OPTIONS AND ACCESSORIES
5.0 GENERAL
This chapter provides details on the Lake Shore 7800 Series Hysteresisgraph System models, options. and
accessories. Model numbers are detailed in Paragraph 5.1 and options and accessories in Paragraph 5.2.
5.1 MODELS
The list of Lake Shore 7800 Series Model Numbers is provided as follows.
Model Description of 7800 Series
7804
The Model 7804 offers field strengths to 20.4 kG (2 T) in an operating air gap of 12.7 mm
(0.5 in.) when the 100 mm (4 in.) vertical electromagnet is configured with 51 mm (2 in.) iron
pole caps. The Model 7804 is ideal for measurement of low energy materials and high energy
materials with moderate magnetic lengths.
Electromagnet: Model EM4-HV-V, 100 mm (4 in.) H-frame, vertical or horizontal orientation.
Power Supply: Model 662, ±70 A/±35 V, 2.4 kW.
7807
The Model 7807 provides field strengths to 25.2 kG (2.5 T) in an operating air gap of 12.7 mm
(0.5 in.) when the 175 mm (7 in.) vertical electromagnet is configured with 76.2 mm (3 in.) iron
pole caps. The Model 7807 is suitable for measurement of high energy samples and for larger
lower energy samples that exceed the capability of the Model 7804.
Electromagnet: Model EM7-HV-V, 175 mm (7 in.) H-frame, vertical or horizontal orientation.
Power Supply: Standard: Model 662, ±70 A/±35 V, 2.4 kW; Optional: Model 665, ±100 A/
±50 V, 5.0 kW.
7810
The Model 7810 provides field strengths to 30 kG (3 T) in an operating air gap of 10 mm
(0.4 in.) when the 250 mm (10 in.) vertical electromagnet is configured with 100 mm (4 in.) iron
pole caps. The Model 7810 offers the highest magnetic fields and the highest uniform working
areas of the 7800 Series Hysteresisgraph System. The Model 7810 is suitable for measurement
of any type of permanent magnet material where large samples and high magnetic fields are
required.
Electromagnet: Model EM10-HV-V, 250 mm (10 in.) H-frame, vertical or horizontal orientation.
Power Supply: Standard: Model 665, ±100 A/±50 V, 5.0 kW; Optional: Model 668, ±135 A/
±65 V, 5.0 kW.
