7 Manometer
The filtration pump continuously draws sample through the intake tube
(2) and pumps it into the overflow vessel (4) through the connection
tube (3). The flow rate can be set on the control panel (1). On the intake
side, a manometer (7) is installed for low pressure measurement.
For sample preparation, a sample filtration device (available as an
accessory) can be connected upstream.
Climate kit
(instrument option “O“)
The climate kit includes an electrical circulating air heating, two housing
ventilators and three temperature regulators. The temperature regula-
tors switch on the heating or ventilators if the temperature is less than
+15 °C or more than 40 °C. Thus the analyzer with the door closed is
suitable for all-season operation in the open. The climate kit is automat-
ically active when the switch on the power supply box is in the ON posi-
tion.
