1.5 Vapor purge
The Turb 2000 series 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 Turb 2000 series 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 WTW or the local representative. Refer to section
9.2 R
EPLACING OR INSTALLING THE DESICCANT .
The desiccant can activate an alarm to notify the operator of a saturated desiccant. See section 6.15
D
ESICCANT ALARM.
