What makes a non-contact thermometer suitable for clinical use?
Any electronic thermometer that gets put onto the market has to comply with a standard known as the ASTM E1965. The standard predicates that devices must be accurate within a tolerance of 0.2 degrees Celcius. So, therefore, anybody who wants to find a properly compliant thermometer should ensure when they look at the specifications of that device, that ASTM E1965 is mentioned and the product accuracy is actually stated. That enables a thermometer to get at CE mark and without a CE mark it should not be on the market for clinical use.
