Lesson 4 – Parts of a Free Chlorine Measurement Signal (5:47)

Watch the video to learn the factors that impact a free chlorine measurement signal.

> pH: signal decreases as pH increases ⇒ Compensate for pH with Krypton Multi® system + Zirkon® pH sensor

> Analyte (free chlorine) concentration: Signal decreases as concentration decreases ⇒ Select proper measurement range (0 – 1000 ppb, 0 – 5 ppm, 0 – 10 ppm, or 0 – 20 ppm)

> Rate of flow: signal increases as flow rate increases ⇒ Argon StabiFlow® regulates incoming water flow to a consistent 8 gallons per hour across sensors

> Temperature: signal increases as temperature increases ⇒ Zirkon® FTG sensor automatically compensates for temperature changes

> Sensor cleanliness: signal decreases as sensor fouls ⇒ ASR® automatic sensor cleaning technology cleans sensor up to once per day, in addition to manual cleaning with a granular detergent as needed
