    In this video, I test out a new water testing gadget I recently picked up off Amazon. The HM Digital Com-80S Hydrometer can quickly test water for both Electrical Conductivity (EC) and Total Dissolved Solids (TDS).



    First, I test the TDS found in our current RV Park water supply, and then I check the water found in the nearby tidal estuary. The salty estuary water was, of course, extremely high in total dissolved solids versus the tap water over 6000 ppm compared to 38 ppm.

    Then, for fun, I try out my new Clearsource Ultra 3 stage water filter system to see if it would have any effect on the TDS reading. As expected, it hardly changed. Being that the solids are dissolved, they passed right through the filters, even the .2 micron one. To remove dissolved solids, one needs to use reverse osmosis, often referred to as RO, or something called a deionizing filter. Clearsource does sell a deionizing kit, and I plan to buy one and give it a try in the future.

    Overall I'm happy with the little TDS water testing gadget. I think it will come in handy as a for testing a questionable water source for dissolved solids.

    I would check the meter with your water supply before the filters. If your coming from a city water supply . The amount of dissolved solid is very very low or none existent. Most city system remove the dissolved material before it enters the system.

    Yeah, I did the city water before test 39 PPM. After the filter it actually rose to 60 then after running a bit it dropped to 41. Likely because the filters are very new, so figure the carbon one was still releasing a lot.
