Chi tiết sản phẩm

 Design and Function 

The instrument consists of a metal body with a cover plate. This plate serves as a platform for holding 6 glass strips measuring 300 x 25 mm 
onto which the coatings are applied. The six testing needles are fixed in a carrier device made of steel. 
The on/off switch and the control button for adjusting the running time (6, 12 or 24 hours) are located on one side. The instrument features 
three time scales which correspond to the respective speeds. 
The following track definitions conform to the degree of dryness of the coating: 
♦  No track                        Coating material runs together behind the needle 
♦  Continuous track        No flow of coating material 
♦  Rhombic track             Incipient surface dryness 
♦  Continuous track        On the surface Incipient through-dryness 
♦  Interrupted track          Incipient non-stickiness 
♦  No track                        Incipient handling fastness 
 
To determine the time of each transitional point the carrier device with the test needles is moved back by hand and the needles placed on the 
appropriate point. The relevant time can then be read off on the time scale.
