The TH809 personal ear thermometer provides accurate and rapid temperature readings from the ear within seconds. The ear thermometer is specially designed with safety in mind and is simple to use (temperatures can be taken whilst the patient is asleep). The unit incorporates replaceable probe covers to avoid cross contamination. The ear thermometer measures the temperature of the infrared heat given by the eardrum and surrounding tissues and converts this temperature into an oral equivalent temperature. Unlike an oral thermometer the ear thermometer is unaffected by talking, eating or drinking. Each TH809 personal ear thermometer is supplied complete with 20 probe covers, replacements held in stock.
