1. an instrument used to measure the rate of respiration or oxygen consumption in living organisms
Usage: scientific

Examples

• The scientist used a respirometer to measure the plant’s oxygen production during photosynthesis.
• Students in biology class observed how temperature affected cellular respiration using a simple respirometer.
• The respirometer showed that the germinating seeds consumed more oxygen than the dormant ones.
• Marine biologists employ underwater respirometers to study fish metabolism.
• The laboratory’s digital respirometer provided precise measurements of the organism’s breathing rate.
• Researchers calibrated the respirometer before beginning their experiment on cellular respiration.
