Voltage probes are used to measure voltages present on the DUT. To achieve high accuracy, the test instrument and its probe must not significantly affect the voltage being measured. This is accomplished by ensuring that the combination of instrument and probe exhibit a sufficiently high impedance that will not load the DUT.
The tip of the instrument is placed with light pressure of 10-20 grams [1] into the gingival sulcus, which is an area of potential space between a tooth and the surrounding tissue. It is important to keep the periodontal probe parallel to the contours of the root of the tooth and to insert the probe down to the base of the pocket. This results ...

A No. 23 explorer, also known as a 'sickle probe' Dental explorers, also known as sickle probes, are tools found in the dental arsenal that are frequently utilised. The explorer is designed with a sharp tip at the end to improve tactile perception. In the past, it was usual for dentists to use the explorer to probe teeth for the presence of ...
A coordinate-measuring machine (CMM) is a device that measures the geometry of physical objects by sensing discrete points on the surface of the object with a probe. Various types of probes are used in CMMs, the most common being mechanical and laser sensors, though optical and white light sensors do exist.
