Thermometers are devices that accurately read the basal temperature of the body. Express Medical Supply carries oral thermometers as well as forehead thermometers. Probe covers should be used along with oral thermometers to prevent cross-contamination. Temple touch thermometers are non-invasive, making them perfect for a baby or young child. Both oral and forehead thermometers provide a digital reading. A medical thermometer is a staple item to include in a first aid kit.
