Dissolved Oxygen (Ppm And Ppb) And Ozone; Dissolved Oxygen / Ozone Interface Overview - Thermo Scientific Scientific AquaSensors DataStick User Manual

Note: Although toroidal conductivity cells are exceptionally robust, they can be damaged by physical
abuse, such as being struck against a hard surface.

Dissolved Oxygen (PPM and PPB) and Ozone

The Dissolved Oxygen and Ozone sensor heads have a number of physical features that should be noted. The connector is keyed.
The key provides protection for the pins during installation. To insure that pins remain free of moisture and dirt, a rubber boot is supplied
with replacement sensor heads and should be kept in place when the sensor is being transferred or placed in storage. In very humid or
dirty environments, we also recommend applying some electrical grease to the connector pins.
Keep the O-Ring and the shaft of the sensor free of dirt. Be sure the DataStick cavity is also free of dirt and moisture prior to insertion.

Dissolved Oxygen / Ozone Interface Overview

When an Dissolved Oxygen / Ozone sensor heads are installed in the DataStick, AquaComm™ will automatically display ppm,
temperature, sensor type and DataStick serial number. Pull-down menus will also automatically provide calibration, configuration
and diagnostic choices.
Factory default configurations for a dissolved oxygen or ozone sensor head are:
•
Units of measure: ppm ) (options include % and ppb)
•
Units for temperature: °C (options include °F)
•
Sensor Filter: 1 Second (options include 0 to 100 seconds in 1 second increments)
•
Temperature Filter: 1 Second (options include 0 to 100 seconds in 1 second increments)
•
Salinity: 0 mS/cm (options from 0 to 999.9 mS/cm)
•
Atmospheric Pressure: 760 mmHg (options from 539.2 to 792.4 mmHg)
