Important Safety Note
The manufacturer states that the TKSA 71 must not be used where there is a risk of explosion. It is not presented as an ATEX- or IECEx-certified alignment instrument; hazardous-area suitability must therefore be confirmed separately before use aboard tankers, gas carriers or offshore installations.
