This device reads dissolved oxygen for measuring water quality in labs, industrial and municipal waste water, fish hatcheries, and environmental testing. It features automatic temperature compensation and compensation for salt andaltitude - all factors directly affecting DO readings. Oxygen can be read in either mg/L or % oxygen in air. Both oxygen andtemperature readings are simultaneously displayed on a large LCD. Review 99 data points with time stamp, min, max, and average readings. Features one button calibration of air, and recalls last calibration.Complete with hard case, polarorographic probe, battery, spare membranes, and electrolyte. 6.75 x 2.75 x 1.25". Probe 5 x 3/4" with 4 meter cord. Weight: 14 oz.
