Liquid Limit Device (With Counter).

Casagrande method in mechanical form is known as liquid limit method and has been in use for soil mechanics for a number of decades.

The liquid limit data of soils is useful to correlate mechanical properties of soil, such as compressibility and lower shear strength. Liquid limit is the water content at which soil passes from zero strength to an infinite strength, hence the true value of liquid limit cannot be determined. For determination purpose liquid limit is that water content at which a part of soil, cut by a groove of standard dimensions, will flow together for a distance of 1.25cm under an impact of 25 blows in a standard liquid limit apparatus. The soil at the water content has some strength which is about 0.17N/cm. sq. (17gms/sq.cm.) . At this water content soil just passes from liquid state to plastic state. It consists on a brass cup held on an adjustable bracket.The cup can be adjusted for a fall of 1 cm and can be raised an dropped on a rubber base of standard hardness by cam action. Complete with one Casagrande grooving tool, one ASTM grooving tool and a height gauge block. civil lab equipments manufacturers

Wavelengths And Frequencies With A Quincke Tube Multimeter.

Principle: When a sound wave of a particular frequency is divided into two coherent components (like, for example, light waves in an interferometer experiment), and if the path of one of the component waves is altered, it is possible to calculate the wavelength of the sound wave and its frequency from the interference phenomena recorded with a microphone. Tasks: Record the extension of a Quincke tube for given frequencies in the range 2000 Hz to 6000 Hz. Calculate the frequencies from the wavelengths determined and compare them with the given What you can learn about: Transverse and longitudinal waves Wavelength Amplitude Frequency Phase shift Interference Velocity of sound in air Loudness Weber-Fechner law civil lab equipments manufacturers

Crock Meter (Motorized).

Crock Meter (Motorized) - One of the tests for determination of color fastness of dyed leather is the crocking test. This test is used for the determination of colorfastness against rubbing, either under dry or under wet conditions. In this test a moving brass finger of specified shape and size rubs against the test specimens under a fixed load. The amount of color transferred to a piece of abradant fabric fixed over the base of the moving finger is graded either against the amount of color transferred by a standard leather sample under identical conditions, or by visual rating of amount of color transferred during dry and wet rubbing. The Crockmeter (motorized model) consists of a rigid flat metallic platform on which the test specimen can be held firmly and an abrading finger that rubs against it under a specified load. The platform is fixed over the base of the equipment and lies in a horizontal plane. The test specimen is held firmly over an abrasive paper, which is pasted on the upper face of the platform, with the help of two pressing pins holding it at both ends. The abrading finger has a flat circular rubbing face, which is covered with a piece of white rubbing fabric during the test. The rubbing fabric picks up color lost by the test specimen during rubbing. It is held over the finger with the help of a spiral spring. civil lab equipments manufacturers

Traverse Thread Counter For Testing Lab Workshop.Traverse Thread Counter - For Testing Lab One of the most common measure of the quality of a fabric is the number of threads per unit length in both the warp and weft directions, or its picks and ends. Picks and ends of any fabric are normally determined with the help of an ordinary counting glass having a square or rectangular opening of specified size. However, when a greater degree of accuracy in determination of picks or ends is needed, or the weave is too fine to be checked with an ordinary counting glass, this counting is carried out with the help of a Traverse Thread Counter. In this apparatus a traveling microscope is used for viewing the weave of the fabric under test. Openings of known widths are provided to enable picks and ends per unit length to be determined, both in metric and imperial systems

Drape Meter Testing Equipment For Testing Lab Workshop.Drape Meter Testing Equipment - For Testing Lab Drape Meter Testing Equipment is defined as the extent to which a fabric will deform when it is allowed to hang under its own weight. It is one of the subjective performance characteristics of fabric and contributes considerably to its aesthetic appeal. It is a complex characteristic involving both bending and shearing deformation. One of the methods of determining the drape characteristic in which both the warp and weft way characteristics interact to produce a graceful fold uses a circular support over which a specimen of the fabric in form of a circular piece is placed with an annular section overhanging the support. The horizontal area covered by the shadow left by the overhanging portion of the fabric is determined and compared against its actual area to obtain the drape co-efficient.
