ZERO FREE CHLORINE – Pi HaloSense (Zero)

Pi HaloSense Zero Free Chlorine Analyser is designed for water sample without chlorine.

The application include monitoring of drinking water for low range free chlorine, post carbon filter or post chlorine removal water.

Pi HaloSense Zero Free Chlorine Analyzer utilizes the principle of membrane covered potentiostatic Amperometric 3-electrode system. The third reference electrode eliminate zero drift and hence zero calibration is not required for this system.

Due to the unique design of chlorine sensor, Free chlorine measurement are largely pH independent which mean the measurement are bufferless and reagent free. pH compensation by pH sensor is not required too.


Pi Chlorine analyzer is designed to have low maintenance where the maintenance interval is only at 3 or even 6 months.

Features:

  • Pi CRONOS controller can support up to 2 Sensor Inputs
  • Pi CRIUS controller can support up to 4 Sensor Inputs
    and Remote Access Features via TCP/IP or GPRS (Require Activation Code)
  • Pi CRONOS and CRIUS Controller Support Modbus RS485 RTU/ASCII, TCP and ProfiBus Communication with Built In Timer, Logic and PID Control (Require Activation Code)
  • Reagent free system
