AquaChlor™ - Chlorine Sample Chamber
The AquaChlor
TM
sample chamber compensates for minor changes in sample pressure and flow. A flow
regulator is recommended to adjust the inlet flow to approximately 250 ml/min (see installation instructions
on pages 15 and 16). The chlorine sensor is inserted into the top of the flow chamber, into the port on the
left-hand side of the chamber. For applications that require pH measurement, the pH sensor is inserted into
the top of the flow chamber, into the port on the right hand side of the chamber.
The free chlorine sensor and optional pH sensor are connected to an AV38 local display. The AV38
calculates the concentration of free chlorine components. If an AV38 is not desired, the pH and chlorine
DataStick systems can be connected directly to a digital network without the AV38 display and the
compensation algorithm can be supplied and operated by a computer or PLC.
