The word comes from the Greek words meaning "heat" (thermo) and "to measure" (meter). A thermometer is comprised of two parts: the temperature sensor, which physically changes in response to changing heat levels, and a measuring device, which puts the physical change into the context of one of several accepted thermal measurement scales. History: Though early thermometers had appeared as early as the 11th century, it wasn't until the invention of the sealed thermometer that the devices began to take on a semblance of accuracy. Because early thermometers were not sealed, they were sensitive to air pressure as well as temperature. It wasn't until the around the 16th century that sealed thermometers were developed, and a measurement scale applied to the implement. The first universal system of thermal measurement was developed by Daniel Gabriel Fahrenheit in 1724, using the melting point of ice and the boiling point of water as references. Anders Celsius proposed the Celsius scale in 1742, which assigned one hundred degrees between the same two points used by Fahrenheit (melting point of ice and boiling point of water). Today, there are as many different types of thermometers as there are private and commercial uses for the measuring of thermal activity. Considerations: All thermometers register a physical change in response to a change in thermal activity. In the case of mechanical thermometers, the change is seen in the movement of solid objects that exert force on one another. Other thermometers can sense changes in, among other things, radiation, electrical activity, or liquid crystals. There are two types of thermometers: primary and secondary thermometers. Primary thermometers rely on the measurement of matter that is known so well that temperature can be calculated to an exact degree, for example, the voltage or current of an electrical resistor, or the angular anisotropy of gamma ray emission of certain radioactive nuclei in a magnetic field. Secondary thermometers are cheaper, more sensitive and more convenient to use, as so are more widely used. However, a secondary thermometer must be calibrated against a primary thermometer at least once before it can be used reliably. Types: There are many different thermometer types for many different private and commercial applications. Some of the most common types include: Alcohol thermometer: an alternative to the common mercury-in-glass thermometer. The main advantage is the safety of the liquid in case of breakage, but it's upper sensitivity range is only 78 degrees Celsius. Bi-metalic thermometer: a device used to convert a change in temperature into mechanical movement along a scale. Instead of a chemical change, such as the expansion of a liquid in an alcohol thermometer, a mechanical change is registered. Infrared thermometer: a device that measures blackbody radiation emitted from objects. The object's temperature can be determined by knowing the amount of energy an object gives off in conjunction with its emissivity. Electrical thermometer: a device that measures the predictable changes in electrical resistance in some materials. Liquid crystal thermometer: a thermometer that utilizes thermochromic crystals which change color in response to temperature changes. These crystals display the mechanical properties of liquid, but look as if they are a single crystal. Liquid crystal thermometers can detect temperature changes down to a tenth of a degree centigrade. Warning: Though rarely used since the advent of digital and mechanical thermometers, use care when handling a mercury-in-glass thermometer, as the mercury is dangerous. When measuring the temperature of the human body using any insertion thermometer, make sure to sterilize the thermometer before use. Inserting an unsterilized thermometer into the body could result in infection. Also, use care when inserting the thermometer into the body. When using a meat thermometer, sterilize the thermometer after each use to avoid food poisoning and infection upon subsequent use. Expert Insight: The traditional method calibrating a secondary liquid based thermometer was to first immerse the sensing bulb in a mixture of ice and water and mark the point where water typically freezes. Next, the thermometer would be immersed in a steam bath at one standard atmosphere (101.325 kPa ) to determine the point at which water boils. The distance was then divided between these marks according to the temperature scale being used. Meat thermometers aren't the only type of thermometer used in the processing of food. Candy thermometers, or sugar thermometers, are used to measure the temperature of cooking sugar solutions. Like the meat thermometer, there are several different kinds of candy thermometer, the main difference being that candy thermometers Package Included: * 1 x Indoor Thermometer & Hygrometer TH123

Great bang for the buck!. I've this Indoor Humidity Thermometer for a couple years now and it continues to work perfectly. Great bang for the buck!translate

Pretty good product. It's hard to know if the readings are precise but they are pretty close. It gives you a good estimate of humidity which was my concern. After buying it I installed a built-in humidifier for my furnace and it registered the humidity quite close to the control pad for the humidifier. Good enough value for the price. The outside temperature feature is pretty accurate also.translate

Very nice!. I love this Accurate Humidity Thermometer (well, 2 guages). It was easy to set up and I have the main unit in my living room, and the 2nd in my bedroom. It's easy to see what the humidity levels are on the 2 floors I have the units. It's pretty accurate as well. The temperature is almost spot on to what my thermostat reading says and I like the fact I can see if I need to tune down the humidifier upstairs if it's getting too high in humidity. Honeywell doesn't disappoint. Great product!translate

Nicely Done. It seemed to take 3-4 hours right out of the box to start giving the exact indoor/outdoor readings. It works very well and is quite accurate but needs to be close to the house if the temperature readout device needs to be placed where more than one wall is between device and sending unit.translate

Great Accurate Humidity Thermometer. Great product and it arrived very quickly. No complaints. Straight forward product and straight forward transaction. Thank you! Would buy from this seller again.translate

Easy to See and Use. This Indoor Humidity Thermometer has a sensor built in and comes with an additional remote sensor. I bought two additional remote sensors, so now I can tell the temp and humidity on two floors, in the garage and outside, all wirelessly. The numbers are big and the interface is as simple as it gets. I haven't used it to track peak and trough, so I'm not sure how that works, but it would be nice if it had a built in clock to stamp those data with.translate

No complaints. No complaints, quick processing and shipping. Cheap and quality goods. Product as described. Don’t expect a polite and friendly customer rep on phone. But usually u will not get a chance to complain. At the end, good shopping here.translate
