Ph Meter

Ph meter is a specific type of voltameter with a very high impedance of input channels highly suitable for potenciometric ph measurements. Voltage produced by the ph electrode is proportional to logartithm of the h+ activity. Ph meter voltameter display is scaled in such a way that the displayed result of measurement is just the ph of the solution. Commercial ph electrodes used in ph meters consist of a h+ selective membrane, and internal and external reference electrodes, usually combined in one housing.

Ph can be measured using either ph indicators (like phenolophtaleine) - in form of solution or ph strips - or using potentiometric method. Strips are very useful when all you need is 0.5-1 ph unit accuracy. When you need higher precision, ph meter is the only way to go. In potentiometric methods you measure potential difference between known reference electrode and the measuring ph electrode. The latter depends on the activities of ions you want to measure. This dependence is described by nernst equation, thus once the potential has been measured you can calculate the activity.

Ph meters range from simple and inexpensive pen-like devices to complex and expensive laboratory instruments with computer interfaces and several inputs for indicator (ion-sensitive, redox), reference electrodes, and temperature sensors such as thermoresistors or thermocouples. Cheaper models sometimes require that temperature measurements be entered to adjust for the slight variation in ph caused by temperature. Specialty meters and probes are available for use in special applications, harsh environments, etc. Pocket ph meter are readily available today for a few tens of dollars that automatically compensate for temperature.

This ph test meter is very easy to use that is again fully accurate and come with affordable range. Different sizes of ph meter that fit in either hand with clear and accurate readings and digitally displaying system are available in the market. High level of resolution, wide mv range with power requirement makes this analytical instrument is suitable for different type of analytical applications.

This ph meter eliminates guesswork and allows instant ph readings at critical moments. Universally this scientific laboratory equipment is applied for the measuring the ph measurements of different samples. In cosmetic and in the industry of detergents suitable application this ph meter is done. For the sample tests in the food processing units, water plants and in the soil this ph meter that includes water ph meter, soil ph meter, ph conductivity meter and others are very effective.
