Sapphire (Al2O3) is one of the hardest minerals and optical materials available for use in the range from UV up to 5µm. Sapphire is birefringent and if its use is for critical optical application then the crystal might have to be cut along the zero degree plane, or C-Cut. Random cut is usually cut along a plane that is 60° off-axis as the growth in this direction is the easiest to grow. Random cut is anything that is not the C-Cut angle. Sapphire can fluoresce depending upon the concentration of other minerals within the lattice, for example Iron (Fe) or Chromium (Cr). Clear Sapphire might fluoresce orange when illuminated by UV light if impurities are in the crystal. Fluorescent free Sapphire has to be grown from 'pure' feedstock and seed and in an environment that cannot place impurities into the lattice. Click PDF link to read more …...

Rotafix Aquachem is a solvent-free coating used a membrane for tanking, waterproofing, gas barrier and as a high-performance floor coating. Rotafix Aquachem is a 2-part liquid epoxy that can be applied as a floor finish. Combining aggregates with the top coat creates a skid resistant surface. Adding flakes to the top coat will give a decorative finish. It has been used extensively in food preparation areas and medical environments as it is easy to clean, resistant to chemical cleaners and resistant to the formation of mould. Rotafix Aquachem can be used as a liquid applied damp proof membrane. The liquid membrane can be applied to prevent moisture ingress both positively and negatively. So if it is applied to the outside of a wall, water will not penetrate, equally if is applied internally then moisture penetrating the substrate will equally not penetrate. The average bond strength of Aquachem is 4N/mm2 , it would require a head of water of 600m to force the Aquachem to break away.

Preparation is key when it comes to SF6 gas analysis. Ensuring the analyser is within calibration is fundamental to safe operation, compliant measurement and accurate testing. Our Verify NIST traceable verification gases can prove the instrument is in specification and valid for use in accordance with ISO9001 requirements for controlled measurement equipment. EMT SF6 gas verification products utilised during operation provide continued assurance that the analyser is performing as it should be, that the measurements shown are accurate, and that these are in line with the measurement values and tolerances of the supplied gas.

Utilities personnel working on Gas Insulated Switchgear are in danger from exposure to SF6 gas leaks. Colourless and odourless, SF6 can accumulate undetected, presenting serious health and environmental risk. The EMT GasSafe Gas Leak Detection System offers a feature packed solution to monitoring real time gas leaks from electrical equipment or potential other unsafe gaseous emissions. Our gas safety system provides rapid detection, immediate response and early warning in the event of gas leaks or an unsafe working environment, ensuring personnel safety and asset protection. Ideal for traditional SF6 and new SF6 alternative gas installations. Provides an intelligent and comprehensive solution to your SF6 F-Gas leak detection requirements. Measurement of over 400 different gases and vapours from ppm to %Vol. Easily add or remove sensors and accessories as your system needs grow with up to 128 detectors on a single control panel.

With any filling device, a range of accessories can help produce a more efficient fill during maintenance tasks. EMT can supply a range of heated blankets and regulators to ensure if manually filling, the chances of a line freeze are reduced. Typically 20-25% of SF6 is wasted due to temperatures and pressures keeping the SF6 liquified. Our cylinder heater blankets evaporate the gas, increasing the efficiency of the cylinder, to ensure the maximum amount of SF6 can be recovered. This amounts to significant savings on maintenance costs.
