They are small metal probes with a dial on one end. Stick the other end in food and it will read temperature.
Websites such as Grainger sell temperature probes. These probes fit to different temperatures and range in price from $40 to $180 for the high end ones.
Most common use is in Exhaust Gas Temperature probes.
Primarily a thermometer, also temperature probes occasionally (more for controllers of hot plates though)
Probes in a fermenter are used to monitor and control key parameters such as temperature, pH, dissolved oxygen, and agitation speed. These probes provide real-time data that helps ensure optimal conditions for the growth of microorganisms and the production of desired products during fermentation processes.
The recommended annealing temperature for performing thermal cycling in a PCR using TaqMan probes is typically around 60-65 degrees Celsius.
Two examples of probes are spacecraft like Voyager or New Horizons, which are sent to explore outer planets and the edges of our solar system, and scientific instruments like thermometers or pH meters used to measure temperature or acidity levels in various substances.
Between 1983 and 1994, four probes containing temperature and pressure measurement devices and video equipment were lowered into Old Faithful. The probes were lowered as deep as 72 feet (22 m). Temperature measurements of the water at this depth was 244 °F (118 °C), the same as was measured in 1942.
Thermocouple elements are temperature sensors that are useful over a wide range of temperatures. They are used with thermocouple temperature probes, bimetallic devices that are suitable for various temperature sensing applications.
A thermometer is typically used to measure water temperature. Digital thermometers or temperature probes are commonly used for quick and accurate readings.
4 space probes
Space probes would be safer.
Molecular Probes was created in 1975.
