New Ammonia Analyser
Tiger Optics (USA), keeping pace with explosive growth in the High Brightness Light-Emitting Diode market, announce plans to introduce ALOHATM, the world’s first ammonia analyser designed and manufactured exclusively for HB LED-related applications.
Tiger, a leading manufacturer of laser-based trace gas analysers renowned for clean technology, already sells devices to HB-LED makers, tool manufacturers and the gas companies that supply ammonia, the favored source of nitrogen for the production of Gallium nitride (GaN) compound semiconductor wafers, a core component of HB LEDs.
“Since 2004, we’ve sold almost 100 units in ammonia service around the world,” said Lisa Bergson, Tiger Optics’ founder and chief executive. We offer the most exacting and proven specifications in the field. With the surge in demand for HB LEDs, we realised that we could help our customers by designing an instrument tailored to their specific needs. We know that the purer the gas, the brighter the LEDs, and the bigger the margins for LED makers.”

High-brightness LEDs offer brighter, cooler light, with lower power consumption and longer life than traditional fluorescent lamps. Unlike fluorescents, HB LEDs use no mercury. Widely used in mobile appliances, such as cell phones, cameras, and the Apple iPad, HB LEDs are quickly gaining favor in larger devices. Demand is surging for HB LEDs to “backlight” the Liquid Crystal Display (LCD) units of TV screens and computer monitors.
Indeed, “backlight” applications are projected to account for 56 percent of the HB-LED market this year, according to Robert Steele, Director of the Optoelectronics Program with Strategies Unlimited, the market research firm in Mountain View, CA that produces the “Strategies in Light” annual HB-LED conference. Steele, writing for LEDs Magazine in March, projected worldwide HB-LED sales of $8.2 billion this year, up 52 percent from 2009.
With its first-quarter sales, Tiger Optics surpassed its own goals for HB LEDs by 250 per cent and validated the bullish outlook of industry seers. Spurred by such customer demand, Tiger has developed the ALOHA analyser, to deliver the compact footprint, sensitivity, robustness, low cost of maintenance, speed of response, and uninterrupted throughput that the HB-LED market demands and deserves.

When it is Too Cold for Normal Wind Sensors
SYSTEMS EQUIVALENT TO THE EU REFERENCE METHODS ACCORDING TO EN15267
Air Quality Measurement with a Minimum of Costs
You don’t have to spend a fortune on maintenance. Install an Opsis moni- toring system and save operational expenses.
• SO2, NO2 and O3 – Opsis DOAS system is approved.
• PM10 and PM2.5 – Opsis SM200 particulate system is approved.
The Wilh. LAMBRECHT (Germany) presents their new cold-climate wind sensor. The PROFESSIONAL-IX 2.0 is a robust, compact and very reliable wind sensor for the registration of wind direction and speed. The PROFESSIONAL-IX 2.0 is designed for solid operation under extreme climate conditions and is therefore especially suited for the use in wind turbines under cold climate conditions. The integrated 125 W heating of the moving parts allows the sensors to operate in a wide temperature range down to –40°C. The heating is effectively decoupled from the electronics. But when the heating is switched on, the temperature inside the housing will stay high enough for the electronics to work even at –50°C.
Due to the tested Ingress Protection Rating of IP65 and the usage of sea water resistant aluminium for the spray and dust tight housing the sensors are also suitable for offshore applications.

The sensor is available with different output signals like 4…20 mA or 0…10 V without additional signal converters. The electronics for the contact less signal detection, processing, output and heating control are integrated inside the PROFESSIONAL-IX 2.0. The linearised output signals can be customised for special applications.
