A handheld turbidity meter measures turbidity of a water sample. The meter is calibrated using standard samples from the meter manufacturer. The picture with the three glass vials shows turbidity standards of 5, 50, and 500 NTUs. Once the meter is calibrated to correctly read these standards, the turbidity of a water sample can be taken.

A thermometer measures the temperature of boiling water, while a stopwatch measures the time it takes for water to boil. These two instruments can be used together to calculate the rate at which water boils.
A hygrometer is a weather instrument that measures moisture in the atmosphere. It quantifies the amount of water vapor present in the air to provide information about humidity levels.
No, the pH level and alkalinity are not equivalent in water quality testing. pH measures the acidity or basicity of water, while alkalinity measures the water's ability to resist changes in pH.
This instrument is a balance.
An instrument that measures heat and cold is called a thermometer.
