Bulb thermometers are good for measuring temperature accurately, but they are harder to use when the goal is to control the temperature. The bimetallic strip thermometer, because it is made of metal, is good at controlling things.The principle behind a bimetallic strip thermometer relies on the fact that different metals expand at different rates as they warm up.he bimetallic strip thermometer, because it is made of metal, is good at controlling things.

Can people get ear mites? A: While it is possible for humans to become infected with ear mites, it is highly unlikely, as most humans are immune to ear mites, according to the ASPCA. Ear mites are eight-legged parasites that feed on the oils and wax present in a cat's or dog's ear.
When separated from their insect prey, itch mites may contact and bite other animals including humans. The mites cannot be seen and the bites are not felt, but leave itchy red marks that can resemble a skin rash. When itch mite populations âexplode,â people and other animals may receive numerous bites. Fortunately, the mites cannot live on humans, do not survive indoors, and are not known to transmit disease.
