Q46H/79PR Total Chlorine Monitor

ATi’s Q46H/79PR Total Chlorine Monitor is a highly versatile on-line, continuous measuring system.

Continuous water quality monitoring of Total Chlorine

The Q46H/79PR Total Chlorine Monitor is a versatile, accurate, direct and reliable measuring system that does not require the addition of chemical reagents.

The basic sensing element used in the total chlorine monitor is a 3-electrode amperometric membrane sensor which measures chlorine directly. The chlorine measurement does not alter the sample or add any chemicals to the sample stream, so the water flow can return to the system if desired. In addition to total chlorine measurement, the Q46H/79PR is also available with an optional pH input which provides a two-parameter monitoring system.

Features & specifications

  • Membraned-covered amperometric sensor that measures total chlorine without the addition of pH buffer, iodide solution, or other reagents.
  • Optional pH Sensor
  • Programmable range options from 0.1 PPM to 200.0 PPM through 3 internal automatic ranges. User ranges of 2.000 PPM, 20.00 PPM, or 200.0 PPM.
  • AC or DC Power Options.
  • Analog Output Options.
  • PID Output.
  • Digital Communications. Available in either Profibus-DP or Modbus RTU.
  • Three 6 amp SPDT relays and two analog 4-20 mA outputs are standard. Software settings for relay control include setpoint, deadband, phase, delay, and fail safe. An optional 3-relay card, for 0-30 VDC signals, is available to bring the total to 6 relays.

Applications

The Q46H/79PR Total Chlorine Monitor is available for a wide range of applications including:

  • Potable water systems
  • Water reuse systems
  • Cooling towers
  • Aquariums
  • Wastewater treatment effluents.

Key benefits

  • Reagent free
  • Optional pH sensor
  • Large dynamic range
  • PID control
