Dissolved oxygen
Dissolved oxygen may have negative values in very low readings, such as dissolved oxygen in water below 0.05mg/l. Due to the accuracy of the sensor itself, it may be realistic -0.01,-0.02,-0.03, etc. Re-do the 0-point calibration in time. If you continue to work under very low conditions, it may still show negative values, which is normal.
