Please check the values with a third device such as a photometer or other type of probe.
To compare measurements, they must be done in the same place.
Be aware that the probe may take a few hours to stabilize the parameters after it is first immersed in the pool.
- In the case of pH, a factory calibration has been carried out but it may be necessary to redo one. Place Blue in pH4 and let it act for several hours. Then, take a measurement using Bluetooth. If the pH value is more than 0.1, please follow the calibration procedure in the app in " Settings "> " My Blue Connect "> " Calibrate Blue Connect ".
- In the case of ORP, the values of an ORP probe in the technical room or in the pool may be different. The advice we give you is based on Blue's behavior in a pool. To find out if a calibration is necessary, place Blue in ORP 468. If the values are more than 20 mV away, contact us via the online support on our website www.blueconnect.io.
- In the case of salinity, note that the salt rate is estimated by our application on the basis of the conductivity. The calculation of this estimate may vary depending on the measuring device.
On the other hand, the test strips measure the NaCL while the Blue Connect measures the total amount of salts. The measures of Blue therefore contain the amount of sodium chloride but also other salts.
