Features at a Glance

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.
