Apparatus Used In Water Testing Labs

By Marissa Velazquez


Apparatus used to carry out water testing are specially designed to study industrial aqua and water used for factory processes. Equipment and chemical reagents are usually used to gauge the quality of aqua. Other quality test kits and water solutions can be used. With standard calibration of the apparatus, it is easy to get accurate and reliable findings. Listed below are some of the commonly used instruments in water testing labs.

An equipment known as BOD analyzer is normally used to find out the short-term demand for biological oxygen in wastewater. The appliance has software for ease of data management and is fitted with a control unit to help enhance the blending process in the laboratory. The gadget has an LCD screen for easy viewing of results. It also enables real time visualization of gas exchange process.

To be able to find out the chemical oxygen demand of wastewater, a COD analyzer must be used. This applies the principle of measuring UV light absorption through a high concentration of molecules. This equipment exploits the latest technology to realize reliability and speed in testing. A unique mechanism is incorporated that ensures that the temperature of the reacting solution is controlled.

In order to reduce pollution, the quality of drinking aqua should be assessed using a conductivity meter. This apparatus is also used to analyze all H2O fed into the boiler of an industry. It has an inbuilt temperature stabilization mechanism to ensure reliable findings. It is fitted with a power regulation function that helps to save power. It goes through four steps of conductivity standards and it is very easy to operate as well as cheap to acquire.

Dissolved oxygen meters are used to determine oxygen levels in aqueous solutions. Its common applications include in studying of soil respiration where the oxygen sensor is used together with carbon dioxide sensors to improve the characterization of soil respiration. This equipment is easy to calibrate, has an automatic compensation, it has an auto shut off mechanism and low battery together with consumption indicators. It also comes with a large LCD screen for displaying results.

An ion concentration meter is always used to establish the relation between two or more concentration standards. It has an inbuilt memory where it holds the information for comparison before displaying the reading. It occupies a small space as it is designed to operate from a bench top. It has features like large LCD for easy reading and enjoys structural strength for durability. Both the keyboard and display cannot be affected by water. It also has a provision for connection to a computer.

It is important to establish the alkalinity or the acidity of aqua before using it either industrially or for domestic use. To asses this, a PH meter is used. The appliance uses replaceable electrodes that are used to sense the PH of the solution. It also employs the use of microprocessor-based mechanism to generate the findings. The equipment guarantees very high accuracy levels.

Water testing labs are never complete without the availability of a toxicity analyzer. This is an important equipment for detecting the presence of aqua contaminants like hazardous chemicals or metallic substances in the aqua source. Samples of aqua in form of sediments or surface water are used to establish its purity. This appliance is easy to operate, very accurate and cheap to buy.
