Surface Insulation Resistance Testing
AutoSIR2™
One AutoSIR chassis can hold between 1 to 16 measurement cards and can monitor up to 256 x 2-point test patterns or 78 x 5-point test patterns, or 32 x 9-point test patterns at selectable intervals from minutes to days. Each channel is current limited (1 M Ω), ensuring that dendrites are preserved for failure analysis. The frequent monitoring capability provides a full picture of the electrochemical reactions taking place on a circuit assembly, and provides early trend analysis enabling tests to be curtailed, thus saving considerable test time and money.

Polarization Maintaining Fiber Components
OZ Optics offers a broad range of polarization maintaining components, patchcords, and connectors designed to resolve polarization problems, which are becoming increasingly important in today's higher speed and more complex mesh optical networks. By maintaining the polarization of the signal at its source, our polarization maintaining components minimize polarization mode dispersion and eliminate the effect of polarization dependent loss thereby increasing the quality of the signal that is transmitted throughout the network.

Earth Contact Resistance Tester
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.
