【Solar & Floating CL PH EC TDS ORP SALT TEMP Water Quality Tester 】Solar & WiFi Smart Remote Control Swimming Pool Residual Chlorine Tester, which is a multi-functional water quality tester, scan the QR code to download the free Android or IOS app (APP: YIERYI Smart) and install it. Add Solar & WiFi Residual Chlorine Tester and WiFi hub on APP, connect Solar & WiFi Residual Chlorine Tester to 2.4GHz WiFi, then you can monitor the changes of water quality anytime, anywhere, and you can know the P Residual Chlorine/PH/EC/TDS/ORP/SALT/TEMP of the swimming pool water in a more accurate, quicker, and more stable way.

【Expanding Residual Chlorine Water Quality Monitoring System】--You can customise the device name and even have multi-account management and multi-device management. Expandable to multiple Solar & WiFi Smart Remote Control Swimming Pool Residual Chlorine Tester, build a smart monitoring system for your pool or multiple pools to take over the pool monitoring tasks. In addition, the duct comes with an automatic temperature compensation function for better measurements, avoiding different temperatures affecting the measurement and ensuring accurate measurement data.


【Analyse Monitoring Data Anytime】--You can easily export the measurement data of Solar & WiFi Smart Remote Control Swimming Pool Residual Chlorine Meter, and view the historical data (monthly, weekly, daily) at any time, so that you can analyse the measurement data and save time. data, saving time and avoiding frequent recording and data loss.

【Scenario Setting / Alarm Mode for Exceeding Limit Values】--Solar & WiFi Smart Remote Control Swimming Pool Residual Chlorine Tester has an abnormal alarm mode, you can set the upper and lower limits of the measurement values (monthly, weekly, daily) at any time, so that you can analyse the measurement data and save time. You can set the upper and lower limits of the measurement values (only one value can be set at a time), when it reaches or falls below the set value, the remote monitor will send out an abnormal alarm in the APP to remind you to pay attention to the abnormal situation in time.

Frequently Asked Questions :

◆1.Why the residual chlorine value is 0 ?


The pool pH value should be within 6.5-8 and ORP value should be within 487-840, the residual chlorine value will be displayed normally.

If the ORP value is within 487-840, the residual chlorine value will be displayed normally, but if any one of these two values is out of the range, it will not be displayed normally.


◆2. Why can't I connect to WiFi?


Make sure the device and your mobile phone are in the same WiFi network environment, make sure WiFi - 2.4GHZ.


◆3. Dear, if you have any questions about the duct, please contact us, we have the video of removing the electrode cover before use, the video of instruction to connect the app, the calibration video of PH and ORP calibration (using calibration solution), even we have fessional technical engineers to answer your questions.
