Frequently asked questions
Answers to most common questions.
Check whether Bluetooth is switched on on the PoolLab® 2.0.
The Bluetooth symbol in the top bar on the PoolLab® 2.0 display must light up green.
Bluetooth is activated or deactivated on the PoolLab® 2.0 by pressing the Bluetooth/WiFi button twice. Make sure that the Bluetooth symbol on the PoolLab® 2.0 is green, then start the LabCOM app again and connect to the PoolLab® 2.0.
For Android users: Please make sure that the LabCOM app has been granted the 'Location detection' permission.
This is required by Android to establish Bluetooth connections.
The measuring sources must be actively selected and transferred.
To do this, tap the Bluetooth button on the PoolLab® 2.0 twice to switch on Bluetooth (symbol in the status bar lights up green), start the LabCOM app and connect the app to the PoolLab® 2.0 via the Connect button.
In the menu that then appears in the app, tap on the wrench next to the measurement sources and place a check mark next to the measurement sources (maximum 20) that are to be transferred to the PoolLab® 2.0. Please take a look on tutorial video.
• Double tap the Bluetooth button on your PoolLab 2.0.
• Ensure the Bluetooth icon at the top right is green.
• Open the LabCom app.
• Navigate to the Bluetooth tab in the app's lower navigation bar.
• Patiently wait for your device to appear.
• Once it does, select your device.
• This might happen if an update is interrupted, such as through power loss or disconnection from WiFi.
• Keep the device turned on for approximately 2 to 2.5 minutes to allow it to restore itself.
• Following this duration, the device should restart normally.
• The WiFi process is divided into various stages:
1. An orange blinking WiFi icon signifies that the device is attempting to connect to WiFi.
2. A blue blinking WiFi icon indicates successful WiFi connection and the device carrying out its online routine:
a. Uploading measurements (provided you've set up a cloud account and sampling point(s) on the device)
b. Downloading linked sampling points (provided you've set up a cloud account and sampling point(s) on the device)
c. Checking for updates
-> If updates are available, an update dialogue will be displayed
d. On completion of all tasks, a "check icon" will blink.
• Log into your cloud account in the LabCom app.
• Connect PoolLab 2.0 to the app using Bluetooth.
• Tap the wrench symbol in the "connected cloud account" field.
• Finally, tap the "send to PoolLab" button.
• Connect PoolLab 2.0 to the app via Bluetooth.
• Tap the wrench icon within the "sampling points" field.
• Choose your desired sampling points.
• Tap the "send to PoolLab" button.
Note: Remember to repeat these steps if you're not logged into your cloud account in the app, as this will need to be done before you can utilize the WiFi cloud feature on your PoolLab 2.0.
In LabCOM's app/software/web application, the active chlorine calculator is based on J. O'Brien's work, which also is used by the US Environmental Protection Agency (USEPA). Detailed information about this calculation methodology can be found in the USEPA calculator documentation at:
The listed formulas in the documentation are all derived from O'Brien's work and have been extensively reprocessed.
This system provides an almost identical concentration of HOCl as the LabCOM active chlorine calculator, but the cyanuric acid (CYA) setting of the USEPA calculator is limited to a maximum of 10mg/l.
To better understand the subject of cyanuric acid setting it is recommended to read the following article which covers the subject in a well understandable manner:
CYA is only available in the middle measurement chamber, therefore it can’t be selected in the left and right chambers.
Certain parameters are only measurable within the middle chamber, and thus, can only be selected from the T2 list.
The parameters restricted to the middle chamber include:
• 6–CH Calcium Hardness
• 12–CYA Cyanuric Acid
• 22–PPHR Phosphate HR
• 23–POT Potassium
• 24–SULF Sulfate
The pH liquid method doesn't necessitate a countdown because it operates without any suspended particles in the water. Therefore, once you have adequately stirred the reagent, you can proceed directly to the measurement by pressing the 'Test' button. This action serves as your confirmation, and the method will measure without a countdown.
No, it isn't a requirement to measure three parameters at once. You have the flexibility to measure any combination of 1 to 3 parameters. However, bear in mind that some parameters can only be measured independently and others are exclusively measurable in the middle chamber. As such, not all combinations are feasible. This is outlined in more detail for each parameter in the User-Manual.
No, it isn't mandatory to use the WiFi feature of PoolLab 2.0. You also have the option to set sampling points and transfer measurement data via Bluetooth using the LabCom app. In addition, device updates can be performed through Bluetooth, although they may take slightly longer compared to updates performed via WiFi.
Due to the absence of suspended particles generated by liquid reagents that need to "settle" before measurement to prevent interference with the light beam, there is no need for a waiting period or countdown in these procedures. Once the TEST key is pressed, the measurement is promptly initiated, and the result is immediately displayed.
If you encounter an error after entering a 32-character WiFi password into the PoolLab 2.0, it cannot be resolved. Kindly contact Water-i.d. (email@example.com) to arrange for a replacement device. Before connecting the replacement device to a WiFi network, please ensure to update it via Bluetooth.
To prevent your PoolLab 2.0 from automatically shutting down during the necessary waiting period, we recommend connecting your PoolLab 2.0 to the LabCOM app and adjusting the auto-off time to a minimum of 800 seconds (The device is programmed to automatically shut down after a default duration of 5 minutes (300 seconds)).
• Quick Guide: Find detailed instructions on how to connect your PoolLab 2.0 with the LabCOM app in the quick guide.
• Manuals: Refer to specific pages (Calcium Hardness (6–CH): page 73, Nitrate (16–NTRA): page 127, Urea (26–UREA): page 177) in user manual for step-by-step instructions.
All the necessary instructions can be downloaded from this webpage (https://poollab.org/v2/en#download).
Note: Please note that the required waiting time for Calcium Hardness is 10 minutes, for Nitrate it is 10 minutes, and for Urea it is 5 minutes.
