S T O C K TA K E THE AIR UP THERE Kemper has introduced its new air monitoring system AirWatch, able to determine and document the number and weight of nanoparticles and then analyse it with a smartphone, tablet or PC and compare it to limit values. A traffic light display shows the status of air quality of the product that is ideally suited for any workplace in production facilities, warehouses and logistics halls – anywhere where fine dusk is a risk. AirWatch continuously monitors the air quality regardless of the type of workplace. The air monitoring system measures fine dust particles in a radius of up to 30 meters using a laser-powered sensor. An integrated fan draws in ambient air. AirWatch captures particles in the range of 100 nanometers up to 16 micrometers. This area includes fine dust categories. In addition to checking the air quality, AirWatch also monitors the effectiveness of ventilation measures. www.kemper.eu SWITCH TO MULTISTRIKE FOR IMPROVED TUNGSTEN PERFORMANCE Tungsten electrodes are used when arc welding with the Tungsten Inert Gas (TIG) process or plasma welding. It is necessary to grind tungsten electrodes after they have touched the molten weld pool or the filler rod to the tungsten, which is not only time consuming but can be a hazard to health. Recognising both the performance requirement and the risk to health posed by thoriated tungsten electrodes, Huntingdon Fusion Techniques MultiStrike tungsten electrodes not only deliver an increased performance, they also reduce the risk to health. MultiStrike contains a mix of nonradioactive rare earth elements, which dramatically lower the working temperature of the tungsten electrode, making it longer lasting. It can be used for welding aluminium with the AC process as well as steels and alloys with the DC process, which allows the welder to have just one type of tungsten electrode to weld all materials and reduce the amount of stocks and purchasing requisitions. Other tungsten electrodes work at higher temperatures so their oxide additions (mostly radioactive) burn out, or evaporate much faster than those non-radioactive ingredients in MultiStrike, so much so that MultiStrikes give at least 10 times more arc striking capacity of other tungsten electrodes tested under the same conditions. With most tungsten electrodes in use still containing radioactive and carcinogenic 2% thorium oxide, MultiStrike provides the TIG and plasma welder with a safe and superior alternative. www.huntingdonfusion.com JUST QUIETLY, A NEW STRAIN GAUGE AMPLIFIER Futek Advanced Sensor Technology has recently announced the newest addition to their amplifier family - the IAA300. The IAA300 is a differential strain gauge amplifier with an ultra-low noise output. It is field configurable, making it easy to make adjustments on the fly. And with easy to adjust DIP switches the IAA300 saves valuable time and energy. The IAA300 is super-fast with up to 50Khz bandwidth, is made with a stainless steel cover fastened by magnets to an aluminium body, has IP50 protection and weighs a mere 109grams. Highlights include: differential Input/differential output; ultra-Low Noise Output; Upto 50Khz Bandwidth; ±5 or ±10 VDC outputs; selectable bandwidths (DIP switch); external accessible shunt CAL activation; weight – 109 grams; material - stainless steel and aluminium. Futek is represented in Australia and New Zealand by Metromatics. www.metromatics.co.nz
