A trusted sensor for reliably measuring dissolved ozone

The Rosemount 499AOZ dissolved ozone sensor is an easy-to-use amperometric sensor with a rugged
construction. This sensor is ideal for measuring dissolved ozone concentrations in municipal water
filtration, bottling, and food processing plants.

Rosemount 499AOZ October 2019

Overview

Ease of maintenance

■

Extend sensor life with simple membrane and electrolyte
replacement; no special tools needed.

■

Automatic temperature correction with integral Pt-100
resistance temperature device (RTD).

■

Variopol (VP6) cable connector option eliminates cable
twisting and allows for quick sensor replacement.

High performance design

■

Measures dissolved ozone concentrations between 0 and 3
ppm.

■

Operates in process temperatures up to 122 °F (50 °C) and
process pressures up to 65 psig.

■

Polysulfone sensor body with forward and rear facing 1-in.
male national pipe thread (MNPT) process connections.

■

Internal flexible bladder allows automatic pressure
equalization for minimal influence from pressure changes
on sensor response.
