FCL5500 Free Chlorine Controller / Transmitter

CLEAN >> Products > Transmitters > FCL5500 Free Chlorine Controller / Transmitter


		Revolutionary way to instantly get free chlorine value by using tri-electroded method measuring: faster and accurate, matching up to DPD results, without any reagent consuming.

●	Use Tri-electroded method to measure free chlorine faster and accurate, matching up to DPD results. Panel mounted type.
●	Measured value not affected by low temperature or turbidity.
●	NEMA4X, IP65 rated: waterproof, anti-gas. High protection against electromagnetic interference.
●	1 or 2 points calibration.
●	Two level password protection prevents unauthorized tampering with settings.
●	Large LCD, with high luminance LED orange backlight.
●	Two control modes: on/off limited control (LIT), proportion pulse length control (PLC).
●	Separately adjustable high and low set-point hysteresis (dead bands) prevent chattering of relays around the set points.
●	Washing/warning relays.
●	Scaleable isolated 0/4-20 mA outputs.
