Technology has become a part of our lives such a way that today it is completely impossible to imagine a life without technology. The developments in the field of science and technology has recently penetrated our lives so well that at times all of us not even aware of a mere fact that strategies and ways of technology and science are indispensable for our existence. In the present wake of such hardcore dependence on science, its tools, principles and practices etc, it is hard to believe that we must have a tool such as pH meter. Even if you might have never heard of it before, you should conscious it governs various locations our lives and irrespective of from which field you hail from, your life will be easier and much better if you would use a pH meter. The main significance of pH meter is to measure the extent of acidity or alkaline connected with a given liquid substance. Building sector of a digital pH meter is done in such a way that an unique glass rod or a probe is connected while digital meter and it assists in telling whether a substance is acidic or alkaline and that too, till what extent. Given below is the type of industries which would find the pH meter very resourceful and pragmatic. The industries are: Scientific testing and labs etc. Spas and Pools Ecological testing Agricultural industry Boilers and cooling towers Wine producing plants and coffee applications For water testing and water treatments The present-day digital pH meters a great expanded and broad tool. Often, not a perfect manufacturing industries, but also researches need the use of pH meter for their various research purposes. Income field may vary as per the interest are with the researcher, but pH meter will be of use while researching various fields, such as biological, agricultural, chemical, environmental and a lot more. In fact, any type of manufacturing industry, pH meter does offer a significant role perform. A system's pH electrodes require periodic maintenance to scrub and calibrate them. The space of time between cleaning and calibration depends on process conditions and a person's accuracy and stability expectations. Overtime, electrical properties of the measuring and reference electrode change. Calibration in known-value pH solutions called buffers will correct for a multitude of these changes. Cleaning of the measuring sensor and reference junction will also help. However, just as batteries have a limited life, a pH electrode's lifetime is also finite. Even just in the 'friendliest' environments, pH electrodes need to be replaced eventually. Wiring requirements for pH electrodes very often will be much severe than thermocouple wiring, demanding very clean connections and short distances of wire (10 yards or less, despite gold-plated contacts and shielded cable) for accurate and reliable rating. As with thermocouples, however, drawbacks of electrode pH measurement are offset by the advantages: good accuracy and relative technical simplicity. The following conditions are hazardous to measurement (glass) electrodes: high temperatures, extreme pH levels (either acidic or alkaline), high ionic concentration as liquid, abrasion, hydrofluoric acid in the liquid (HF acid dissolves glass!), and any kind of fabric coating on their own surface from the glass.
