HM Digital Dual Inline TDS Meter *DISCONTINUED*

Total Dissolved Solids (TDS) are the total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water, expressed in units of mg per unit volume of water (mg/L), also referred to as parts per million (ppm). TDS is directly related to the purity of water and the quality of water purification systems and affects everything that consumes, lives in, or uses water, whether organic or inorganic, whether for better or for worse. 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: HM Digital meters are calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver. Comes equipped with Mur-lok® Quick-Connect T-fittings. Installs quickly and easily. SPECIFICATIONS Size: 7.6 x 2 x 4.7 cm (3 x .8 x 1.9 in.) Range: 0-9990 ppm Accuracy: ±2% Conversion Factor: NaCl (avg. 0.5) Cable Length: 24.5 (including sensor) Fittings: 1/4 standard, also available with 3/8 or 1/2 Power source: 2 x 1.5V button cell batteries (LR44 or equivalent; included) Battery life: approx. 1000 hours of continuous use Weight: 79.4 g (2.8 oz.) UPC: 891144000052 Measure the tap water coming in vs. the purified water going out of your water filtration system at any time. Use the monitor to determine when the filters need to be changed.
