Manual TECHKON DENS

1.3 Design of DENS

DENS is a solidly designed measurement device which is very functional and easy to 
use. It is compact in size; the buttons can be reached with the index finger when the 
device is held. The display is clearly legible and a great advantage of DENS is, that it can 
be easily positioned on the measurement sample. 

The USB-connector is for battery charging. The mini-USB plug, which fits into the con-
nector at the side of the device, is part of the package.
