THE AUTO MAGNETIC SUSCEPTIBILITY BALANCE
The Magnetic Susceptibility Balance - AUTO is a microprocessor controlled, state of the art balance for detecting the magnetic properties of gases, liquids and solids. The improved sensitivity, versatility and overall performance make it ideally suited for new analytical applications in the research laboratory and industrial quality quality control.
Retaining all the advantages of our MK I instrument, the enhanced features of the Magnetic Susceptibility Balance AUTO are described:
TRUE PORTABILITY
This balance weighs just under 2.2 kg. and comes complete with rechargeable battery which allows up to 8 hours ofoperation 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.
EFFICIENCY AND SIMPLICITY THROUGH MICROPROCESSOR CONTROL
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 or manipulation. By entering the sample weight and length (internal sensors detect the diameter of sample tube) Mass susceptibility can be read directly from the display.The instrument automatically zeroes when the sample tube is not in position, so it is always ready for use. An auto tare facility can be implemented by simply pressing the Tare key with a blank tube in the sample position.
DIVERSITY AND VERSATILITY
The balance comes equipped with the following sample tubes to accomodate a wide range of analytical applications: 2 normal sample tubes (0.400 cm. OD x 0.324 cm. ID) Small bore tubes (ID options 0.100 and 0.200 cm.) and The instrument comes with sample tube holder and manual. |

HIGH SENSITIVITY AND FLEXIBLE INPUT/OUTPUT AND CONTROL
The Magnetic Susceptibility Balance AUTO can now measure from 0.001 x 10-7 to 1.00 x 10-3 c.g.s. Volume susceptibility units over four operating ranges. This is two orders of magnitude more sensitive than the Mark I, which is itself comparable in sensitivity to most traditional methods. The instrument includes both an RS - 232 computer interface and an analogue output for a chart recorder - particularly useful when using the Magnetic Susceptibility Balance AUTO as a detector.The sample 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 susbtances or reactions.
