Low-FLow FLow CeLL
Catalog No. 0044710
AppLiCAtion
Designed for use during low-flow sampling and well purging to route flow past the water
quality sensors of the Multi-Parameter TROLL 9500 or 9000. Seal between instrument
and flow cell prevents oxygenation of water prior to analysis. Clear material permits
visual inspection. Stabilizing ground stake (included) threads into base. 3-way intake
valve (included) may be used to divert flow for sample collection. Anti-siphon check
valve (included) prevents backflow at outlet. Stainless steel cuff fitting lessens reflection
during turbidity measurement. Accommodates
3
/8” and ½” tubing (tubing not included).
Optional base plate is available.

software volume calculations are correct.
2. Select the NPT/adapter fitting for the size hose to be used. Tape the NPT threads. Screw
into threaded holes in cylinder. Tighten by hand or with a wrench. Do not overtighten.
 It is not crucial to align the outlet directly over the inlet on the flow cell.

outflow as required.
TIP: The inlet and outlet
do not have to be exactly
aligned as shown here.
