The AUTO balance weighs just under 2.2 kg. and comes complete with rechargeable battery which allows up to 8 hours of operation away from a mains power supply.
Supplied in its own robust carrying case the instrument can be fully operational in minutes after arrival at the analysis site. A travel clamp, external to the instrument and easy to apply, and an adjustable level control are the only setting-up procedures required.
The Auto is most suited for materials research and development and quality control measurements where reproducibility and documentation of results are essential.

• In the AUTO the 8751 microprocessor has the balance calibration constant entered during the manufacture. The digital display of the measurement is directly converted to Volume Susceptibility in c.g.s. units without need for calculation nor manipulation. By entering the sample weight and length in the separate keypad (internal sensors detect the diameter of sample tube) can be read directly from the display.
• The Auto automatically zeroes when the sample tube holder is empty. An empty sample tube can be tared, and the value automatically subtracted from subsequent sample measurements. The Auto reads in magnetic susceptibility (mass or volume) units directly without requiring manual calculation.
• The AUTO can measure values from 0.000 x to 1.999 in four ranges, namely 10-7 , x 10-6 , x 10-5 , x 10-4 c.g.s. units. This is two orders of magnitude more sensitive than the MKI, which is itself comparable in sensitivity to most traditional methods.
• The instrument includes both an RS232 computer interface and an analogue output for a chart recorder - particularly useful when using the MSB - AUTO as detector.
• The detector unit is separated from the read-out and controls which are housed in a hand-held unit. The operator can remain away from the sample when measuring hazardous substances or reactions.
