1 WATER PROBE SETUP

1.1 Connections

1.1.1 Air Loop

Two pieces of tubing connect the RAD7 and drying

unit to the Water Probe air/water exchanger, as

shown in Fig. 2. These two pieces of tubing can be

several tens of meters long. The standard tubing

supplied with the RAD7/Water Probe is suﬃcient for

a connection up to ten feet between the exchanger

and the RAD7.

Connect the OUTLET of the RAD7 to either of the

Water Probe air ports. For this, the 5ft long, 3/16" ID

1.1.2 DRYSTIK

Please note that the above instructions are for use of

the Water Probe without a DRYSTIK humidity

exchanger. A DRYSTIK, if available, should be placed

between the exchanger and the drying unit, and the

outer sheath should be purged with dry air from the

RAD7 outlet. See Fig. 3 in Section 3. More details are

provided in the DRYSTIK user's manual.

Introduction

tubing, with a 1/8" ID section at one end, may be

used. The 1/8" end ﬁts on the RAD7 outlet, and the

3/16" end ﬁts the Water Probe. Connect the other

3/16" hose connector between the other Water Probe

air port and the Laboratory Drying Unit.

Connect the other end of the Laboratory Drying Unit

(there should be at least one inch of blue desiccant

left at this end) to the air inlet ﬁlter (with 1/8" ID

tubing at the ﬁlter end), which is then placed on the

RAD7 INLET. The Luer taper ensures an airtight

connection.

1.1.3 RAD7 and Exchanger Location

Place the RAD7 on a clean, dry surface. If it has to be

located in a harsh environment, then it should be

protected from the elements (especially water). A

simple way to do this is to place the RAD7 inside a

large transparent plastic bag, such as the one in which

it was originally shipped. The bag opening should be

gathered around the inlet and outlet tubes, so that the

instrument is inside a closed space, completely
