TDS-3 Digital Water Quality Tester

Product Instructions:Take off the pen case and turn ON the ON switch;Put the pen into the test solution, the height of the solution shall not exceed 2cm;Stir the pen in the solution. When the reading is stable (2-6 seconds), the TDS value will appear on the screen. Press HOLD to lock the value.After use, dry the water on the tip of the pen, clean it with pure water, and then cover it back.Precautions: Avoid soaking the TDS pen in water, avoiding direct sunlight, high temperature, and collision.Specification parameters:Lightweight and compact, weighing 28 grams, small and lightweight portable TDS instrument on the market today, 14.2 x 2.3 x 1.3 (CM) long and 2.3 x thick.Wide measuring range → able to measure 1-9999ppm.The application temperature is wide → working at 0-50 ° C, can be stored at -30 ° C.LIQUI D crystal display window → large screen liqui d crystal display waterproof design, easy to watch, durableLong battery life → 2 CR1620 3V batteries, can be used for more than 3 years, 10 minutes do not operate the automatic shutdown function, battery saving.Reasonable design → the electrode of the pen end can be directly inserted into the measured water solution for measurement, and the pen cover can also be used as the container of the tested water solution, which is very convenient.Measurement fast → due to the delicate naked sensing element, 5 seconds to complete a measurement.High accuracy →±1% error, high accuracy of titanium alloy probe, free from magnetic interference in water.Automatic temperature compensation → Automatically convert the indication value to the indication value at 25 degrees.
