The standard force measurement model uses a measurement force of 4mN during the measurement process. The low force model uses a measurement force of 0.75mN during the measurement process. 178-296 is the standard detector for low force models, using only a measurement force of 0.75mN. Optional Detector: In addition to the standard detector, it is also equipped with optional accessories for small holes, extremely small holes, tooth surfaces, and deep grooves for selection.
