Anchor to Specifications and Description


When working in the sciences or in a sanitation-based industry, it can be frustrating to use multiple readers when trying to measure pH, EC, TDS, and temperature, until now. Introducing the Combo pH/EC/TDS/C/PPM Tester & Temperature Monitor from Hanna Instruments. The waterproof design, simple operation, and replaceable electrode mean that you can rely on this meter for years. You can use this reader for any number of your pH needs, which are more common than you might think. This would be great in particular if you're working in the garden. If you own a pool or spa, farm fish, manufacture food, or work in the printing industry, you're going to need to understand the pH levels of your products. The included instructions should make it simple for you to properly test your subject, and the LCD display on the reader allows for easy identification of the pH and temperature levels of your water, soil, food, and more. And when you're done, this baby powers down automatically in case you forget. This reader is also top-of-the-line in terms of providing a clear and cheap gauge of soil acidity and basicity. pH, otherwise known as per-hydrogen, is measured on a scale of 0-14 with 7 being considered neutral. The 2 extremes of the scale are pure acidic or pure basic. Anything below 7 is considered acidic, and everything above is considered basic. In other words, your plants won't be able to absorb nutrients properly if the pH is off-balance, as most plants thrive in a slightly acidic to a neutral environment (between 5.5 and 7.0). For example, if the soil is too acidic, your plants may develop an iron deficiency and display yellowing on the leaves between their veins. If the soil is too basic, your plants won't be able to properly absorb nutrients like calcium, magnesium, and nitrogen, which are all paramount to plant life. If you're working in agriculture, food, printing, or simply own a pool, you're going to make sure your product stays balanced. Quickly, easily, and economically, you can gauge your pH, EC, TDS, and temperature levels with this reader from Hanna Instruments.
