AC/DC fwbell gaussmeter model #9903, teslameter, 18" transverse probe, F.W.bell

Description

The SERIES-9900 gaussmeter represents the latest developments in the science of measuring magnetic flux density using the Hall effect. The unit is available in three configurations capable of processing a single channel (Model 9901), two channels (Model 9902) or three channels (Model 9903) of magnetic field information. Either steady-state (dc) or alternating (ac) fields can be measured. When matched with the appropriate F.W. Bell fourthgeneration Hall generator probe, fields as low as 10 pG (0.0011.1T) or as high as 2.9999 MG (299.99 T), at frequencies up to 50 kHz, can be measured with extreme accuracy and 4-3/4 digit resolution. The SERIES-9900 features PEAK HOLD, AUTORANGING, CLASSIFIER and RELATIVE operation, auto ZEROing, GAUSS or TESLA readout, digital and bargraph representation, diagnostics and remote operation with an IEEE-488 (GPIB) instrumentation bus and an RS-232 communications port. All information is displayed on an illuminated graphics liquid crystal display (LCD). The gaussmeter employs a menu-driven format to allow the user to program all aspects of gaussmeter operation with ease and speed. Each gaussmeter channel is completely and independently programmable.

T-99-284 is a 1X probe. I’ve attached its drawing. The drawing says the cable is only good for 75°C, but I’m pretty sure the cable itself (not connectors) will go to 105°C. The probe body may be only good for 100°C.
It will work on any 9500, 9900, 9550 or 9950 meter.
. Probe is similar to a Model HTF99-0618 (item no. 129944)
also it has more features:
A. Stem has a brass nose plug.
B. Hall Generator /Stem is rated from 0
