Thermistor temperature probes sense temperature by using thermistors, devices made of semiconductor materials which exhibit a large change in resistance for a small change in temperature.
Resistive temperature device (RTD) elements are wire windings or other thin-film serpentines that exhibit changes in resistance with changes in temperature. They are usually made of metallic elements or alloys such as copper, nickel, or nickel-iron.

Levels

(216 companies)
Clinometers or inclinometers can indicate the angular variation or inclination from horizontal. Laser levels project a spot or indicator onto a surface that is level with the projecting laser level. Machinist's levels are smaller and provide a higher degree...
Deflectometers and extensometers are used to indicate the deformation of material while it is subjected to stress.

Thermal Profilers

(19 companies)
Thermal profilers are temperature instruments or recorders that provide temperature profiles for furnaces, kilns, or other continuous thermal processes.

Laboratory Thermometers

(130 companies)
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.

Thermocouple Connectors

(34 companies)
Thermocouple connectors are used to transmit temperature readings from a thermocouple (T/C).
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.

Thermistors

(254 companies)
Thermistors are thermally-sensitive devices whose electrical resistance varies with temperature. Unlike RTDs and thermocouples, thermistors do not have standards associated with their resistance vs. temperature characteristics or curves.

Thermowells

(258 companies)
Thermowells are designed to accept numerous types of temperature probes. They are used to easily facilitate the repair of temperature sensing devices without interrupting the process being monitored.

Digital Thermometers

(504 companies)
Digital thermometers are portable temperature sensing devices that have permanent probes and a digital display.

Damage Indicators

(28 companies)
Damage indicators are applied onto or within containers and products to indicate that the device has been exposed to environmental factors that could damage the packaged goods.

Infrared Thermometers

(128 companies)
Infrared Thermometers are non-contact temperature devices that use infrared radiation to infer the temperature of an object.

Thermocouple Elements

(292 companies)
Thermocouple elements are temperature sensors that are useful over a wide range of temperatures. Thermocouples are formed by two dissimilar metals.
Shipping and Handling Labels are preprinted labels that identify proper handling directions and in some cases destination information. These labels may indicate contents of package such as Flamability or Fragile or they may indicate directions for handling.
