PREPARATION…

Note. 

For 1 metre and 2 metre

dip systems using mechanical or
ultrasonic cleaning, please refer
to separate specification sheet.

Note.

 

For ultrasonic and

mechanical cleaning in Dip
systems, refer to the appropriate
manual for electrode details.

Note.

  For Intrinsically Safe

systems a maximum cable
length of 5 metres is permitted.

Note.

  For PVDF systems, only
