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.

TDS Meter Inline Tester- Dual Mode Reading - Easily Installs Inline - Very Simple To Use

TDS Meter - Dual Mode - Installs Inline - Check the TDS level with the push of a button. Now you can easily check to make sure the water from your reverse osmosis system is top quality. Measure the tap water coming in vs. the purified water going out of your system at any time. Very easy installation. Simply cut the line out from the RO membrane housing and install the inline probe between the membrane housing and the shutoff valve, when possible. The closer to the membrane housing the better. Insert the ends of the tube into the John Guest quick connectors on the TDS meter probe. Then cut the inlet feed water line to the system and install the other T/probe. FEATURES Displays TDS levels of the feed water and product water with in & out electrode probes. Highly efficient and accurate due to its advanced microprocessor technology. Auto-Off function conserves battery power. The unit shuts off automatically after 10 minutes of non-use. Dual Range 0-9990 ppm (From 0 - 999 ppm the resolution is 1 ppm. From 1000 to 9990 ppm, the resolution is 10 ppm, indicated by a blinking 'x10' image.) Factory Calibrated: our meters are calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver. Comes equipped with John Guest Quick-Connect T-fittings as shown. Installs quickly and easily. SPECIFICATIONS Range: 0-9990 ppm Accuracy: ±2% Cable Length: 24.5" (including sensor) Power source: 2 x 1.5V button cell batteries (included) Battery life: over 1000 hours of continuous use Size: 7.6 x 2 x 4.7 cm (3 x .8 x 1.9 in.) Weight: 79.4 g (2.8 oz.) Always know if your RO membrane is performing correctly!
