HI9142 Waterproof Dissolved Oxygen Meter

The HI9142 is engineered for reliable dissolved oxygen (DO) measurements, even in harsh conditions. Its durable, waterproof design makes it ideal for field use. This meter features straightforward manual calibration at 100% saturation and automatic calibration in zero oxygen solution. The HI9142 system includes a polarographic DO probe, which utilizes replaceable PTFE membrane caps, and a protective shield, ensuring longevity and accuracy.

Key Features

  • Replaceable Membrane Caps: PTFE membranes with a user-friendly screw cap design simplify electrolyte filling and membrane replacement on the polarographic probe.
  • Polarographic Measurement: Employs the Ross and Clark polarographic method, using a platinum cathode and silver anode in an electrolyte solution, with an applied voltage generating a current proportional to DO concentration.
  • One or Two-Point Calibration: Offers both manual calibration at 100% saturation and automatic calibration in zero oxygen solution.
  • Automatic Temperature Compensation: Compensates for temperature's effect on oxygen solubility and membrane permeability, using a high-accuracy, built-in linearized thermistor temperature sensor with a stainless steel cover.
