The Epoch 1000 Series consists of three
instrument configuration levels to suit many
inspection needs – Epoch 1000, Epoch
1000iR, and Epoch 1000i. The Epoch 1000
is an advanced ultrasonic flaw detector
that can be upgraded with phased array
imaging.
The Epoch 1000iR provides the same
ultrasonic flaw detection as the Epoch 1000,
with the benefit of upgrading to phased array
with simple remote activation. The Epoch
1000i comes standard with phased array
imaging in addition to the ultrasonic flaw
detection capabilities of the Epoch 1000.
All Epoch 1000 Series instruments feature
a new horizontal case style with sunlight-
readable full VGA display, knob and
arrow keys for parameter adjustment and
navigation, and full EN12668-1 compliance.
Designed to meet IP66 environmental rating
and tested for shock, vibration, explosive
atmosphere and wide temperature ranges,
the instruments can withstand operation in
harsh inspection conditions.
The Epoch 1000i incorporates phased
array imaging capabilities to enhance
conventional single-channel inspections.
This advancement in inspection
capability allows greater
probability of flaw detection,
better visualisation of areas of
interest, and increases inspection
efficiency by allowing simultaneous
inspection of multiple focal laws
and various angles in a single scan,
eliminating the need for multiple
probes and/or wedges. This
permits operators to perform code-
compliant inspections according to
conventional ultrasonic standards
with the advantages of phased
array imaging.
Available with a standard 16:16
probe element configuration,
the Epoch 1000i offers many flaw sizing
features to aid non-destructive inspections.
It comes standard with A-scan and S-scan
(sector scan) views, as well as reference
and sizing cursors for improved flaw size
evaluation. The Epoch 1000i also provides
DAC/TVG capabilities for every focal law,
allowing flaw characterisation of a selected
A-scan based on an acquired DAC curve.
The Epoch series also boasts a portfolio of
standard and optional visualisation features
to aid inspection. These include SureView™,
which mimics the responsiveness of an
analogue instrument CRT display, and
adjustable video filtering in phased array
mode for image smoothing. Combined
with other features, these visualisation
capabilities provide enhanced interpretation
of indications.
