3 жыл бұрын

This 5-in-1 water quality tester is an ideal tool for many type of water analysis all in one handy instrument. It has the following parameters.
pH - measure the Acidity and Basicity of a solution.
EC - measure the Electrical Conductivity of water that is use to help indicate water purity.
TDS - indicate the Total Dissolved Solids in a solution that is also an aid in many water analysis procedure.
Salinity - measure of the concentration of dissolved salts in water.
Temperature - knowing the temperature in water is an essential key factor in water analysis. Temperature influences the rate of chemical and biological reactions.

Need operating instructions for a beginner, not calibration. First, HOW TO USE to conduct each test.

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 ?

@GainExpress 10 ай бұрын

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.

Why the pH value is buffering and dont become stable after rinsing it with distilled water? It is not showing accurate value. How can i solve this?

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

@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.

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.

@GainExpress Жыл 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.

@@GainExpress hello. I tried this. The meter shows about 1600 instead of 1413, so it is not correct calibrated. If I press cal, it blinks, but afterwards it's still in the same range. I had about 21°C. What's wrong?
