Paracetic Acid Sensor

Key features

  • No chemical reagents means lower cost of ownership
  • Stable and reliable
  • Suitable for all potable, process and salt waters
  • Up to 6 months between maintenance
  • Up to 15 years life

Description

ORAKEL peracetic acid sensors are membrane devices which use no reagents, are extremely stable and have reduced maintenance and reduced whole life costs.

How it works
The membrane amperometric paracetic acid sensor is a two electrode sensor which operates at an elevated applied potential, which eliminates zero drift. Its unique design means that no reagents or buffers are required at all and calibration is a simple point (no zero required) operation.

Applications

Anywhere you have a requirement to measure residual CHз,COзH is a suitable application for the ORAKEL paracetic acid sensor. It is particularly suited to working in sites where reliability and ease of use are most important. Conductivity acids can be tolerated but the water must not contain any tensides.

    • Paracetic acid dosing control
    • Rinsers
    • CIP plants
    • Bottle washers
    • Sea water
    • Drinking water

Autoclean
In applications such as pulp and paper food preparation and waste water, where there is likely to be a build up of solids in the sample, the ORAKEL paracetic acid sensor can be equipped to automatically clean itself at regular intervals with all the benefits of no operator intervention. See the Autoflush datasheet for details.

Cost of ownership
With its reduced maintenance, reduced calibration and reduced spares requirements, the ORAKEL paracetic acid sensors are arguably the most cost effective paracetic acid analysers available.

In most situations, the ORAKEL paracetic acid analyser is able to control the dosing of CHз,COзH by adjusting flow rates, pump rates, or valve positions automatically to maintain the paracetic acid setpoint. Automatic dosing can significantly reduce reagent costs, and increase the level of control.
