Portable Dissolved Oxygen meter - HI8043

The HI8043 is a versatile dissolved oxygen meter ideal for use in educational laboratories, wastewater treatment, fish-farming and water analysis.

  • Automatic Temperature Compensation (ATC)
  • Manual, Two-point Calibration
  • 0.01 mg/L (ppm) Dissolved Oxygen Resolution



Lightweight case, with an easy-to-read LCD

Dissolved oxygen is indicated in mg/L (ppm) with temperature compensation (ATC)

The dissolved oxygen probe is provided with a membrane to cover the polarographic sensors and a built-in thermistor

This meter can operate continuously for approximately 100 hours on one 9V battery

Low-battery warning helps reduce erroneous readings due to low power

Standby mode (stb) maintains continuous polarization so the probe is ready for use
