I take it from other ppl's questions in the comments and the response, that there are just 2 different calibrations needed for this device. 1. Calibrating the PH, like shown in this video and 2.) Calibrating the EC, which they say will also take care of " tds/ec/salt calibrations". This looked to be the answer about calibrating EC, but was response asked about TDS. I see it at Amazon saying for calibrating tds/ec/salt calibrations 5 in 1, $11.99 for 4 Bottles of 50mL. "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."
I see now from your profile that you might be in New Zealand, so idk about Amazon there, but the same seller has all three of these 1413uS, 12.88ms, or 111.8ms for the same price and all are for the same quantity of 4x 50ml bottles.
We kindly remind you to thoroughly clean the electrode before calibration. Additionally, it's essential to use fresh calibration solutions for accurate results. Should you require further information or assistance, please don't hesitate to reach out to us at info@gainexpress.com with your order ID. Thank you!
For tds/ec/salt do i have to calibrate it only with 1413 and 12.88 conductivity solution? Or do i have to calibrate seprately for ec, tds, salt respectively using other calibration solution ?
Hello! You'll be pleased to know that there's no need for separate 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.

Hello, you can calibrate it with any brand of standard solution. It's quite versatile in that regard, so feel free to use whichever brand you prefer for calibration.

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
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.
