ORP-C Monitor

The ORP-C Monitor offers a high level of felxibility in controlling water treament applications. Our unique USB feature provides the ability to upgrade the software in the controller to the lates version.

Four Relay Outputs may be set to a Variety of Control Modes:

• On/Off set point control
• Time Proportional control
• Pulse Proportional (when purchased with Pulse solid state opto outputs)
• PID Control (when purchased with Pulse solid state opto outputs)
• Activate with a contact closure
• Timed activation triggered by aWater Contactor or Paddlewheel flow meter's accumulated total flow
• Activate with another output
• Activate as a percent another output's on-time
• Daily, Weekly, 2-week or 4-week timers with or without Biocide functions
• Intermittent sampling for boilers with proportional blowdown, controlling on a trapped sample
• Dual set point
• Always on unless interlocked
• Probe Wash timer
• Diagnostic Alarm triggered by:
  • High or Low sensor reading
  • No Flow
  • Relay output timeout
  • Sensor error

Measure Ozone in water with ORP Meters

How does an ORP Meter work?

ORP stands for oxidation-reduction potential. It is a measure of the ability of a solution to oxidize or reduce other substances.  ORP may also be referred to as redox Potential. 

ORP levels in water can be measured with an electronic  ORP meter.  ORP meters use electrodes in water that measure the voltage difference between the two electrodes.  Water with a higher potential to lose electrons (oxidize) will create a higher ORP reading, measured in Millivolts (mv).  Lower, (potentially negative) ORP values indicate the water is more reducing.

Using ORP to Measure Dissolved Ozone

ORP meters can indicate dissolved ozone levels in water. Ozone, being a strong oxidizer, increases water's ORP. However, other factors like pH, dissolved oxygen, and other substances can also affect ORP, meaning there's no direct correlation between ORP values and ozone levels.

For specific applications, ORP meters can be calibrated or correlated to known ozone levels, provided other water parameters remain stable. This makes ORP valuable for monitoring changes in dissolved ozone and general water quality.

These tools can be used to measure ozone in water for correlation purposes:
