Multi-sensor capability
WARNING
The sensor ports must be kept free of obstruction. Blocked
sensor ports can lead to inaccurate and potentially dangerous
readings.
In diffusion mode, the atmosphere being measured reaches the sensors by diffusing through the vents at the bottom of the instrument. Normal air movements are enough to carry the sample to the sensors. The sensors react quickly to changes in the concentrations of the gases being measured.
Diffusion-style operation monitors only the atmosphere that immediately surrounds the detector.
The IQ Force can also be used to sample remote locations with the hand- aspirated sample-draw kit or with a motorized, continuous sample-draw pump (both available separately. During remote sampling, the gas sample is drawn into the sensor compartment through the probe assembly and a length of tubing. Remote sampling operations monitor only the atmosphere at the end of the sample-draw probe.
• Use of the hand-aspirated sample-draw kits is covered in Section Use of the motorized sample-draw pump is covered in Section A detailed description of the IQ Force probe assembly is given in Section 5.5
