TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS-EZ can tell 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-EZ is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants.) The TDS-EZ is a great tool for drinking water, water filtration and purification, hydroponics (test your nutrients), aquariums, RO/DI systems, pools and spas, and more.PH penprovides more reliable accuracy and durability for testing the acidity or alkalinity of liquids. It is very easy to use - just immerse the electrode and the readings are automatically displayed. With a resolution of 0.01pH and a 0.05pH range of error, yo...

Automated instructions on the LCD screen aid in routine operation. The meter is splashproof, and the lamp and filter are protected from dust and dirt by a transparent cup, making it suitable for field applications. The device uses a positive-locking system to help ensure consistent positioning of the cuvette. Sulfate photometers measure the sulfate content in water samples, and are commonly used in the water quality and beverage production industries. Range is 0 to 150 mg/L. Accuracy is + or - 1 mg/L, + or - 5% of reading, with a resolution of 1 mg/L. Dimensions are...

The Nutradip Ph Meter Will Continuously Measure The Acidity Or Alkalinity Level Of Your Nutrient Solution, A Critical Factor In Successful Hydroponic Growing. The Maintenance Of Proper Ph Levels In Soilless Gardening Is Critical To Plant Health And Yield. An Imbalanced Ph Level In The Nutrient Solution Can &Quot;Lock Out&Quot; Nutrients And Cause Plant Deficiencies When The Ph Is Too Low (More Acidic). Alternately, Nutrient Will Become Trapped And Over-Fertilize The Plant(S) When The Alkalinity Is Too High.
