HF scientific AccUView UV %Transmission Monitor - Manual (Page 9)

1.4 Vapor Purge
The AccUView is equipped with a continuous vapor purge system. A replaceable
desiccant pouch in the lower portion of the instrument dries the air. System heat is used to
warm the air. A fan inside the instrument continuously circulates heated dry air around the
optical well and the flow through cuvette. This feature eliminates the need for a dry purge
line.
The AccUView monitors the replaceable desiccant pouch condition continuously. The
LCD display will show DESC on the lower line in the event that the desiccant pouch
needs replacement. Replacement desiccant pouches are available from HF scientific, or
the local representative (Part # 21555R). Refer to section 9.2 Replacing or Installing the
Desiccant Pouch
