1. Most water immersion probes working between – 10 ~ 55 ° C (14 ~ 131 ° f). If the temperature exceeds the limit, peeling will occur between components, resulting in permanent damage to the probe. Limit working temperature (customized) can reach -55 ~ 120 ° C (- 67 ~ 248 ° f).

2. Transducers should not be submerged for periods exceeding 8 hours. Allow 16 hours of dry time to ensure the life of the unit.

3. The focusing distance of the unfocused probe is about equal to its near-field length. Since the last maximum amplitude of the probe occurs at a distance equivalent to the near-field length, all probes cannot focus when it is greater than the near-field length.

4. At a given frequency and element size, the focal length of the probe is limited. The actual maximum amplitude of unfocused probe is about 0.6 times of the near-field length, and that of point focused probe is about 0.8 times of the near-field length, for line focused probe max amplitude may not correspond tothe nominal focusing. When the focus probe exceeds the above maximum but less than the near-field length, the increased sensitivity at the focus is not obvious.

5. For the problem of the long focus length transducer has a large offset in the center frequency near the focus point, please refer to the description on the probe test report.
