EL-550 Ozone Water Sensor: Compact UV Absorption Monitor

Ozone Water Sensors

The EL-550 is a compact ozone water sensor combining detection and processing in a single all-in-one housing. Using UV absorption technology, it measures dissolved ozone from 0-50 mg/L (default) with ranges up to 150 mg/L available. This cost-effective monitor features analog outputs (0-1V, 0-10V, or 4-20mA), digital display with rotary selection, and operates from 5-40°C water temperature. Ideal for industrial water treatment, research laboratories, and aquaculture applications requiring reliable ozone monitoring.

Key features

  • All-in-one housing: Detection and processing units are combined, resulting in a compact and space-saving design.
  • Cost-effective: By limiting functions to the essentials, both initial and operational costs are reduced.
  • Clear display options: Display of ozone concentration, sensor light intensity, and span value via a rotary switch facilitates monitoring and maintenance.


Measuring ranges

In units mg/L with a continuous measuring ineterval

  • 0-10.00
  • 0-20.0
  • 0-30.0
  • 0-40.0
  • 0-50.0 (acniti default)
  • 0-60.0
  • 0-100

Sampling method

Water pressure intake or suction by sampling pump is not included in the sensor. Order a sampling pump separetely here

Display function

Available (selection among ozone concentration, light intensity of the sensor or span by a rotary switch) When measuning ozone concentration, minimum figure of the indicator is as follows.

  • in case of 10 mg/L => 0.01 mg/L
  • in case of 20 - 60 mg/L => 0.1mg/L (acniti default)
  • in case of 100-150 mg/L => 1 mg/L

Analogue output

  • Voltage output 0-1V or 0-10 V DC
  • Current output 4-20mA DC (insulated)
