Get accurate readings and learn more about your water quality and hardness with the TDS3 Total Dissolved Solids Meter. The TDS3 measures water hardness in parts per million, ppm, by measuring electrical conductivity, ec, comes with a carrying case and displays total dissolved solids from 0-9999 and temperature from 0-99°C. Excellent for use with home aquariums, ponds, and hydroponics systems where TDS ranges need to be monitored and tuned. Make sure your water filter is working and get to understand the hardness of your tap water by using the TDS meter before water changes or water top offs. Too much dissolved solids in hard water can be detrimental to your equipment, livestock, or ecosystem balance. Typical water hardness readings: Distilled water – 0ppm RO DI water – 5-15ppm RO water – 15-20ppm City water – 50 – 500ppm Well water – 50 – 1000ppm Typical desired water hardness: Freshwater Aquarium – 75-180ppm Cichlid Aquarium – 100-200ppm Planted Aquarium – 50-125ppm Ponds – 50-250ppm Hydroponics – 600-800ppm Aquaponics – 150-350ppm Saltwater aquarium, for top off – 0-15ppm Meter specifications: TDS Range – 0-9999ppm Accuracy - +-/2% Temperature range – 0-99°C Size – 6” x 1.5” x 1.2” Package includes: - TDS and Temperature meter - Carrying case with clip - LR44 battery - Instructions

It works
About all I can say is that it works. Most other tds meters for sale on amazon are at least twice the price. It looks rather like the rest of them and is probably made in the same factory. I tested my tap water which i presumed was somewhat hard due to the presence of calcium and magnesium salts around the rim of pots and I tested some rainwater I had collected. The readings came out 172 ppm and 15ppm respectively which is about what I would expect.....especially the rainwater. So if you are a cheapskate like me give it a shot. You've only got 5 bucks to loose.
