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.
