[Chemical Knowledge]：What is the range

This is a common question, especially when it comes to measuring instruments. In this article, we will explore what measuring range is and its significance in practical applications.

range refers to the range of values that an instrument or sensor can measure. In other words, it is the scale range of values between the minimum and maximum values that the instrument is capable of measuring. For example, if a temperature sensor has a range of -20 to 100 degrees Celsius, the sensor may measure any temperature value from -20 to 100 degrees Celsius. If the range of the temperature sensor is 0 to 100 degrees Celsius, the sensor can only measure any temperature value from 0 to 100 degrees Celsius.

In practical applications, the range is particularly important. For example, if you are buying a pH test instrument, you need to determine whether the measuring range of the test instrument is suitable for your needs. Assuming that you only need to measure the pH of water, then you do not need to buy a pH instrument with a range of 0-14, because the pH value of water generally ranges between 6-8. Instead, you may only need to buy a 5-9 pH test instrument.

Factors to consider for determining the range include the type of quantity to be measured, the expected minimum and maximum values, and the common range. For example, for a medical thermometer, the range should be from 90 to 110 degrees Fahrenheit. This would cover the vast majority of the body temperature range without wasting resources too much.

In the daily use of measuring instruments, the correct range can ensure the accuracy and reliability of the instrument. If the range is set too low, it will result in reduced accuracy because the sensor is operating at the edge of the upper limit it can measure. Conversely, if the span is set too high, the accuracy of the measurement will be lost. In this case, it is best to choose a larger measurement range to ensure the accuracy of the measurement data.

range refers to the range of values that a measuring instrument or sensor can measure. In practical applications, the correct range can not only ensure the accuracy of the measurement data, but also ensure the accuracy and reliability of the measuring instrument. Therefore, when purchasing a measuring instrument, it is important to ensure that the correct range is selected to suit your application.
