Thermal imagers help spot SARS carriers

Land Instruments International product story

A new thermal imaging system gives consistent results when checking for elevated temperatures indicating the possible presence of the deadly SARS virus.
Recent trials and demonstrations have shown that the special new thermal imaging system developed by Land Instruments International gives the most consistent results when checking for elevated temperatures indicating the possible presence of the deadly SARS virus.
Land's new human body temperature monitoring system provided the most accurate and stable temperature readings when compared with rival products during trials by Singapore's National Laboratory.
The results persuaded the engineering department at the island's Changi Airport to purchase ten systems, with the prospect for further orders to equip all of the airport's surveillance points.
The Land system uses a miniature online imaging camera, which activates an audible alarm if anyone passes through its field of view with a body temperature above 38C, one of the key symptoms of SARS.
People identified in this way are then given further tests to establish whether they have the disease.
Systems have also been sold in Saudi Arabia, Dubai and Taiwan, and Land's subsidiaries and distributors are working at full stretch to demonstrate the accuracy of the instrument to potential buyers throughout the rest of the Middle and Far East.
The human body temperature monitoring system is a further refinement of the technology behind Land's newly launched FTI Mv and Mini miniaturised online thermal imagers, which offer high performance and ruggedness at an affordable price.
The FTI Mv is less than 250cm3 in size and weighs just 1.3kg.
Their exceptional level of accuracy is due to the use of a reference temperature calibration source, a unique technique that is in the process of being patented.
As well as detecting the possible presence of SARS, they have other medical and veterinary applications such as displaying the temperature distribution patterns typical of conditions such as poor circulation, vibration white finger, internal bruising and soft tissue damage.
The imagers provide real-time image display and image capture, and can be controlled remotely from a PC using the dedicated image processing software, which includes a powerful range of functions, display options and alarm outputs.
