Audit Series - 105 Thickness Gauges 


Baugh & Weedon Ltd, have been designing and manufacturing Ultrasonic test equipment for over 40 years. During this period a policy of continuous technological development and close observation of user requirements has enabled us to offer an excellent range of thickness gauges for industrial applications.

The Audit Series provides users with an optimum combination of economy, accuracy, robustness and simplicity of operation.

Both Audit 105 and Audit 106 are exceptionally tough, yet well finished instruments. Electronic micro circuitry is housed in a rigid hermetically sealed ABS case, with a front panel membrane ensuring excellent environmental protection.

The standard DT25 probe is specially constructed to withstand the most arduous operating conditions and the roughest of handling. An integral probe lead is connected to the durable stainless steel probe housing via a flexible fitting to reduce the risk of

breakage. The cable is further protected by a covering sheath, and connects to the instrument via a robustly constructed plug.

An alternative DT15 Probe with separate lead is available. The DT1, used with a spring loaded holder, is able to locate accurately on curved surfaces down to a radius of 20mm. 


Audit ultrasonic thickness gauges have found ready applications in a wide variety of industries, including:

+  Road Transport

+  Chemicals & Petrochemicals

+  Warehousing

+  Food Manufacture

+  Railways

+  Shipping

+  Offshore

+  Civil Engineering

+  Process lndustries

+  Defence

+  Aircraft

+  Glass

+  General Engineering

+  LPG and mains gas distribution

+  Mechanical Handling

+  Plastics

+  Mines & Quarries

+  Engineering

+  lnsurance

+  Water Distribution

+  Fabrication

+  Paper

+  Cement

+  Forges & Foundries

+  Tube-making 

The Audit 105 is pre-calibrated to measure mild steel and offers the ultimate in ease of operation. Press the ON button, apply couplant (liquid or gel) to the area to be measured, place the probe on the surface, and read the LCD display. And
that’s all - no controls, and no difficult calibration procedures.

A built-in warning display eliminates the risk of spurious readings, and the instrument switches itself off when not in use. As a confidence check, a 6mm test block mounted on the front panel

is always available for reference, to ensure the correct operation of instrument and probe.

The Audit 106 offers the additional facility of ten preset calibration programs for a selection of commonly used engineering materials. Program selection is simply effected by pressing the MAT button. The Audit 106 also features a zero facility.

The Audit 107 allows full Operator calibration either by setting velocity or using testpieces of known thickness, of the material to be measured. This allows greater accuracy of the results. 


Each instrument is supplied with:

2AAalkaline cells, DT25, 5MHz, probe fitted with integral probe lead, Operator Manual, Moulded plastic transit case, Ultrasonic coupling agent in 125 ml container.


DT15, 5MHz, Probe, fitted with subvis connectors, Twin Probe Cable for

use with DT15 Probe, Probe holder to allow use of DT15 Probe on curved surfaces down to a radius of 20mm, DT27 5MHz Side Entry Probe with subvis connectors.

The above is available with the Audit 107 plus:

DT21 high temperature probe ( 150’C intermittent) (3-100 mm), TCE20-2.5 probe, 2.5MHz (3-200mm) for attenuative materials, Probe holder to allow use of DTl5 curved surfaces down to a radius of 20 mm.
