HI9147 Portable Dissolved Oxygen Meter

The HI9147 is a rugged and water-resistant dissolved oxygen (DO) meter, engineered to deliver accurate and precise measurements in demanding environmental conditions. This meter is well-suited for a variety of applications, including aquaculture, wastewater treatment, environmental monitoring, and wine analysis. It features manual one-point calibration, automatic temperature compensation, and both salinity and altitude compensation. The HI9147 includes a galvanic probe, replaceable high-density polyethylene (HDPE) membrane caps, and a protective shield, providing a complete solution for reliable DO measurement. Its salinity compensation feature makes it particularly valuable in aquaculture settings.

Key Features

Replaceable Membrane Caps: The pre-tensioned HDPE membranes feature a user-friendly screw cap design, allowing for quick and easy replacement by simply filling them with HI7042 electrolyte solution and attaching them to the DO probe.
Galvanic Measuring System: The meter and probe utilize galvanic sensor technology, where the potential difference between the electrodes drives the measurement, eliminating the need for an external voltage source. The probe consists of a silver cathode and zinc anode within an electrolyte solution, contained by a polymer membrane. Oxygen diffuses through the membrane, generating a current proportional to the dissolved oxygen concentration.
Automatic Temperature Compensation: All readings are automatically compensated for temperature variations using a highly accurate, built-in linearized thermistor temperature sensor protected by a stainless steel cover.
Altitude Compensation: The HI9147 provides altitude compensation, adjustable 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, enabling accurate DO measurement in brackish water and seawater.
Backlit LCD: The HI9147 features a backlit display, ensuring clear visibility of readings even in dimly lit environments.
