A pH meter must be standardized because it measures relative potentials and thus relative pH. It is necessary to know to what the measurement is relative. A standard must be measured and the meter set to the known value for this standard. The pH values of other solutions are then measured relative to this standard.

What is the difference between a universal indicator and a pH meter?
A pH meter is an ion selective electrode (H+), it gives pH to a far more accurate figure and leaves no room for interpretation (based on wetness of strip, colour may appear to show different pHs with univ. indicator
Why is it necessary to adjust pH ofthe nutrient broth?
Life works at physiological pH and temperature. pH is the measure of concentration of hydrogen ion in a buffer that regulate the alkaline and acidic nature. High alkaline pH or acidic pH are not suitable for all bacteria to survive and grow. Hence we need to check the pH of any media.
What are two ways scientists can measure pH?
Sorry, but there is only one solution. However, there are two ways to make these solutions. First you find the pH of either using litmus paper taht either turns red or blue indicating an acid or a base. Secondly, you can make your own natural pH indicator using red cabbage or blueberry. [[User:Bowler225|Bowler225]] 16:41, 18 Mar 2009 (UTC) There are many indicators. They change color at set pHs, which is known as the "transition range." Common indicators are Bromothymol Blue, Bromocresol Blue, Phenolphthalein and Methyl Orange.
What scientific equipment would most directly help increase the accuracy and decrease the bias in an experiment?
For example is a pH-meter.
What are needed for the seed germination?
The conditions necessary for seed germination include:optimum temperature,oxygen,adequate supply of water,sunlight,moisture content,soil ph......
How you standardize pH meter?
Standardize the pH meter using a buffer solution of known pH value.Basically take buffer of pH value 4.Then set zero reading in the pH meter.Now remove unknown buffer solution.(take care with atmospheric temperature.)
Function of pH meter?
A pH meter measures the pH of a solution utilizing a glass electrode and a voltmeter.
How do we find out the pH?
The pH is determined with a pH-meter.
Which electrode is used in pH meter?
Combine electrod used in ph meter
How can a pH meter help you?
A pH meter shows how acidic or basic a substance is
How can a person distinguish among acids bases and neutral substances?
With a pH meter or pH paper. Other indicator dyes (e.g. litmus, phenolphthalein) may be used if it is not necessary to determine the exact numerical pH value.
What is the use of a pH Meter in the laboratory?
A pH meter determines acidity or alkalinity of a substance.
How do you measure pH without a pH meter?
We can use a pH paper.
Can you find the pH of a substance with a thermometer?
The pH is determined with a pH-meter.
How do you get the pH up in a lagoon?
You need a pH-paper or a pH-meter.
What are 3 methods to measure pH?
pH indicator, pH paper, and a pH meter. You can find them on this page http://onsager.bd.psu.edu/halmi/chem3pHS05.pdf
What is the best method to use to determine the pH of a solution?
Using a calibrated pH-meter with correction for temperature and slope.
