The standardization of a pH meter is important to ensure that the readings returned from that meter are accurate. Digital & analog pH meters offer calibration buttons or dials that are used to adjust the sensitivity of the meter. Over the course of standard usage, laboratory equipment, such as...
(57)< Abstract > This invention is something regarding the manner which evaluates the performance of the extinction spectrometer and the especially CO oxygen analyzer. This manner measures the absorption spectrum of the quality control sample, consists of each process which compares this with the ...
Your temperature gauge, which measures the temperature of engine coolant, will alert you to a dangerous situation. There are a host of other warning lights designed to let you know about the status of the car. Though there have been some efforts to standardize these lights in all makes ...
Insert the micropipette into a microcentrifuge tube or other container you want to transfer the liquid to. Press the tip gently against a side wall near the bottom of the container. Depress the plunger until you feel resistance, pause briefly, then press the plunger down the rest of the way....
4. Viscosimeter test. Finishing the batch On �striking the batch�, when the desired density has been reached, the condensing operation is stopped. The entire steam to the condenser is stopped and the steam to the pan is shut off. The valve in the waterline to the condenser is closed...
A pH meter will make short work of identifying the pH of your solution. These meters have a glass probe that measures a solution's ion concentration. To use a pH meter, place a small portion of your solution in a beaker or test tube, rinse the probe of the pH meter, and then place...
Ph is the relative acidity or basicity of a substance. This value is important information to have in many situations as the pH level of a substance dictates its safety, chemical reactivity and effects on the environment. Everyone from chemical engineers to home gardeners can make use of the ...
Fortunately, great strides are being made by the remote sensing community to standardize in situ measurements and protocols for robust validation of LAI [2,19]. One example is the VALERI project, which consists of a number of sites representing different biomes in Europe and part of Asia. This...
