Good day! Do i need to calibrate all the parameters or only pH?
@GainExpress4 ай бұрын
Hi Mopar, if the item is brand new no need to calibrate, it has been pre-calibrated at the factory. for pH calibration, use the pH buffer solutions for tds/ec/salt calibrations, Just a single calibration solution will suffice to ensure your equipment is properly calibrated. Just calibrate the EC for a hassle-free calibration process.

How to calibration tds ?
@GainExpress6 ай бұрын
to Calibrate the TDS, Instead of PH solution, use conductivity buffer solution ( 1413uS, 12.88ms, or 111.8ms) ex. you have 1413uS buffer solution. 1. Change the mode into EC 2. Immerse the meter into the 1413uS buffer solution. 3. Long press MODE/CAL to enter the calibration mode. 4. Wait until 1413 flashes 3x, and that's it. the calibration is done. you may now clean the probe with distilled water and dry it.

Hi, This is how to calibrate but how to test the pool water and what should each ideal reading level should be, Also if we have to calibrate after each use or even 5 uses then going back to liquid testing kit is the go. Thanks
@GainExpress Жыл бұрын
Thank you for your interest in our product. You can take a sample of water from the pool to measure the PH/TDS/EC/Salinity/TEMP levels. However, it's important to note that each country has its own standard level of these parameters, so please check the standard in your country. Regarding calibration, we recommend calibrating the pH every 2-3 days if the product is used frequently. Normally, there is no need to calibrate TDS/EC/Salinity. However, if you find that the readings are not accurate, then calibration may be necessary.
