Mercury in Water Test Strips <50, 50, 100, 200, 500, 1000 ppm Bottle of 50 Test Strips, Result in 3 Minutes Mercury Check for water quality testing is a quick and easy method to test for high levels of Mercury. How to use metals check test strip: The test procedure for this test is simple and quick. Just dip one test strip into a 200 mL (7 oz) or greater water sample. Move the strip in a back and forth motion for 60 seconds. Remove the strip from the water sample and shake once to remove the excess water. Wait 30 seconds and then match to the closest color. Sensitivity: <50, 50, 100, 200, 500, 1000 ppm (mg/L) Total test time: 3 minutes 50 tests per bottle US Patent No. 6541369

DM-1: In-Line Dual TDS Monitor Measure the tap water coming in vs. the purified water going out of your water filtration system at any time. 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: 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.

Drinking Water Test for Chlorine, Hardness and pH. Find out if your water has harmful levels of chlorine or hardness! This water test will let you test your water once for chlorine and once for hardness. Studies have found, that regularly drinking tap water with high levels of chlorine byproducts increases the risk of some forms of cancer. Water hardness can cause lime scale and higher detergent use. Calcium and magnesium, the chemicals that cause water hardness, are not easily detected, but may cause numerous negative effects. In fact, calcium and magnesium buildup may eventually damage plumbing and water heaters.
