Temperature Measurement In-probe sensor (accurate to 0.5 °C) Range 0 °C to +50 °C
Automatic Compensation Conductivity measurements are corrected to the 20°C value.
Environmental Range 0 to 95% relative humidity, 0°C to +50°C for reliable operation

Data Logger Memory Up to 500 readings. Up to 50 files.

Probes

12.7 mm diameter for 60 kHz and 500 kHz. 8 mm probe operates at
500 kHz only. Probes are interchangeable with simple operator re­setting procedure. Replacement probes may be installed by user.

Accessories

Operator Reference Blocks - A range of traceable conductivity
references are available for in-field use. Up to five can be mounted on
an aluminium anodised holding plate.

Measurement of Electrical Conductivity is
an accurate and repeatable method for
checking non-ferrous metals for identity,
grade and material conditions. The
AutoSigma 3000 gives accurate operation
in an easy to use package that is both light
and rugged.

The Instrument

The AutoSigma 3000 is designed for
operator convenience. The lightweight,
battery powered unit is easy to carry and
easy to hold during inspections. A large
character, backlit display makes reading
easy even in low light conditions.

The AutoSigma 3000 has two alternative
operating frequencies. The 500 kHz
frequency allows inspection of thin
materials using the standard probe. The 60
kHz setting is the aerospace industry
standard.

Low power circuitry gives up to 100 hours
of operation from a single set of alkaline
batteries, whilst temperature and lift-off
compensation ensure the accuracy of each
measurement.

Flexibility of operation is also improved
with the AutoSigma 3000 - the user can
exchange probes in the field, without the
need to return the unit to base for probe
matching. This system allows the instant
replacement of damaged probes, and an
easy transfer between the different
diameter probes available.

The AutoSigma 3000 has an in-built data­logger facility, allowing the recording of up
to 500 readings, the unit can also be
connected to a PC for fuller report
generation.

Accurate Measurement Every Time

Applications

The AutoSigma 3000 has many applications within the field of electrical conductivity
testing. It is suitable for:

• Alloy identification and verification

• The verification of heat treatment during manufacture and to detect in-service heat
damage (e.g. in aircraft)

• The detection of changes in material grade

• Metal sorting

• Determination of the density of powder metal parts

• To measure the electrical conductivity of material (wire, bus bars and conductors) during
production and in-service
