Introduction:

Measuring the line loop contact resistance by bridges is not the ideal method as thetest current is only a few milli amperes. Thus the value is not the true value of thecontact resistance. VT is a direct reading tester, and uses a DC test current,resulting in true value and accurate measurements. ‘VT’ testers adopts digitalcircuit technique and is used for measuring contact resistance of switch controlequipments at test current of 100A/200A DC. The measurements are accurate asthe test is highly stable. VT-series is a new, fully automatic micro controlledtester that measures contact resistance at 100A/200A DC with built in printer.VT-series is micro controller operated user friendly, accurate, reliable, small, lightweight and reliable tester. It incorporates a large LCD screen for display of menuand results. The results are printed on built-in printer after the test is over. Itincorporates break through technology and design that gives accurate and reliable
results, again and again RS 232 link is also provided.

Principle:

Current of 100A/200A DC is passed in the contact and voltage drop across thecontacts is sensed, processed and the resistance is displayed on screen. VT-seriesis micro controller operated user friendly, accurate, reliable, small, light weight andreliable tester. VT series incorporates a large LCD Screen for display of menuand results. The results are printed on built-in printer. VT-series incorporatesbreakthrough technology and design that gives accurate and reliable results, againand again. A true four terminal measurement is used to eliminate the need for leadresistance compensation.

The Hot Contact Resistance Tester is purpose-built to evaluate the thermal resistance of materials such as leather, rubber, and polymer outsoles when exposed to high temperatures. Featuring a high-precision copper contact head with a standardized surface area, this unit delivers consistent and repeatable results in accordance with international safety standards.

The tester allows for adjustable dwell time and temperature settings, with digital displays providing real-time monitoring of both variables. A standard 200g weight ensures uniform pressure during contact, enhancing test consistency. The robust design and precise control features make this tester ideal for safety compliance and material research applications.

Key Features

• Copper contact head with precise surface dimensions
• Digital displays for accurate monitoring of temperature and time
• Adjustable dwell time for versatile testing scenarios
• Conforms to multiple international testing standards
• Consistent 200g weight for uniform pressure
• Operates reliably on 220V AC power supply

The Rotary Abrasion Tester is a precision laboratory instrument designed to evaluate the abrasion resistance and durability of materials such as leather, textiles, rubber, coatings, plastics, and laminates. The tester operates on a rotary motion principle, where the specimen is subjected to continuous friction against an abrasive surface, simulating real-life wear and tear. Widely used in quality control, R&D laboratories, and material testing centers, it ensures products meet international standards for abrasion and surface durability.

Key Features

• Rotary Abrasion Mechanism – Provides uniform wear simulation through controlled rotation.

• Adjustable Load & Speed – Customizable parameters for different materials and test standards.

• Digital Cycle Counter – Real-time monitoring of test cycles.

• Durable Construction – Sturdy frame and abrasion-resistant components for long-term use.

• Standard Compliance – Conforms to ISO, ASTM, and BIS standards for abrasion testing.

• Versatile Applications – Suitable for leather, textiles, plastics, coatings, laminates, and composites.

• Easy Specimen Mounting – Quick and secure placement of test samples.

The MIT Folding Endurance Tester is a precision testing device used to measure the folding endurance of various sheet materials, including paper, paperboard, and plastic films. It determines the number of folds a sample can endure under controlled conditions until it breaks, offering valuable insights into the material's durability and flexibility.

Engineered with standard-grade materials for long-lasting performance, the tester features a digital display that ensures clear visibility of test results. It is designed to operate on both single and three-phase AC power, offering flexible integration into different lab or industrial environments.

Key Features

• Digital display for accurate and easy result monitoring
• Supports both single and three-phase operation
• Consumes minimal power (3A at 220V)
• Built with durable, standard-grade components
• Ideal for continuous, high-precision folding tests
