Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches. 

Temperature sensors are measurement devices that infer temperature by sensing some physical characteristic (i.e. resistance, emf or thermal radiation).

Dial thermometers are bimetal or bi-metallic, liquid or gas-filled, and vapor-tension-based. These devices display temperatures in Fahrenheit, Celsius, or both

Weather instruments are designed to measure one or multiple components of weather including wind speed and direction, rain or snow fall, solar radiation, temperature, pressure and humidity.

Digital thermometers are portable temperature sensing devices that have permanent probes and a digital display

Industrial thermometers are basic bulb style thermometers designed for use in many industrial applications.  Traditional liquid-in-glass design is typically used due to low cost and ease of use

Laboratory thermometers are used to measure temperatures or temperature changes with a high degree of precision.  Traditional liquid-in-glass design offers ease of use and low cost

Noncontact infrared temperature sensors absorb ambient infrared (IR) radiation given off by a heated surface. They are used in applications where direct temperature measurement is not possible.

Metal rod and bar stock are metals and alloys in the form of round bars or rod, square bars, rectangular or flat bars, hexagons, and other bar stock shapes.

Thermal cutoffs and thermal protectors are nonresetting, thermally sensitive devices designed to protect domestic electrical appliances and industrial equipment from fire. They are sometimes described as thermal one-shot fuses.

Thermostats and thermal switches are electro-mechanical on/off switches that are activated by temperature changes. They are typically used to control heating and cooling systems.

Metal wire and strand has a round, flat, or shaped cross section. Products are usually less than 0.375" in diameter.

Humidity measurement instruments test for absolute humidity, relative humidity, or dew point in air.

Metal foils and foil stock are very thin, metal-mill products with a thickness that is usually less than 0.006 in.

Metal strip is narrow, thin metal or alloy stock that is usually 0.187" (3/16 inch, 4.76 mm) or less in thickness and under 24 inches (609.6 mm) in width.
