Review: Great product - Works great.
Review: Known brand, Very accurate, great in Aquarium related applications and to know your Tap water. - I purchased this to validate my custom built continuous exchange dripping water system for freshwater aquarium. I compared the readings with laboratory class instrument and the reading are very accurate per product specification. This product allows me not only validate the quality of water I use for my aquarium tanks, but also allowed me to realize how over chlorinated tap water is in my community , over 5ppm which is 25% above FDA recommended levels for US. I also can check and validate how household under the sink active carbon based water filter works and even whether bottled water is worth buying. This instruments reduced the risk of chlorine poisoning by making my family aware of what we drink. Highly recommended and easy to use.
