How to use TECHKON DENS

1.1 Product description 

DENS  is  an  all-purpose,  modern  measurement  device  and  the  result  of  30  years  of 
experience we have as a long-established company in the development and manu-
facture of high-quality spectral measurement technology.

DENS was designed by applying our four powerful principles for perfect measurement 
devices:

  Easy and fast to use

  High measurement accuracy

  Solid and reliable

  Functional and attractive design

The new TECHKON DENS unifies three devices in one. It is a color reflection densi-
tometer for CMYK color prints, a film transmission densitometer and a high-precision 
illuminated magnifying glass for the visual control of printing results. 

This cost effective entry-level instrument allows everyone to perform a fundamental 
densitometric quality control on the basis of the reliable high accuracy well-known 
from all TECHKON instruments.

The DENS indicates densities, dot area and gray balance clearly legible on a large color 
display. Automatic color and gray balance detection speeds up the measuring. In ad-
dition the device is easily operated by only three buttons. The whole measurement is 
provided in a split of a second.

LED technology, durable and energy-saving, is used as light source. A multi-channel 
color sensor evaluates the measuring signal guaranteeing inter-instrument agreement 
with high-class spectrophotometers.

The integrated Li-Ion battery can be recharged very fast via the USB cable on any USB 
port and delivers energy for a few thousand measurements.

To meet the demands of a printing rooms harsh environment, the compact casing of 
the DENS is made of solid aluminum and is therefore very robust. Despite its solidity, 
the device weights only 330 g and due to its ergonomic and elegant design it is easy 
to handle.
