  • Millivolt Drop Tester

    SCR ELEKTRONIKS

    The SCR ELEKTRONIKS Millivolt Drop Tester is an industry acclaimed product. MVDT has a specially built constant current source (current generator) up to 400A (depending on model) and a dedicated PLC to store test parameters (in automatic models), perform test procedure, make the millivolt drop & junction resistance measurements and store test results, that can be retrieved later or downloaded to PC. PC based TestWare can display the test results & export those to Office, HTML, Printer or PDF. The manual models consist of the constant current source, digital ammeter and a digital millivolt meter with 3 ranges.

  • SEA CLIP™ Sensor & Aqua MER™ Meter

    The Swain Meter Company

    The SEA CLIP™ by Swain Meter is a high-quality, hydraulically actuated clamp-on DC ammeter for ROV. It is useful for measuring DC currents in subsea cables, cathodic protection systems, and subsea pipes up to 4” in diameter. The SEA CLIP™ can be used with an optional 200-foot cable to a topside meter, or in concert with the Aqua MER™ subsea meter at depths up to 6900 feet of seawater.The Aqua MER™ ROV meter is based on Swain’s proven MER2™ technology, specially adapted to the demanding requirements of the subsea environment and updated to provide RS-485 communication over twisted pair, or fiber optic data transmission protocols.

  • Earth Contact Resistance Tester

    SCR ELEKTRONIKS

    SCR ELEKTRONIKS have developed an equipment namely Earth Contact Resistance Tester to test the appliance. To ensure the safety of operator it is essential that the Earth path (connection) should offer minimum impedance to by pass short circuit Current to Earth. This is ensured by measuring Resistance of the Earth path by passing heavy Current say 25 A. The Earth Contact Resistance Tester essentially comprises of a Variable Current source with digital Ammeter to measure the Current supplied. The Voltage drop across the Earth path is measured with a digital Voltmeter. Optionally for a particular Current (25 A) the meter can be calibrated in terms of Resistance. A timer is provided to switch off the Current after the Set Time.
