IEQ Chek Operation Manual
sensors at the tip of the temperature/RH probe, the relative humidity (RH) and
temperature levels are sampled to confirm the internal chamber readings. With the
optional IQ Chek™ software and datalogging kit, all instrument readings can be
stored for reference.

Fitting
The high humidity gas sample probe is approximately 3 feet in length and consists of
a rigid clear plastic tube, a combination of Nafion
between them. The Nafion tubing is used to prove more accurate readings by (a)
eliminating moisture from within the tube, and (b) equalizing the relative humidity
inside and outside of the tube.
The calibration/sample adapter is common to all pumped IEQ Chek™ versions. It
connects to the threaded brass fitting which is either located on the side of the
instrument (standard, single-probe versions) or on the back (dual-probe versions).
The temperature/RH probe is an electrical probe that has temperature and relative
humidity sensors on one end and a DIN-6 electrical connection on the other. This
probe connects to the mating DIN-6 connector located on the back of the dual-probe
IQ Chek™.
IMPORTANT:
otherwise the gas readings may be compromised.
