HANNA HI9147 Portable Dissolved Oxygen Meter

HI 9147 is designed for aquaculture applications. This unit is unique among our family of DO meters as it is supplied with a galvanic probe.
Unlike polarographic probes, galvanic DO probes require no conditioning time. When you need to measure multiple samples in a given period of time, pick it up and measure on demand.
HI 9147 is a must have for DO sensitive organisms or high bio-load environments.
