4.8 Flow chamber installation
At the top of the TC sensor is a thermistor to measure the sample temperature. Do not bend or damage this
component.
The model 32013A or 32015 flow chamber allows the liquid or gaseous sample past the TC and
temperature sensors. The flow chamber attaches to the TC sensor with a threaded collar and is
sealed to the sensor with two O-rings (EPDM Ø20 × 2 mm and NBR Ø 4 × 1.5 mm).
The flow chamber's inlet and outlet use ¼-inch diameter transparent plastic tubing. Connect by
compression fittings to the sample source and to the drain, respectively.
You may also have received a model 32051 sample tube adapter to attach the flow chamber inlet
tubing to the sampling point.

4.9 Instrument location
Locate the instrument close to the sample being analyzed, and to the PC if one is being used. A
LEMO-6 connector for RS-232 serial output to a PC is on the right side of the instrument. Refer to
Figure 1
on page 8.
Make sure you install a fully charged set of batteries, or connect the instrument to an external power
source before switching the instrument on and exposing the sensor's membrane to any liquid. Refer
to
External power supply (optional)
