Bartington Susceptibility/Temperature System
This system is designed for the measurement of the magnetic susceptibility
of 2.5ml samples over the temperature range -200°C to +900°C.
It is used in the investigation of magnetic mineralogy and grain size and
for the determination of Curie transition temperatures.
The components of the system are:
MS2W - Water cooled sensor with integral electronics and excellent temperature stability.
MS2WF - Furnace for high temperature measurements. Low temperature measurements can be obtained by cooling the specimen in liquid nitrogen and taking measurements during return to the ambient temperature.
MS2WFP - Power supply for the furnace with RS232 serial interface for computer output.
GEOLABSOFT - Software collects and plots susceptibility values over the temperature range of interest.

This water jacketed sensor with integral electronics has a 30mm diameter sample cavity. It can be used in conjunction with the MS2 meter and a non-magnetic type T thermocouple (Cu/Cu-Ni) for measurements on 10 ml cylindrical samples over the temperature range -200°C to room temperature.
A water jacket thermally isolates the electronics from the sample cavity. Measurement sensitivity is 1 x 10^-6 CGS for a 10ml sample; this is reduced by a factor of 4 for a 2.5ml sample.

This furnace is installed inside the cavity of the water jacketed sensor to enable samples to be measured at temperatures to 900°C. The non-inductively wound platinum heating element on a quartz cylinder ensures uniform heating of the sample and insulation reduces the maximum external temperature to around 100°C.
A digital panel meter installed in the base of the furnace displays the sample temperature to a resolution of 1°C when supplied with a signal from the Type S (Pt/Pt-Rh) or Type T (Cu/Cu-Ni) thermocouple. The sample temperature is also available in the form of an analog signal.
A retort stand is provided for easy mounting of the MS2W sensor.

|This unit supplies power to the furnace type MS2WF ensuring highly reproducible sample heating. The sample temperature can be increased or decreased with a linear ramp or maintained at its present level, using manual controls.|

Geolabsoft - PC compatible softwareThis package collects data and plots a graph of susceptibility versus temperature whilst measurements are being taken. It includes a facility for automatic drift correction of data at the end of a measurement sequence.
Data are stored on disc for later examination and can be printed in a graphical or tabular format. For detailed examination, the user can "zoom" in on a particular area of the graph. The software is supplied on a 3½" disc.
