nnnn

testo 6721

nnnn

The testo 6721 is a budget dewpoint guard with

nnnn

switch contacts.

nnnn

Continuously monitoring a "simple" compressed air

nnnn

refrigeration dryer was often not economically viable

nnnn

in the past. This security gap is now closed with the

nnnn

testo 6721. Whether integrated into the refrigeration

nnnn

dryer or pneumatic machine, or retrofitted by the

nnnn

customer, the testo 6721 avoids damage caused by

nnnn

excessive humidity in compressed air.

nnnn

Areas of application:

nnnn

Since the testo 6721 has only aswitch output, it is

nnnn

primarily suited to monitoring limit values.

nnnn

measurement values cannot be output via an analog

nnnn

signal. The budget monitoring function is particularly

nnnn

suitable at machine level, in order to protect a

nnnn

system, e. g. compressed air refrigeration dryers,

nnnn

from humidity damage. This avoids costly repair

nnnn

work necessary by high humidity, leading to icing,

nnnn

corrosion, material adhesion, "water hammer"

nnnn

(mechanical damage due to accelerated water

nnnn

deposits), and much more.
