MINI STD/CTD model SD-204
                                  (Replaces earlier models SD-201, SD-202, and SD-203)

MINI STD/CTD with optional
sensor for dissolved oxygen
 
 

.

 A complete STD- system in a suitcase!


MINI STD/CTD model SD-204 is a compact, high performance and user friendly STD- instrument with numerous applications. The electronic design is based on sophisticated microprocessor technology. The  instrument body is made of molded polyurethane which makes the entire construction extremely rugged  and  field reliable. SD-204 is manufactured by SAIV in Bergen and distributed by Sensordata. 

After start command given by holding a magnet outside the instument   the standard MINI STD/CTD will basically measure,calculate, and record 

  • Conductivity 
  • Salinity
  • Temperature
  • Sound velocity
  • Depth 
Optional sensors which can be attached to model SD-204 are:
  • Dissolved oxygen 
  • Turbidity 
  • Fluorescense 
The instrument is normally used without cable. After being manually started by a magnet, it will measure and record the selected parameters at  a user selected repetition rate.
At any time after measurements are finished the recorded data may  be transferred to a PC for immediate processing by the special software MINISOFT 200.
MINI STD/CTD has become a widely used instrument  in research, education, underwater engineering and in offshore. 
Due to its ruggedness and reliability MINI STD has become a 
preferred instrument for measurement of temperature,salinity, density  and sound velocity profiles in offshore exploration work in the the North Sea and in the Barents sea.
Til now more than  280 units have been sold.
