test. Crock-meter is an instrument which is widely used to determine the color fastness to rubbing of textiles, fabrics, yarn or leather under either dry or rub conditions. It is designed and produced according to both AATCC and ISO standards, so it can evaluate color fastness for textile fabrics, dyed textile or dyed leather. The Change in the color of specimen and staining of the adjacent fabrics are assessed with standard gray scales.

Beesley Balance

Beesley balance is used for measure the direct yarn count. The balance is made of an aluminium beam which is pivoted at a bracket with the help of two jewel bearings. One end of the beam has a stainless steel hook for putting the yarn. The pointer side of the beam is provided with a slit for placing the weight. The beam assembly is fitted in a sheet metal box which has a sliding transparent window for avoiding the air flow in the instrument. A template is also provided with the instrument for cutting the different size of the fabric material. The instrument comes complete with two weights, an instruction manual and a calibration certificate traceable to NABL approved labs. The instrument is chrome plated & dark gray metallic paint for given the corrosion resistance finish. Once the fabric is made and during the process of weaving bleaching dyeing etc. the yarn count decreases increases. Hence to determine count Beesley Balance helps to determine yarn count of fabrics. The count of yarn is defined as a number indicating its Weightage.

Gloss Meter

Range 0-10GU 10-100GU 100-1000GU

The gloss meter is available in different geometries to measure the specular reflection gloss of a surface or a material. The Gloss Meter Tri-angle is used to determine the gloss on a surface and measures the amount of reflected light. The gloss measurement tool is available in different geometries depending on the type of surface. The Gloss Meter Tri-angle is used on various types of materials like ceramics, paint, paper, plastics, and metals. The instrument is portable, compact, accurate and sensitive available in different models; mains operated laboratory purpose and handy battery operated for measuring the geometry 20, 60, 85 degrees angles. The tool is used to measure the brightness or whiteness of plantation white sugar as well as measures the reflectance of fabrics. The test provides good correlation with visual gloss or shining of the flat object. The correlation reduces if the sample changes from being flat. The testing procedure has an extensive use to measure partially the surface quality and shining appearance.

Traverse Thread Counter

Fabric can be checked in slot sizes ½ Inch, 1 Inch, 10mm, 20mm, 50mm
Digital Counter 4 – Digits pre-settable Digital Counter

One of the most common measures of the quality of a fabric is the number of threads per unit length, in both the warp and weft directions (wrap is the yarn woven in the vertical of the fabric & weft is the yarn woven across the width horizontal of the fabric lengthwise). The Traverse Thread Counter utilizes a motorized traveling microscope, for viewing the weave of the fabric under test. Openings of known widths are provided to enable picks and ends per unit length, which is determined both in Metric and Imperial Systems. Traverse Thread Counter is a simple model with modern stylish aesthetics. All other parts are made of Stainless Steel; its robust construction ensures trouble free, life long operations. A 10x traveling microscope is in-built; with reference line inside it to magnify the fabrics for accurate checking of the specimen thread. Two filament illumination arrangements are provided on the basic plate, which has translucent plastic panel for the effective view of the specimen.

Textile Moisture Meter

Presto Digital Moisture Meter is used for every Textile material, irrespective of its form (i.e., Fiber, Yarn, and Fabric). All textile materials contain water, which is expressed in terms of moisture percentage. Wool has got the highest moisture content and synthetic fibers contain the lowest moisture content. It is based on the principle - moisture content is determined by measuring the electrical conductivity of the material, which always is proportional to the content of the moisture. Digital moisture testers are used to measure moisture content of textile & yarns samples quickly & effectively. Digital Moisture Meter measures moisture by sensing the electrical resistance of the hygroscopic material. The section of sensor depends upon the form of the material. The sensing can be done with one of the three types of electrodes :-Pin Type Sensor (Small Pins) : It is used for loose Cotton materials cones, cheese.Pin Type Sensor (Long Pins) : The Sensor with long Pins is used for Cotton Bales.
