*Explanation for Measurement methods
 
Immersion method: Uses capillarity by immersing a part of detector tube into the sample liquid.
Suction method: Suction of the sample liquid into the detector tube by attaching a rubber ball on one end of the tube.
Injection method: Injecting the sample liquid into the detector tube by a syringe.
