STR Model S – 20 is a low cost digital Table Top instrument for
measurement of d. c. magnetic fields is using Hall Probes. It has two
ranges 20 K Gauss. A built in calibration facility ensures quick check
of calibration. All the controls are mounted on the front panel and
are clearly designed. An attractive plastic cabinet with carrying cum
tilt bracket takes make the instrument light in weight and portable.
LED display gives direct reading with 1 Gauss resolution on the 2k range
and 10 Gauss resolution on the 20 K range. The unit is supplied with
a Calibrated transverse Hall Probe of 50 mmx 1.5mm with the actual sensing
area of 1 sq.mm from the tip.
CIRCUITRY
The control unit consists of a constant generator, an amplifier and
seven segment LED display. A constant current is made to pass through
the Hall probe, which when place in a magnetic field produces a voltage
proportional to the magnetic filed. This voltage is amplifier circuit
and output is read on a digital panel meter calibrated in kilo gauss.

APPLICATIONS:
General purpose instrument for accurate flux density measurement on
magnetic and electromagnetic components such as relays, dc motors, magnets,
loudspeakers, etc. Very useful for on line production testing.
