AutoClean Dissolved Oxygen monitor

Self cleaning for better control and reduced costs

ATI Model Q45D

The galvanic dissolved oxygen sensor uses a membrane to help process and analyse the concentration of oxygen, providing a reliable oxygen measurement.
The optional auto clean system provides effective removal of any build up of biological growth, keeping the dissolved oxygen system virtually maintenance free.

How it works:

The rugged 5 mil Teflon membrane resists mechanical abrasions and serves as a barrier to allow molecular oxygen to diffuse into the reaction cell where it is reduced. This reaction produces a small current which is proportional to oxygen concentration.

Features and Benefits:

  • The ATI auto-clean system uses high pressure air blasts to remove biological growth, contaminants, or other foulants from the sensor.
  • The automatic cleaning cycle frequency can be adjusted by the user, whether the cycle runs at every two hours or once a day.
  • The ATI based cartridge-based sensor allows for quick and easy maintenance (we have made our cartridge field-repairable)
