Our Products
Our offered Product range includes Automatic Digital Bitumen Penetrometer, Semi-Automatic Penetrometer, Infrared Moisture Meter, Speedy Moisture Meter and Plastic Limit Set.
The Automatic Electronic Penetrometer is used for determination of the needle penetration according to EN 1426, ASTM D5 and AASHTO T49 standards. The penetration depth of the needle is determined with a pulse type electronic measuring system, which is separated from the plunger during the test, this allows the free guidance of the plunger which virtually eliminates friction during the test.Before each start of the test the measuring system automatically resets, and then the penetration needle moves down to the sample by using the electric drive, the needle position can be finely adjusted by using the joystick located on the front panel. A magnifying glass and an ultra- bright LED lamp are supplied to assist the operator; the plunger is then automatically released onto the sample and raised automatically after the testing period. The test result is displayed on the digital display. The plunger can easily be removed to calibrate its weight.A water bath and a thermometer (IP38, ASTM 17C or 63C) required for the test are ordered separately.
The Automatic Electronic Penetrometer is supplied complete with;Penetration Needle, 1 pieceTransfer DishSample Cup, 5535 mm, 6 pieces, stainless steel

he Semi-Automatic Penetrometer for Liquid Limit consists of a cast iron base with course and fine leveling screws, a digital penetration measurement gauge 0.01 mm resolution/readability and an automatic penetration timer unit. The is equipped with a digital, 99 second timer, which can be set to the standard 5 second free-fall time or to some other setting for customized tests. When engaged the timer will allow the needle to free fall into the sample for the specific time interval and then lock the needle from advancing while providing a direct reading of the test results 320 g weight should be added to the 30 angle cone to get a total weight of 400 g for the shear strength test.

This moisture meter has been designed for rapid and accurate determination of the moisture content of a wide variety of materials.
It is moisture wire instruments, the torque being applied to one end of the wire be means of calibrated drum to balance the loss of weight as the test sample dries under infrared radiation. The speed of drying (about 30 min) thus obtained, combined with the friction less balancing system gives the thus obtained, combined with the friction less balancing system gives the result as accurate as those obtained by standard oven drying method. Since drying weighing are simultaneous, It is useful specially for determination of moisture in substances that quickly reabsorbs moisture after drying. The infrared radiation is controlled by a voltage regulator and hereby provided excellent heat control. The instrument is provided with an indicator lamp, which glows when the unit is switched on.
The torsion balance has built-in magnetic damper or reduce pan binration sthat enables quick weighing. The balance scale (drum) is divided in terms of moisture percentage on wet weight basis, which are read directly from it. Graduations are form 0 to 100% in 0.2% divisions, but readings may be estimted to 0.1% moisture content.
Suitable for operation on 220 V, 50 Hz, Single phase, AC Supply,
Capacity : 5g approx.Sensitivity : 10mg approx.Range : 0 to 100% moisture content on wet weight basis.Reading accuracy : 0.20%Probable error : 0.25% in the lower range upto compared to 25% and 1% for moisture contents.Oven methods : above 50%The Equipment consist of the following replaceable parts:
Using a speedy moisture meter, the moisture content of soil, sand and other fine grained material can be obtained quickly with reasonable accuracy. The test technique is based on the fact that water will react with calcium carbide to form acetylene gas and the quantity of gas formed is directly proportional to the water present, leaving a surplus of the chemical used in the test. The quantity of acetylene gas produced is indicated on a built-in pressure gauge which is calibrated in percentage of moisture on wet weight basis. A conversion formula gives the corresponding moisture content based on dry weight.
Moisture contents at which soil has smallest plasticity is called limit. For determination purpose plastic limit is defined as the water content at which a soil will just begin to crumble when rolled in to a thread of 3mm dia.
Specification:-Note:- Glass Plate size 500 x 500 x 10mm can be supplied at an extra cost.
