The meter is a rugged, portable, waterproof dissolved oxygen (DO) meter designed to provide reliable measurements under harsh environmental conditions. The meter features manual calibration and an auto-off function. The unit is supplied complete with polarographic probe, PTFE membrane caps, electrolyte fill solution, protective shield, and rugged carrying case.
- Easily Replaceable Membrane Caps
- One or Two Point Calibration
- Waterproof
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.
