• A membrane-covered thermal conductivity (TC) sensor, either model 3127x for H2
measurement or model 31570 for N2 measurement.
• A flow chamber, either model 32013A with flow adjustment valve for N2 analyzers,
or model 32015 without flow adjustment valve for H2 analyzers.

Also included with your shipment are two C-type batteries, a recharge kit in a plastic case
containing materials to maintain your sensor and a model 32824A refilling hose to refill

Locate the instrument close to the sample being analyzed, and to the Personal Computer

right side of the instrument (see Fig 1-1 above).
Make sure you install a fully charged set of batteries, or connect the instrument to an
external power source (see “External Power Supply (optional)” on page11), before
switching the instrument on and exposing the sensor’s membrane to any liquid.
