WebMost modern sensors have good repeatability. For example, the sensor chip in Conserv's sensor has a repeatability of 0.1%, which means that if the conditions at the sensor are the same, each reading should be within 0.1% of previous readings. A sensor can have great repeatability, but poor accuracy.
