for any combination of longitudinal and transverse flaw and thickness detection. Information will also be available on the Rotoflux ® flux leakage system for inspecting pipe up to 16" (406mm) diameter, to meet API and other specifications. The new MultiMac includes up to eight test channels, and a wide selection of test parameters and special circuits to enhance signal-to-noise ratio. Building on the successful Echohunter ® software graphics, the instrument’s test screen displays one channel, and the multi-screen provides a simultaneous display of one to eight channels. The test screen provides all the information needed to set up and operate MultiMac. Both screens display simultaneous polar and linear modes and all test parameters, including thresholds. Each channel on the MultiMac can be individually configured with different frequencies and different channel modes. For example, ‘differential’ mode is used to detect short weld-line defects, while ‘absolute’ mode is appropriate for long, continuous surface flaws and open welds. A choice of three thresholds per channel – all phase, sector or chord – can be mapped

Magnetic Analysis Corp will exhibit the new MultiMac™ eddy current tester at its stand at Tube 2008. The Windows ® based multi- mode MultiMac operates with encircling/ sector test coils to detect short surface defects, and/or with rotary test probes to detect long, seam type surface defects. The new multi-mode capability incorporates the best features of MAC’s individual encircling coil and rotary probe instruments in one unit. FD-4 electronics with rotary transducers will also be exhibited. The FD-4, with up to 32 independent test channels, is suitable MAC’s Echomac ® ultrasonic

to any of eight outputs, independently configurable for time or distance delay and normal reject or latched mode. With these features, MultiMac can be used to test a wide variety of non-magnetic products, or inspect magnetic material by using direct current saturation systems. A special configuration of channels, based on flux leakage phenomenon, provides detection of very small subsurface steel inclusions in copper or aluminium rod. › Magnetic Analysis Corp’s MultiMac eddy current tester
