Model FDW-0871 -Portable Dissolved Oxygen Meter

FromChangsha Friend Experimental Analysis Instrument Co.,Ltd

SHARE

Fully watertight (IP67 waterproof rating), impact resistant instrument housing, and innovative dissolved oxygen electrode modules that can be replaced in the field. Dissolved oxygen and temperature can be measured simultaneously using YSI`s proven polarography technology and YSI`s global high-precision temperature model of thermistor technology. The new generation PE cover film provides faster reaction times and lower agitation dependence.
