The OdaLog has been specifically designed for
the Wastewater Industry, primarily for locating at or close
to the source of Hydrogen Sulphide emissions such as within
sewerage pumping stations and receiving manholes.
Its purpose is to log levels of H2S in the
range 0-200 ppm for later downloading of data in tabular
or graphical form to highlight significant variations in
H2S levels over time.
Due to the nature of the environment in which
the instrument has to operate, it has been designed to be
splash resistant, robust, small, and able to log data for
extended periods of time.
The following is detailed information on this
globally recognised product.
Ability to customise graphical scale and
mark time intervals on X-axis
Records OdaLog L2 serial number on printout
and allows graphs to be labelled
Uses Infra Red Communication for downloading
and configuring

We recommend that the OdaLog is returned to an authorised
App-Tek service centre at least once every six months for a full inspection,
software upgrade as developed, calibration, test for linearity and
to have new batteries fitted.
12 month warranty when used in accordance with the operator's
manual (excluding calibration costs).
In the interest of continued improvement, we reserve
the right to change design features without prior notice.
