They r the same
There is no inherent disadvantage with a simple respirometer for what I would assume to be a teaching application. There needs to be an understanding of the difference between teaching and research. A teaching unit is a black box that gives you numbers, a research grade respirometer gives you the actual data from the analyzers. Many manufacturers of teaching and or instructional systems such as Qubit Systems market their products as research grade but they are generally recognized as being strictly for teaching.
The water inside the respirometer will decrease in volume due to the organism consuming oxygen and producing carbon dioxide. This results in a decrease in the pressure of the gas inside the respirometer, allowing the surrounding water to move up the capillary tube, indicating the rate of oxygen consumption.
A spirometer can be used to monitor a person's breathing rate and the volume of air inhaled and exhaled. For persons suffering of lung-disease or asthma, this can make a spirometer a valuable monitoring tool in regards of their specific illnesses.
Oxygen is being taken up by the germinating seeds in the respirometer. As the seeds undergo cellular respiration, they consume oxygen and release carbon dioxide, causing the volume of gas in the respirometer to decrease and the marker to move.

The syringe in a respirometer is used to adjust the volume of gas in the respirometer chamber. By pushing or pulling the plunger of the syringe, you can change the pressure inside the chamber, allowing you to measure the rate of gas exchange, such as oxygen consumption or carbon dioxide production, by the organism being studied.
The least count of a spirometer typically ranges from 1 ml to 10 ml, depending on the model and precision of the device. This value represents the smallest volume change that can be accurately measured by the spirometer.

Vital capacity is measured using a spirometer. The person takes a deep breath in and then exhales as forcefully and completely as possible into the spirometer. The spirometer records the volume of air exhaled, which is used to calculate the vital capacity.
