This auto clean and sampling unit automates a series of events including sampling and cleaning the measuring cell or drying the system lines when connected to a general-purpose concentration meter, Density/specific gravity meter or Refractometer
[Features] 1) This unit is equipped with self-diagnostic function by checking keypad function and display screen. 2) The cleaning efficiency is increased by blending air into rinse solvent. By this way, the total amount of rinse solvent is decreased and saved. In addition, not only inside but outside of the nozzle can be cleaned very well since the rinse solution is fed from the outside of the nozzle unit. 3) Expensive sample materials like perfume or fragrance can be returned back to sample vials after measurements are over. 4) The DCU-551 series provides a variety of models with different specifications depending on what type of sample material is going to be measured; N type as standard model, SS type for small size sampling, H or HC type for high temperature or C type for low temperature measurement.
Standard model (N type) Small size sampling model (SS type) High temperature model (H type) : 20mL vials for use at ambient temperature. : 8mL vials for small size of liquid samples. Furthermore, the sensor, which inhibits over-sampling minimizes required amount of sample (approximate 5mL). : For those samples which are softened when heated, the sampling lines are heated up to 80degreeC.
