E2648-O3 Ozone Detector

Features

• Stable long-life electrochemical sensor

• Resolution 0,01 ppm O3
• Two SPST relays option
• 2 × 4-20 mA or 0-10 V, RS485

Description

Ozone detector-transmitter E2648-O3 is a member of new PluraSens® family of multifunctional measurement instruments.

Applications include swimming pools and spas, food factories, places where disinfection or bleaching is performed, and other areas, where potentially toxic concentration of ozone can accumulate. 

The instrument utilises a fully calibrated and temperature compensated electrochemical gas sensor with excellent repeatability, stability and long lifetime.

Two relays with closing contact (optional) may be used for remote signalling or concentration control. Two alarm set-points are user settable.

Two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol can be used to connect the detector to safety or building automation systems.
