The Hanna Instruments HI 9147 Dissolved Oxygen Meter for Aquaculture with Probe is designed for aquaculture applications. However, the Hanna Instruments HI9147 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 the user needs to measure multiple samples in a given period of time, pick it up and measure on demand. The Hanna Instruments HI 9147 is a must have for DO sensitive organisms or high bio-load environments.

Features:

• Replaceable Membrane Caps - The pretensioned high-density polyethylene (HDPE) membranes employ a screw cap design that can be changed quickly by simply filling with the HI7042 electrolyte fill solution and screwing onto the DO probe.

• Galvanic Measuring System - The meter and probe use galvanic sensor technology where the electrodes’ potential difference drives the reaction, requiring no external voltage. The probe is comprised of a silver cathode and zinc anode in an electrolyte solution held in place over the surface of the electrodes by a polymer membrane. Oxygen diffuses across the membrane and the system establishes a current proportional to the concentration of dissolved oxygen present.

• Automatic Temperature Compensation - All readings are automatically compensated for temperature variations with a high accuracy, built-in linearized thermistor temperature sensor behind a stainless steel cover.

• Altitude Compensation - The HI9147 allows for altitude compensation for up to 4000 meters with a 100-meter resolution.

• Salinity Compensation - Salinity compensation is adjustable from 0 to 51 g/L (ppt) with a 1 g/L resolution for the measurement of DO in brackish and sea water.

• Backlit LCD - The HI9147 has a display with a backlight for easy viewing of readings in poor lighting conditions.
