2. Install a length of tubing from the desired sample point to the sample port as shown below. Sample draw tub-
ing should be either teflon or stainless steel 1/4" OD. Sample flow rates are set between 500 and 1000 ml/m.
CAUTION:
When detecting for NH3, CL2, CLO2, or HCL care must be taken to use a minimum amount of stainless steel tub-
ing and connections because stainless steel readily absorbs these gasses and will cause significant error in the detection process.
Teflon tubing is recommended for these applications.
3. Install a length of tubing from the vent port and an area deemed safe for vent as shown below.
