Introduction
A. Overview
Blue Connect continuously measures the key parameters of your swimming pool (temperature, pH,
ORP/Redox, conductivity). It also informs you of the external temperature and weather based on your
geolocation. The results of this analysis are then communicated to you via notications on the
“Blue Connect“ app (available on smartphone and tablet, compatible with Android™ and iOS). If the
device detects that one of the parameters is incorrect, an alert informs you of this status and provides
you with the instructions to follow to regulate and stabilize this parameter in order to maintain a
healthy and balanced water.
Blue Connect measures the following:
» Water temperature (°C, °F): An elevated temperature reduces the efficiency of disinfectant product
and promotes the development of microorganisms.
» pH (hydrogen potential): this value measures the acidic or basic character of a medium. pH
contributes to the effectiveness of the disinfectant.
» ORP/REDOX (measurement of active chlorine in mV): The ORP measure is reflected in milli-volts
(mV). The measurement taken by the ORP probe of your Blue is a voltage in milli-volts (mV), which
represents the more or less oxidizing nature of your pool’s water.
» Conductivity1 (μS): Measurement of the concentration of inorganic salts in the water by the ability
of the latter to conduct electricity.

B. Precautions for use
» Do not use Blue Connect for anything other than water analysis.
» Blue Connect is not a toy. Avoid shocks as they may damage it.
» Keep Blue Connect out of reach of children when handling it (e.g. calibration and standby) due to
the use of chemicals. Store calibration products out of reach of children.
» Do not open the top part of the device (except when replacing the battery). Follow carefully the
battery replacement instructions. Damage caused by liquids is not covered by the warranty.
» Do not open the bottom part of the device containing the probe (except when replacing the
probe). Follow carefully the probe replacement instructions. Damage caused by liquids is not
covered by the warranty.
» Make sure not to leave the probe out of the water without the storage cap filled with KCl (saturated
potassium chloride), pH4 or, as a last resort, running water with a good amount of cooking salt.
» Do not use demineralized water in the storage cap.

For salt pools, salinity (more precisely the total salt content) is measured on the conductivity basis. The salinity measured
by the Blue is expressed in grams per liter (g/L) of TDS (Total Dissolved Solids). This is an estimate of the total amount of
dissolved species in the pool, based on the assumption that the main species is sodium chloride (NaCl or cooking salt).
Sodium chloride increases the conductivity of your pool water depending on its concentration. An estimate of the sodium
chloride level based on the conductivity will deviate even more if other unknown salts are present in your pool. This deviation
can be checked using colorimetric detection strips specic for sodium chloride.

» Make sure the top part of the unit is out of the water to allow the communication system to work.
» Do not leave Blue Connect in water with a temperature below 5°C or above 50°C.
» Keep the Blue Connect serial number and key2.
» Store Blue Connect sheltered from frost.
Content of the box
Blue Connect analyser: Delivered secured on the storage cap to
protect the probe during transportation. The probe is immersed in KCI
(saturated potassium chloride), which assures its protection.
The storage cap: Used to transport the probe out of the water or to
keep the sensors immersed during an extended storage (in winter
for example).
The usage cap: Must always be mounted on the device before placing
it in water. It protects the sensors from any damage.
Cord: Allows to x the device to a point of attachment.
Quick start guide: Helps you with the device start-up.

code (key) and the three last digits of the serial number (SN), which can both be found on
the back of the start guide or on the storage cap of the device.
To start the device, you must activate it. The top of the device has a wave shape. Place the
trough of the wave towards yourself and shake it sharply. You will hear two beeps, meaning
that the initial activation was successful.

Sigfox® is a telecommunications network specialised in the Internet of Things. It is a cellular network that does not interfere
with domestic Wi-Fi. You can check if your swimming pool is covered by the Sigfox® network by visiting www.sigfox.com/
coverage. Blue Connect uses Sigfox® to transfer data to your smartphone.

If the nut is not secured with a screw, tighten it securely. Do not hesitate to use a cloth to
avoid hurting your hand.
If the nut is secured with a screw, proceed to the next step.
Rinse the probe in clear water and place the usage cap on the external part of the device to
protect the probes.

Place Blue Connect in the swimming pool:
» In the pool: Leave it floating in the pool. If needed, you can secure it by fixing it to a point
of attachment with the cord and the rubber ring.
» In the technical room with Blue Fit505 (Cfr p.17).

Blue Fit50 is a Blue Connect accessory. It is available in the Blue Connect Plus pack, or sold separately.
B. Notes
» Do not leave the sensor exposed to air.
» The Sigfox® network connects automatically and sends measurements at regular intervals.
» The sensor may take a few hours to stabilise its parameters after its first immersion in the swimming
pool.
» In case of non-existent Sigfox® coverage, there are two options:
» Blue Connect operates in Bluetooth®. In such case, you must take daily Bluetooth®
measurement(s) for the device to perform its analyser work.
» Blue Extender6 allows Blue Connect to connect to your Wi-Fi network. For further information,
visit our website or contact your reseller.
Feel free to watch our Blue Connect start-up video available on www.blueconnect.io (help).
