SGM lab solution introduces its most demanded water testing instrument which is known as Dissolved Oxygen Meter. Dissolved Oxygen Meter is very useful instrument for determining factors in a swimming pool, spa and water from of other places too. In other words, dissolved oxygen analysis measures the amount of gaseous oxygen (O2) dissolved in an aqueous solution.
The most common application is to measure the exhaust gas concentration of oxygen for internal combustion engines in automobiles and other vehicles. Divers also use a similar device to measure the partial pressure of oxygen in their breathing gas.
Performance, exclusive features and value are the benefits of this complete line of dissolved oxygen meters.
The sensor does not actually measure oxygen concentration, but rather the difference between the amount of oxygen in the exhaust gas and the amount of oxygen in air. Rich mixture causes an oxygen demand. This demand causes a voltage to build up, due to transportation of oxygen ions through the sensor layer. Lean mixture causes low voltage, since there is an oxygen excess.
In soil respiration studies oxygen sensors can be used in conjunction with carbon dioxide sensors to help improve the characterization of soil respiration.
The Clark-type electrode is the most used oxygen sensor for measuring oxygen dissolved in a liquid. The basic principle is that there is a cathode and an anode submersed in an electrolyte. Oxygen enters the sensor through a permeable membrane by diffusion, and is reduced at the cathode, creating a measurable electrical current.

A multi-function compact chemical reactor designed for hydrocarbon steam reforming was evaluated. The reactor design is based on diffusion bonded laminate micro-channel heat exchanger technology. The reactor consists of a combustor layer, which is sandwiched between two steam reforming layers. Between the two function layers, a temperature monitor and control layer is placed, which is designed to locate the temperature sensors. The combustor layer has four individually controlled combustion zones each connected to a separate fuel supply. The reactor design offers the potential to accurately control the temperature distribution along the length of the reactor using closed loop temperature control. The experimental results show that the variance of temperature along the reactor is negligible. The conversion efficiency of the combustor layer is approximately 90%. The heat transfer efficiency from combustion layer to reforming layers is 65% to 85% at 873 K and 673 K, respectively. The heat transfer rate to the reforming layers is sufficient to support a steam reformation of propane at a rate of 0.7 dm3/min (STP) with a steam to carbon ratio of 2 at 873 K.
pH is a measure of how acidic the water is. The pH meter electrode is the part that actually senses the pH in the solution or in other way, one can define pH as an electronic instrument used for measuring the pH (acidity or alkalinity) of a liquid.
A pH meter is a precise voltmeter that measures the potential difference, in thousandths of a volt (mV), between the reference electrode and the measuring pH electrode. It's scaled in such a way that it displays not the measured potential, but converts it to a display of pH. A typical pH meter consists of a special measuring probe (a glass electrode) connected to an electronic meter that measures and displays the pH reading.
The SGM- PHS can series are very economical microprocessor based pH/mV meter, is ideal for routine use in schools, laboratories and production plants.

TOC analyzers are big on performance. Add the extra capabilities of an Autosampler to automate your analysis or add a stand-alone Solids TOC Analyzer to analyze solids, sludges, and slurries. With outstanding accuracy, easy use, and reliability, SGM Analytical TOC analyzers are the preferred choice for your TOC measurement needs.
Total organic carbon (TOC) is the amount of carbon bound in an organic compound and is often used as a non-specific indicator of water quality or cleanliness of pharmaceutical manufacturing equipment.
A typical analysis for TOC measures both the total carbon present and the so-called "inorganic carbon" (IC), the latter representing the content of dissolved carbon dioxide and carbonic acid salts. Subtracting the inorganic carbon from the total carbon yields TOC. Another common variant of TOC analysis involves removing the IC portion first and then measuring the leftover carbon. This method involves purging an acidified sample with carbon-free air or nitrogen prior to measurement, and so is more accurately called non-purgeable organic carbon (NPOC).
1. TOC is the first chemical analysis to be carried out on potential petroleum source rock in oil exploration. It is very important in detecting contaminants in drinking water, cooling water, water used in semiconductor manufacturing, and water for pharmaceutical use. Analysis may be made either as an online continuous measurement or a lab-based measurement.
2. TOC detection is an important measurement because of the effects it may have on the environment, human health, and manufacturing processes. TOC is a highly sensitive, non-specific measurement of all organics present in a sample. It, therefore, can be used to regulate the organic chemical discharge to the environment in a manufacturing plant. In addition, low TOC can confirm the absence of potentially harmful organic chemicals in water used to manufacture pharmaceutical products. TOC is also of interest in the field of potable water purification due to disinfection of by-products. Inorganic carbon poses little to no threat.

The hardness of water is due to the presence of magnesium and calcium. These make washing difficult, wastes soap, and creates unpleasant scum and scale deposits. With a zeolite system, the calcium and magnesium ions are substituted on a one-to-one basis with sodium ions from a conditioning resin. Once all the sodium ions are exhausted, the resin has to be regenerated.
Excessive hardness makes it difficult for soap to lather, leaves spots on dishware, reduces water flow and can cause pipe, valve and drain scaling
SGM Water hardness/ Water tests meter is an easy to use and inexpensive instrument for determining water hardness or softness.
You can measure the sodium content of feed and exit water in seconds. When the resin is exhausted of sodium, there will be no exchange and the meter will read the same value at the two ends. Only then should the resin be changed
High TDS may indicate hard water, which causes scale build-up in pipes and valves, inhibiting performance. Since TDS is related to water hardness, using a TDS meter can be your first step in determining the degree of hardness of the water. Generally, the higher the level of TDS (ppm), the higher the degree of hardness.
Water hardness is typically reported in grains per gallon, milligrams per liter (mg/l) or parts per million (ppm). One grain of hardness equals approximately 17.1 ppm (mg/L) in TDS.
