Acoustic Outputs on Activation
| Initial Operation | 106 N/m2 (1060 dyne/cm2) r.m.s. (during the pulse) pressure normalized to 1 metre range, that is, at a level of 160.5 dB vs 1 μPa at 1 metre |
| Immediately after 90 days continuous operation | 70 N/m2 (700 dyne/cm2) r.m.s. (during the pulse) pressure normalized at 1 metre range, that is, at a level of 157 dB vs 1 μPa at 1 metre |
Corrosion-resistance guaranteed
A newly formulated ceramic coating tops the already excellent corrosion protection. Hence the PT9 NINETY withstands the extreme environmental conditions at sea even longer. Approved in long term testing and guaranteed by us.
