**** CITREX H3 measures the gas temperature inside the measurement channel. While CITREX H3 is warm-
ing up, the temperature of the measurement channel, and hence also the temperature of the gas inside
the measurement channel, rises at the same time. The measurement channel volume is relatively small,
even for relatively high volumetric flows (e.g. PIF @ 60 L/min). If the temperature of the gas on entering
CITREX H3 is compared with gas temperature in the measurement channel, it becomes evident that the
temperature in the measurement channel is higher. Therefore the temperature of the gas entering the
CITREX H3 measurement channel should not be expected to equal the temperature displayed on the
screen because the temperature displayed is measured inside the CITREX H3 measurement channel.
