‘Thermometer Guns’ on Coronavirus Front Lines Are ‘Notoriously Not Accurate’

The growing demand for thermometer guns and infrared cameras that can detect fevers has caused shortages across the world, from the center of the outbreak in Wuhan to a small supplier in Texas.

A host of Chinese companies make thermometer guns, which have become more expensive as demand has increased.

Alicn Medical (Shenzhen), a manufacturing in the Chinese city of Shenzhen, makes 2.5 million thermometer guns a year and is one of only a handful in China that can achieve that level of production, said Mo Yingchun, its general manager. Still, raw material costs have surged and many workers can’t get around China’s outbreak containment efforts to show up for their jobs, meaning the company isn’t producing at full capacity.

“Even the governments are fighting for the products among themselves,” Mr. Mo said, noting that priced had climbed to three to five time their usual level. “Local governments want to guarantee their own needs first.”

He said the thermometer are typically used indoors for checking on babies. “The thermometer guns are used only for quick screening and are not as accurate as traditional thermometers,” Mr. Mo said. “It was a small industry and, if it weren’t for the outbreak, it will not be put in the spotlight.”

Thousands of miles from the heart of the outbreak, a small technology supplier in Beaumont, Tex., called Infrared Cameras Inc., has also been feeling the crush of demand. The company makes high-tech imaging equipment as well as infrared thermometers, which cost $25 apiece.

In a normal month, the company sells about 100 infrared cameras, according to its chief executive, Gary Strahan. Since January, the company has sold more than 1,000, supplying schools, cruise ships, factories, offices, hospitals and theaters in countries like China and South Korea.
