Inlet sample specifications
1
Honeywell Analytics recommends thick-wall tubing (1/8” ID) for best speed of response. Due to
its lower surface area, thick- wall tubing may require less conditioning than thin-wall tubing.
2
The flow rate is electronically maintained at approximately 600 cc/min and may vary within
acceptable tolerances.
Tubing lengths vary among gases. See the Gas Chart for recommended lengths.
NOTE
Honeywell Analytics recommends the use of Teflon FEP (Fluorinated Ethylene Polymer)
tubing to assure proper sample transport. The properties of Teflon FEP make it the best
choice for transporting sample toxic gases to instruments when compared with the
properties of other similar tubing materials.
