KAB SpeedStrobe. Click to go to manufacturers site.

"The KAB SpeedStrobe was designed to replace and improve upon older strobe designs that relied on power line frequency.

We also wanted something that was easier to use and included the ability to actually measure small amounts of error.

Not just a go - no - go - test.

The KAB SpeedStrobe features a quartz locked illuminator with 99.99% accuracy.

And since it is battery operated, it works everywhere. No need for 50 or 60 Hz versions.

The Disc is silk screen printed on durable 20 mil PVC.

Instead of hypnotic bars, the KAB SpeedStrobe features the actual speed numbers.

In use, the desired speed is read directly from the disc. no searching for the right band.

Covers 16.66, 33.33, 45, 70.59 - 90 RPM.

By timing the drift of the display over one minute, accuracy can be measured to 0.03%"

DR FEICKERT Alignment Protractor NG. Click to go to manufacturers site.

"The new Dr. Feickert Alignment Protractor NG (Next Generation) is a precision device that enables you to adjust cartridges and tonearms with an effective length from 8,6 up to 17,7 inches for correct overhang and offset.

The calculation of parameters are carefully carried out according Lofgren, Baerwald and Stevenson equations aiming at reduction of the overall RMS distortion level caused by deviations from the perfect linear tracking position of your cartridge.

The general geometrical correlation of a tracking device based on a fixed pivot point are well known since the fundamental publications of Baerwald and Lofgren back in the first half of the 20th century.

The conclusion of both papers was that such a tracking device must have an angular offset with a defined overhang.

The offset and the overhang vary with the effective length of the tonearm itself.

While tracking the record the stylus matches tangential position in the groove at two points – the inner and outer Null points (linear tracking position)."

5MP USB 2.0 Digital Microscope with Professional Stand. Click to go to manufacturers site.

"A USB microscope with a simple but incredibly useful stand that allows you to make fine adjustments to the vertical height of the microscope and swivel the scope arm around a 360 degree range.

This permits a greater level of viewing accuracy and stability.

The microscope can be easily removed for the stand for situations which demand it.

On either side of the stand there are two metal holders to lock your object in place and a printed ruler to help you get an approximate feel for the length of objects.

The optics built into this microscope are excellent.

The sharpness of texture on magnified objects is incredible to look at you will spend hours searching for things to magnify (check out a full resolution 5MP capture on our website).
Excellent for educational purposes or a myriad of practical applications such as technicians, jewellers, laboratory work, and much more."
