Why WR-3


Cable Free

Get rid of traditional cable-type anemometer. Avoid possible risks from machine operation. Scarlet WR-3 anemometer gives users a wireless wind monitoring solution.


Long Life

4-year battery life of wind speed sensor in all weather conditions. The sensor is designed to use in rigid environments such as dessert, ocean and mountains.


Stay Alert

Never worries about high wind. Develop a safer working environment. WR-3 Anemometer sends automatic high-volume alarms based on user settings.

Wireless Sensor

WR-3 adopts 433/868/900 MHz wireless technology to ensure better performance for barrier penetration and achieving long range transmission. The sensors start sending data when wind cups revolve. The sensor will go to sleep mode when wind cups stop revolving for more than 6 hours. Data transmit rate: every 2 seconds.

The ultra-long 400 meter transmission distance makes WR-3 a perfect gadget to help you monitor wind speed on crane and prevent from high wind risks.

Handheld Receiver

Large LCD display shows digital wind speed, temperature and beaufort chart clearly. Anti-slip rubber on two slides helps users hold the receiver in place during work. User-friendly interface and simple button design allows you to operate the device easily with only one hand.

When the wind reaches a certain speed, an alarm will be triggered, and it will continue as long as high wind is detected. The alarm buzzer located on top of the receiver can effectively warn users at the level of 90 dB.

Low Power Consumption

We use innovative low-power consumption wirless technology on WR-3. The battery power consumption is only 20-30 uA in normal condition and 35 mA peak current during data transmission. 3.6V Lithium battery with 2400 mAh capacity can run the sensor for 4 years.

4-year long battery life reduces the maintenance cost significantly. Low battery indicatior on the display monitor will show up when battery capacity is lowered than 10%.

Weather extremes worsening - United Nations

Heat waves links to global warming 

Reuters Oslo – The world suffered unprecedented climate extremes in the decade to 2010, from heatwaves in Europe and droughts in Australia to floods in Pakistan, against a backdrop of global warming, a United Nations report said on Wednesday.


Every year of the decade except 2008 was among the 10 warmest since records began in the 1850s, with 2010 the hottest, according to the study by the World Meteorological Organisation (WMO). The number of daily heat records far outstripped lows.


It said many extremes could be explained by natural variations – freak storms and droughts have happened throughout history – but that rising emissions of man-made greenhouse gases also played a role.


"Rising concentrations of heat-trapping greenhouse gases are changing our climate, with far-reaching implications for our environment and our oceans, which are absorbing both carbon dioxide and heat," WMO Secretary-General Michel Jarraud said in a statement.


The study said damaging extremes included Hurricane Katrina in the United States in 2005, Cyclone Nargis in Myanmar in 2008, floods in Pakistan in 2010, droughts in the Amazon basin, Australia and East Africa and a retreat of Arctic sea ice.


Deaths from extreme events totalled 370 000 people, up 20% from the 1990s, the Geneva-based WMO said, though the world population also rose sharply over the period, from 5.3 billion in 1990 to 6.9 billion in 2010.


The jump in the death toll was caused mainly by a heatwave in Europe in 2003 which killed 66 000 and a heatwave in Russia in 2010 in which 55 000 people died.


However, casualties from storms and droughts fell, partly because of better preparedness for disasters.


The study said that 44% of nations recorded the highest daily maximum temperature of the past half-century in the decade 2001 to 2010 but only 11% reported a new low.


It also said that the decade "continued an extended period of accelerating global warming" with average decadal temperatures 0.21°C warmer than 1991 to 2000, which was in turn 0.14°C warmer than 1981 to 1990.

Other reports have found that the rate of temperature rises has slowed this century.


"Global mean surface temperatures have not increased strongly since 1998" despite rising greenhouse gas emissions, according to a draft report by the UN's panel of climate scientists due for release in September.


Some experts say the apparent rise from the 1990s is magnified because a volcanic eruption in the Philippines in 1991 dimmed sunlight and cut temperatures.


The WMO also said it was hard to link any individual extreme events to climate change rather than to natural variability.


However, warmer air can hold more moisture, raising risks of downpours – the study said that 2010 was the wettest year since records began. And sea levels have risen about 20cm in the past century, increasing risks of storm surges.


One 2004 study, for instance, said that climate change had at least doubled the risks of the European heatwave in 2003.


Peter Stott of the UK Met Office who led that study said scientists were now trying to see if there was a human fingerprint behind other extremes in 2012, such as Superstorm Sandy or drought in Australia.

"You can't just take a record-breaking event and say 'that's climate change'," he said.
