Monitor CTD+

Product Name:Monitor CTD+
Description:The MONITOR CTD+ utilises the same accurate, robust sensors and synchronised sampling techniques as the MIDAS range, but packaged as a smaller, lightweight unit to suit small boat or shallow water applications. The addition of a an extra sensor makes the MONITOR CTD+ a versatile and cost effective tool for gathering profiles of CTD and one other parameter of either Turbidity, Dissolved Oxygen or Chorophyll.
