TDS stands for Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS meter tells you your overall water purity level, which will be displayed on the screen in ppm (parts per million). The lower the TDS level, the purer the water, with 0 ppm being pure H2O.

The TDS meter is great for checking your tap water quality and knowing when to change a filter. The TDS meter is a great tool for drinking water, water filtration and purification, colloidal silver, hydroponics (test your nutrients), aquariums, RO/DI systems, pools and spas, commercial and industrial applications and more. The TDS meter is a rugged model that includes a protective carrying case. Pressing on the temperature button allows you to test the temperature of the water (allow 1-2 minutes for an accurate reading for the temperature compensation).

This is the world's most popular handheld TDS meter for both industry professionals and household use.

Features

  • Advanced CPU: Automatically calibrated temperature; 0 - 9990 ppm TDS tester measurement range with 1 ppm accuracy
  • Hold Button: Holds measurement value when meter is removed from water for convenient reading and recording
  • Temperature Button: Tests water in Celsius and Fahrenheit; 31 - 200 F degree range, 1 F degree accuracy
  • Auto-Off Function: Shuts off automatically after 10 minutes of inactivity to conserve battery life
  • Convenient: Comes with leather carrying case and clip, ideal for on-the-go requirements

TDS Meter Digital Water Tester - PPM Quality Testing Tool 3-in-1 (TDS, EC & Temp) High Accuracy Testers | Pocket Size Test Pen for Hydroponics, Ro System, Pools, Aquariums, Spa and Saltwater Tanks

 Ean: 5060514480076   |    PartNumber: 7Pros-TDS   |   Asin: B075TZZTXR

7Pros TDS meter is a small hand-held device used to indicate the Total Dissolved Solids in a solution, usually water. Since dissolved ionized solids such as salts and minerals increase the conductivity of a solution, a TDS meter measures the conductivity of the solution and estimates the TDS from that reading. The use of "TDS" (total dissolved solids) meters for analyzing the purity of fresh water has become widespread in recent years. Many aquarists use them to determine if tap water purification systems such as reverse osmosis (RO) or reverse osmosis/deionization (RO/DI) are working properly, or if deionizing resins need to be replaced.

Features: 4 Display modes: TDS - ppm & C EC - s/cm & C TDS - ppm & F EC - s/cm & F Auto shut off feature saves battery life Lock function facilitates easy reading and recording Measurement range: Conductivity: 0 - 9990 s/cm TDS: 0 - 5000 ppm (parts per million) Degrees Celsius: 0.1 - 80.0 C, Fahrenheit: 32.0 - 176.0 F Accuracy: 2% Portable, lightweight and includes carrying case (weight: 1.94oz, size: 6 x 1.2 x 0.55 inches).

Features

  • FACTORY CALIBRATED: the TDS meters are factory-calibrated at 342 ppm NaCl and designed to stay consistent
  • ACCURATE: TDS readings are adjusted with automatic temperature compensation, assuring users of consistent and accurate measurements of total dissolved solids
  • EASY TO USE: Get your testing results in seconds. Turn on, immerse the electrode in the testing liquid, press Hold button and read the numbers
  • HOLD AND AUTO-OFF FUNCTIONS: the tester has data-hold function, it locks your readings making it easy to record. The instrument will automatically shut down after 9 min of inactivity
  • WIDE USE: Ideal for all water quality testing, water purification applications, aquariums and saltwater tanks, wastewater regulation, aquaculture, hydroponics, laboratory and scientific testing, pools, ecology testing, colloidal silver, water treatment, etc.
