Colorimetry Turbidity Spectrophotometry Colorimeters and Turbidity meters both employ optical measurements. Optical measurements use light to quantify the amount of a colored or cloudy sample. Colorimeters are used to measure the concentration of a sample component. Turbidity meters can determine how cloudy the sample is and report a number value for the turbidity. Colorimetic measurements …

Dissolved Oxygen Probes Dissolved oxygen is often referred to as DO. It is a measure of the amount of oxygen in a solution. While some gases react chemically with water to form new compounds, gases like nitrogen and oxygen dissolve in water, without a chemical reaction and exist as microscopic bubbles between water molecules.  Air …

Conductivity Cells Electrical conductivity is an inherent property of most materials, and ranges from extremely conductive materials such as metals to non-conductive materials like plastic or glass. In between the two extremes are aqueous solutions, such as sea water and plating baths.  In metals, the electrical current is carried by electrons while in water it …

Ion Selective Electrodes Measurement by ISE can be performed in virtually every laboratory. ISEs measure ion concentrations in samples such as water, food, pharmaceuticals and biological samples. There have been many analytical methods that have been developed and published world-wide for the use of ISEs. The variety of methods available is the main advantage of …

pH electrodes The Thermo Scientific Orion electrode line offers a wide variety of quality pH electrodes to choose from. There are many different factors to consider when you selecting a pH electrode to ensure you select the electrode that will suit your needs. You will need to consider body materials, body styles, and sample requirements. …

Implementation of emission measurements Depending on the size and type of installation, you must demonstrate periodically that the installation meets the government imposed directives and decisions. Examples of these guidelines are: Calibration and annual control measurements automatic measurement systems (QAL2- and AST measurements according to EN 14181) Dutch Emission Guidelines (ner) Decision Combustion Emission Requirements …

ACP SR 25 Condensate Pump Peristaltic pump type ASR 25 / ACP 001    Application This pump is designed for continuous drain your condensate. This can be built into the bottom of a separator or gas cooler / container. The design is such that back flow is impossible in your cooler. The flow rate of 0.25 liters per …

AMP Membrane pumps Gas diaphragm pumps The basic design is simple and reliable. An elastic diaphragm is moved up and down by an engine cam. The entry and exit valves determine the flow. These pumps are completely oil-Fri  These pumps are available in different versions. We have one in sight of the most common.  AMP 416 (Ex) – Materials …

Calomat 6 Calomat 6, For continuous measurement of hydrogen and noble gases, the thermal conductivity of the sample gas mixture is measured and used to calculate the concentration. Only binary gas mixtures can be measured directly. If more than two components are present, the concentration of all other constituents must be measured separately using other …
