MAGNAFLUX ELECTRONIC INSTRUMENTATION
PORTABLE EDDY CURRENT INSTRUMENT
HAND HELD SCANNER FOR DETECTION OF FLAWS IN FASTNER BOLTS
Description and features as described in the Magnaflux HT-100 manual,
"The Model HT-100 Automatic Hole Scanner system is a compact, portable instrument widely used for locating surface and near-surface discontinuities on the interior of fastener holes in metal parts and assemblies. The HT-100 is most commonly used for the detection of cracks in fastener holes in high stress areas in aluminum parts and structures, but can also be used on other materials such as titanium or steel. The instument can also be a valuable tool for crack growth studies on in-service aircraft or other structural members during fatigue testing. The HT-100 is easy to calibrate and set up by following a straightforward step by step procedure. A simple adjustment of the depth of scan is made by turning a thumbwheel control at the top of the scanner while viewing the actual setting through a clear plastic window. The scanner, able to be held comfortably in one hand, is controlled simply by thumb operation of the rocker switch. Scanning and recording upon hole entry is accomplished by setting the switch in the forward position. When the preset depth is reached, both probe drive and chart advance will stop. The probe may then be removed from the hole or the scanner switch set to the reverse position to inspect and record as the probe exits the hole.

Offered is a Magnaflux HT-100.
This is an Untested instument.
This instrument powers-up. When plugged in Scanner accepts all probes and system's RPM adjustment functions scanner speed good in forward and reverse. The indicator needle moves smoothly, has clear clean plastic viewing window, all numbers/letters are well defined and easy to read. When unit placed on test needle moves across to right side of meter. Chart recorder is in good operating condition. When turned on the recorder immediately began recording and will operate in a faster mode if selected. Stylus writing is clearly defined and easily to read. (paper already loaded inside and (1) new paper roll provided)
All cables and connections are in good condition. Scanner/cables attach/connect easily. All dials, switches, buttons and screws turn smoothly and/or function snappy. The red plastic "Output Terminal" is missing. The terminal is fine and Oscope/probe will attach with no problem, terminal fastner is still there just the plastic covering to the fastner is missing.
Case opens/closes properly and the two outside twist locks function well. Lid lever secures inner lid closed and whole lid is removable. Foam removed from the inner lid, the foam was old, lid cleaned up fine without reisdue and can now hold all the equipment.
The HT-100 instument's overall condition shows minor wear.
The scanner shows some cosmetic scratches and paint wear.
Includes a bundle of transducers, probes:
(18) Probes - all fit scanner and are in good condition.
(9) Transducers included, all in good coindition and fit probe/scanner.
There are (5) cables shown in the photos. I had to pull one of the cables from the lot as it was mixed into this set and photographed prior to being removed and added to the other soon to be listed MagnfluxHT-100 set available for purchase.
