This dissolved oxygen meter is a rugged, portable, waterproof dissolved oxygen (DO) meter designed to provide reliable measurements under harsh environmental conditions.

• Easily replaceable membrane caps
• Manual calibration, at one or two points (zero and slope)
• Waterproof

Replaceable membrane caps - The pretensioned polytetrafluoroethylene (PTFE) membranes employ a screw cap design for simple filling of electrolyte and easy replacement on the probe.

One or two point calibration - Calibration for this meter is performed as a manual calibration at 100% and automatic calibration in zero oxygen solution.

Polarographic measuring system - The meter and probe use polarographic sensor technology based on the Ross and Clark polarographic measurement method. The probe is comprised of a platinum cathode and silver anode in an electrolyte solution held in place over the surfaces of the electrodes by a polymer membrane. An external voltage applied across the system establishes a current proportional to the concentration of dissolved oxygen.

The dissolved oxygen is a durable, waterproof dissolved oxygen (DO) meter designed to provide reliable measurements under harsh environmental conditions. The meter features manual calibration at 100% and automatic calibration in zero oxygen solution. This meter includes a polarographic probe with replaceable polytetrafluoroethylene (PTFE) membrane caps and protective shield. The rugged, waterproof housing of the meter solves many of the problems with frequent field use.
