RS232 to USB Adaptor Cable, 840094
 (for use with RS232 cable: converts 9-pin plug to USB)
 $20

Reads dissolved oxygen for measuring water quality in labs, industrial and municipal waste water, aquariums, fish hatcheries, and environmental testing. Also monitors oxygen in air for indoor air quality and confined space applications.   Features automatic temperature compensation as well as compensation for salt and altitude, all factors that directly effect D.O. readings.   Simple one button calibration to air.   Oxygen can be read in either mg/L or % oxygen in air, and temperature in °C or °F.   Both oxygen and temperature readings are simultaneously displayed.   

Features min-max-average, RS-232 port, large LCD with unique LCD viewing angle contrast control, Auto Power Off, hold, low battery, and over range indicators.  Heavy duty but light weight construction perfect for field use. Comes in a hard carrying case complete with a polarographic probe with a built in temperature sensor, battery, spare membranes, and electrolyte.
