Equipments 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.

To be able to establish short-term demand of biological oxygen in wastewater, a BOD analyzer has to be used. They are equipped with software to manage data and a control unit to manage the blending process in the laboratory. It is equipped with a 10.4-inch touch screen, which enables easy viewing. It also provides for BOD and gaseous exchange activities to be visualized as it occurs.

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.

A conductivity meter is one important tool in checking aqua pollution. It is used to study all H2O used in industrial boilers. In order to give reliable readings, it has an in built temperature stabilization process. It is designed to draw little amounts of power because it has a power regulator option. It operates by running through four steps and it does not require specialized skills to use.

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.

To be able to tell the relation between two or more concentration standards, an Ion concentration meter has to be used. The device is fitted with an in built memory where the information is held for comparison before the reading is shown. It is designed to be used on the workbench therefore occupies a relatively small space. It has a large screen for easy reading. The key board and screen are covered with waterproof material which makes it to be very durable. The device can be attached to the computer when there is need to.

Aqua is widely used for various functions some of which are sensitive to acidity or alkalinity. A PH meter is therefore a useful apparatus for establishing the suitability of water in different situations. The gadget uses the replaceable electrodes to carry out the test in the intended solution. It also uses a microprocessor-based method to process the results. It meets a high level of accuracy requirement.

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.
