C4 pathway A pathway of carbon fixation, found most commonly in tropical plants that have high rates of growth and photosynthesis and that are adapted to high temperatures, strong light, low carbon dioxide levels, and low water supply. Its importance lies mainly in its reduction of photorespiration.
PT 100 RTD means Resistance temperature detector(RTD) of platinum with 100 ohms resistance at zero degree centigrade.
A platinum resistance temperature detector (RTD) is a device with a typical resistance of 100 Ï at 0 Â°C. It consists of a thin film of platinum on a plastic film.Its resistance varies with temperature and it can typically measure temperatures up to 850 Â°C. platinum resistance temperature detector (RTD) is a device with a typical resistance of 100 Ï at 0 Â°C.
