Description HI-9147-04 Dissolved Oxygen Meter for Fish Farming The HI-9147 is designed for aquaculture applications. This unit is unique among the Hanna 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. The HI-9147 is a must have for DO sensitive organisms or high bio-load environments.
