Necessary Weight against density: Solid Samples only 
The machine calculates the density by Archimedes’ Principle, hence the machine cannot get the accurate 
result if the samples are under weight, the below table helps to prepare the samples. 

 
 

 

 
 

2. Liquid Mode Measurement:  

The Dak Densimeter also has the provision for Liquid density measurement. To measure the liquid density, an 
optional Liquid Density Kit would be required. This machine calculates density of a liquid sample by comparing the 
weight of a Standard Glass Sample in water with its weight in liquid test sample. Measurable liquid densities are: 

1) Room temperature liquid density 
2) Assumptive liquid density by setting the compensated liquid temperature  

   

                                     

                   

  

 

           Hanger                            Hook                            Beaker Stage                         50cc Beaker                 Standard Glass Sample   

Liquid Measurement is divides into 2 parts: 

 

1.

 

Memorizing of the reference glass weight, 

2.

 

Measuring density of the liquid. If the user is sure that reference is already memorized, part 1 may be 

skipped. 

 

PREPARATION 1 - Memorize the aerial gravity and the density of Standard Glass Sample at the Liquid 
Density Mode. Select Standard Measurement Mode for this measurement (see page 20 above).  

Part I: 
Memorizing of the reference weight & the density. 
Select REF. MEM. MODE. By pressing Key A and Clicking B till you reach the “REF. MEM. MODE” 
Follow the solid measurement procedure now 

1.

 

Place the glass reference in the air & press OK and wait till reading is taken. 

2.

 

Press B key when prompted (“NEXT=ENT / MEM=B”). This memorizes the aerial weight. Press Enter to 
proceed. 

3.

 

Place the GLASS REFERENCE in reference liquid & press OK and wait till reading is complete. 

4.

 

Press B key when prompted (“NEXT=ENT / MEM=B”). This memorizes the density of the Glass reference. 
Press Enter to proceed. 

The mass, volume & density shall be sent to the printer & PC 
Measure and memorize the aerial gravity and the density of Standard Glass Sample. 
Step of measurement at this Mode is entirely the same at the Standard Measurement Mode (see page 20 above).
