Pahlén Autodos - measuring and control unit
Autodos is the easy way to manage water quality
Highly intelligent Autodos for commercial pools.
The optimum solution for the public swimming pool is to install a Pahlén Autodos in the
system. The water quality is continuously monitored, which makes it easier to maintain a
clear and clean water. Through the use of automatic dosing, the chemical consumption is
controlled and optimized, as a result of a more even flow of chemicals.
Additional control and disinfection are obtained with a Pahlén CO2 unit and UV light.
Autodos is a well known, reliable and tested technology in it´s third generation when it
comes to measuring and monitoring. Autodos is available in a variety of versions and can
monitor pH and chlorine in the form of redox, free chlorine and combined chlorine.
Autodos offers a wide range of adjustments to suit all pool types. Chlorine, pH, flow and
temperature readings are shown in clear and easy to read LED displays. Autodos is easy
to use and provides exact readings for accurate monitoring and disinfection of pool water.
Furthermore it is very easy for the operator to overwiew and control the water quality.
Pahlén’s in-house developed Autodos is available for all requirements, from the
Autodos M1 which is a single-channel instrument for monitoring of pH, redox, free chlorine
or total chlorine, to the most advanced Autodos M3 which is a three-channel instrument
for monitoring of pH, free chlorine and combined chlorine.
The Autodos has a new flow cell. This new flow cell in transparent PVC has a separate
module for each electrode. Each module can be connected in series depending on the
application and the number of electrodes used. The starting module contains prefilter,
flow meter, flow guard, temperature sensor and a visual indication of the flow
through the flow cell.
The flow cell is neatly concealed with a transparent cover, that is easy to open when needed
e.g. for calibration and taking samples.
Electronic digital control panel
- Easy access to all functions from the control panel
- Clear overview of free chlorine, combined chlorine and pH values
- Clear display of temperature (°C)
- Clear display of the flow (l/h)
- Clear indication when a too low or too high value
The new designed Autodos has a flow cell module that is tiltable forward. This makes the maintenance easier than ever.
The Autodos is also equipped with a transparent cover in front of the flow cell module that makes it
easy to see that there is a flow through the unit. The flow rate can also be read on the display panel.
