coverstory

New Personal Electronic Dosimeter (PED)

Tracerco will soon be launching a new extended family of PEDs.

The PED family has been designed to be easy to use and understand.  Everything on the PED’s has been designed with the user in mind, from the simple display, to the one button operation, and easy to use software.

The products available in this Personal range are;

  • theprobeapril15sTracerco PED – ‘IS’     

The original T404 PED.  Intrinsically safe”, robust and easy to use

  • Tracerco PED – ‘Blue’

The PED Blue, has a 10% weight saving and can be charged with USB connection. With DoseVision™ software, the PED Blue is aimed at first responders, medical and life sciences, nuclear, industrial and in NDT. 

  • Tracerco PED – ‘+’        

The PED+, a personal dosimeter & survey meter in one. Off-body mode measures activity through a live trend graph and logged data can be reviewed using DoseVision. The PED+ has alarm and pop-up message system, which communicates procedures, for example, exclusion zones. PED + also supported by mobile Bluetooth for an overview of up to 7 x PED+ devices (15m radius). Data logged by location via Bluetooth and GPS

Helmut Fischer Launch their NEW SIGMASCOPE® GOLD C,

for testing coins and thin ingots (up to approx. 100 g)

SIGMASCOPE GOLD the probe aoril 15The SIGMASCOPE GOLD C offers 4 unique measurement ranges, technically optimised for authenticity testing of a huge variety of different precious coins and thin ingots.

This new model compliments the existing range including;

SIGMASCOPE GOLD B for testing bullion, 1 oz to 1 kg

For thicker gold bars up to 1 kg. As  measurements are taken from both sides, the bars can be analysed in their full depth so the authenticity of the alloy or fine gold can be verified. Even concealed inclusions of ignoble materials with matching density such as Tungsten can be detected clearly with SIGMASCOPE GOLD.

Foerster – Magnetische Pruefanlagen GmbH, launch their new Magnatest D 3.623, for manual or automatic magnetic-inductive non-destructive material testing

Magnatest D 3.623 the probe aoril 15Features;

  • Processor-controlled testing system for manual or automatic magneto-inductive non-destructive material testing
  • Single coil absolute operation, therefore no comparison coil required; optional adapter for two-coil differential operation
  • Load-independent induction current, therefore constant induction current intensity and constant magnetic field strength during the testing
  • High induction current intensity thus stimulation of higher harmonics and particularly high test sensitivity to the magnetic characteristics of the test material
  • Single frequency or multi-frequency testing, harmonics analysis
  • Simple operator guidance thanks to application-specific function buttons and high resolution TFT colour screen
  • Standardised interfaces for peripheral equipment (keyboard, mouse, printer, network, etc.)

Weather resistance of sealed anodised Coatings

weathercoatingsAluminium is often used for architecturally pleasing building façades and other structures exposed to weathering influences. Lightweight and fairly easy to work, it is also durable and requires little to no maintenance over the long term when effectively protected by an anodised coating. But to ensure the reliability of the corrosion protection, the sealing of the coating must be verified.

Pure aluminium is highly susceptible to corrosion. However, in contrast to iron, it naturally forms a corrosion-inhibiting layer on its surface when it comes into contact with oxygen, which preserves it very well under normal environmental conditions: When this protective oxide layer is scratched away it is quickly replenished upon renewed exposure to oxygen.

Nonetheless, for many applications, especially out-ofdoors, this natural protection does not suffice because even the smallest entrapment of heavy metals can prevent the formation of a seamless oxide layer, allowing corrosion to get in and cause damage.

weather coatings testingIn order to improve on the natural oxide film, an electrolytic passivation process called anodic oxidation, or anodising, is often used. In an acid bath, oxygen released by an electrical current immediately reacts with the aluminum. It forms two oxide layers: a very thin insulating film (barrier layer) directly on the metal and, above that, a thicker, porous layer. Due to its microporous structure, the outer layer is vulnerable to contamination, requiring a post-treatment (hydration) that expands the coating and causes the pore walls to swell and close off at the surface (sealing).

Although the ultimate quality of the sealing depends on a variety of factors including the condition of the oxide layer, the hydration time, the sealing bath temperature, the pH value of the solution, etc., it can be examined simply and non-destructively by measuring the electrical admittance (Y). Using FISCHER’s handheld ANOTEST® YMP30-S instrument, the coating’s admittance can be determined in situ according to standards such as DIN EN ISO12373-5 and ASTM B 457-67. An electronic reference is also available for cross-verification of the instrument.

With the ANOTEST® YMP30-S, the sealing of anodised aluminium can be tested by measuring its electrical admittance. This makes it possible to determine the corrosion resistance of façades and other aluminium components exposed to weathering influences.
