Portable Galvanic Dissolved Oxygen Meter – HI9147

The HI9147 is a rugged, water-resistant dissolved oxygen (DO) meter designed for aquaculture applications. The meter and probe use galvanic sensor technology where the electrodes’ potential difference drives the reaction, requiring no external voltage. Oxygen diffuses across the membrane and the system establishes a current proportional to the concentration of dissolved oxygen present. HI9147 comes with a galvanic, HDPE membrane caps, electrolyte fill solution, a protective shield, and sturdy carrying case. 

  • Easily Replaceable Membrane Caps
  • Manual Calibration
  • Galvanic Measuring System
  • DIN Connector

Features

Galvanic Measuring System, requiring no external voltage

Silver cathode and zinc anode in an electrolyte solution with a polymer membrane

Automatic calibration at one or two points to 100% and/or 0% saturation

Automatic Temperature Compensation (ATC) using a high-accuracy, built-in, linearized, thermistor temperature sensor

Altitude compensation up to 4000 meters with a 100-meter resolution

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

Auto end point mode freezes a reading on the display once a stable measurement is obtained

Good Laboratory Practice allows users to recall calibration information

Replaceable, pretensioned, polytetrafluoroethylene (PTFE) membranes with a screw cap design
