The laboratory
is accredited to the ISO 9001-2000.
All
the Reference Standards are regularly calibrated
in-house using the Reciprocity/ Trimetric
method and regularly certified to National Standards.
This is carried out at various times throughout the
year to compensate for water temperature variations.
All
uncertainty calculations are performed by the laboratory’s
bespoke software for each discreet frequency.
The
laboratory is capable of performing the
following measurements:
 Complex
Impedance / Admittance.
Fully automated test presenting Polar, Cartesian and Numerical
formats.
Beam
Pattern.
In either Transmit or Receive mode, automatic
indication of –3dB, –10dB and
sidelobe levels.
Sound
Pressure Levels.
Fully
automated Receive and Transmit Sensitivity and Source Level Measurements,
presenting Linear, Log and Numerical formats.
Phase
and Time.
For sensors and / or systems where bearing and time
accuracies are required.
Simulated
Depth Measurements.
A submersible GRP pressure pot designed to simulate acoustic performance
and calibration measurements down to depths of 650 metres.
