TDS Meter - Test For Total Dissolved Solids In Water - Reverse Osmosis Membrane Tester - TDS Meter

TDS Meter - Tester. The Only Way To Know If Your Reverse Osmosis RO Membrane Is Performing Correctly - Tests for TDS - Total Dissolved Solids. A Must For All RO System Owners. Compare Incoming Feed Water To Treated Water - Replace Membrane If Less Than 80% of TDS Is Being Removed - Total dissolved solids (TDS) are the total weight of all solids (minerals, salts or metals) that are dissolved in a given volume of water expressed in milligrams per liter (mg/L), or in parts per million (PPM). The lower the TDS level in the water, the more efficiently your body's cells actually get hydrated by the water that you drink. The higher the TDS levels in the water, the greater the probability of harmful contaminants that can pose health risks or hinder the absorption of water molecules on the cellular level. 17 PPM of TDS = 1 grain of hardness. Highly efficient and accurate due to its advanced microprocessor technology. Hold Function: saves measurements for convenient reading and recording. Auto-off function: the meter shuts off automatically after 10 minutes of non-use to conserve batteries. Measurement Range: 0-9990ppm. From 0-999ppm, the resolution is in increments of 1ppm. From 1,000 to 9,990ppm, the resolution is in increments of 10ppm, indicated by a blinking 'x10' image. Display: large and easy-to-read LCD screen. Factory Calibrated: recalibration is not necessary, but can be done easily with a watch screwdriver. There's no need for messy solutions to initially calibrate the meter. Range: 0 - 9990ppm (mg/L) Accuracy: +/- 2% ATC: Built-in sensor for Automatic Temperature Compensation of 1 to 50 degrees Celsius (33 to 122 degrees Fahrenheit) Power source: 2 x 1.5V button cell batteries (included) Battery life: over 1,000 hours of continuous use Dimensions: 14 x 2.3 x 1.5cm (5.5 x .9 x .55 inches) Weight: 32g (1.13 oz) Simple to use for Reverse Osmosis membrane monitoring. Measure the incoming water and the RO water. Divide the larger number into the smaller number and subtract that decimal from 1. The resulting decimal is the percent of TDS that the membrane is removing. We really like this tester and think that anyone who wants to know about the quality of their water should have one of these TDS Meter Testers.

"Goes Green" Shower Soft Water Filter

Goes Green Shower Soft Water Filter - Top Of The Line Shower Filter. Uses 300 grams of pure KDF. Easy to install. Superior performance over carbon for chlorine removal in showers. Prevents bacterial growth. Good for one year or 30,000 gallons, which ever comes first. Help's enhance hair's pH balance, softens hair and skin. Helps preserve hair color. CHLORINE is an inorganic substance that chemically bonds to the protein in your hair and skin, destroying its natural ecological balance. Chlorine can leave your hair dry and brittle and make your skin flaky and itchy. As much as 50% of the chlorine taken into the body comes from skin absorption and inhalation. The other 50% is drinking water. KDF is far superior at removing chlorine than carbon in the shower. While carbon is great for drinking water filters, it is not great with hot water such as a shower. In hot water carbon can slough off some of the chemicals that it may have absorbed. That is why the package on the faucet & pitcher drinking water filters tell you to not use hot water in them. For hot water in the shower, KDF is "hands down" the best filtration media available. Installs easily between existing shower head and pipe. Shower head not included. Standard 1/2" NPT pipe thread size. Only 4 1/2" long by 2 1/2" diameter. With Convenient Replacable Cartridge. Order 2 or more and save even more!

Aquatec Permeate Pump ERP-1000

Aquatec Permeate Pump - The Aquatec ERP-1000 permeate pump is a turbine pump that uses the pressure of the waste water to pump the product drinking water into the storage tank. This protects the membrane from the back flow pressure of the tank, maintaining maximum osmotic pressure at all times. Great for low pressure applications. Increases product water purity Increases pressure and flow to the faucet Saves up to 3/4 of inlet water Up to 30% more tank pressure Faster tank refill recovery Increases filter and membrane life Requires no electricity Mounting Clip Supplied. Order the optional auto shut off valve that triggers at 90 percent rather than the standard 66 percent of tank pressure versus incoming line pressure. While the permeate pump works fine with a standard 66 percent auto shut off valve, the 90 percent valve increases storage capacity of the tank and increases initial pressure from the faucet. Will not install on most manifold systems such as Hydtrotech and Water Factory.
