Household water is generally less than 500 ppm so the answer is no measurable part water can be measured here **Q: will this work to test salinity in salt pool ?** A: Hi, this model is mainly used for food. If you want to test salinity in a pool, you may consider the following model, which is mainly used for aquarium, swimming pool, pond for your reference as below. ASIN: B07FS6CZXN URL: https://www.amazon.com/dp/B07FS6CZXN?ref=myi_title_dp **Q: Can it test chlorides up to 100 thousand** A: Hi, do you mean can it test chloride up to 100,000 ppm? 100,000 ppm = 10%, the measuring range of this salinity refractometer is 0 - 28%, so it can test chloride up to 10%(100,000 ppm). **Q: Saltwater pool measurement?** A: Yes, this model can measure the salinity in the salt water pool. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice item *by J***P on 24 August 2023* Still good till now i used in my salt aquarium ### ⭐⭐⭐⭐⭐ Not the most expensive, but good *by S***E on 19 August 2020* Good value for money, more expensive named ones out there but this is just as good at a fraction of the cost.
