A stainless steel casing has been selected to improve resistance to shocks, scratching, clamping, aggressive chemicals and pressure. The cable outlet design has also been improved to support the same constraint level.
The casing size has been minimized to the smallest possible dimensions necessary to hold the inner elements, such as electronics and acoustic absorber. Standard length is 40 mm, but a longer casing is possible upon request. Special casing diameter in imperial unit is also possible.
Lastly threading of the probe casing can be done on request.
