HI9142 Portable Dissolved Oxygen Meter

Features

Replaceable, pretensioned, polytetrafluoroethylene (PTFE) membranes with a screw cap design for simple filling of electrolyte and easy replacement.

Polarographic measuring system based on the Ross and Clark polarographic measurement method

The probe uses a platinum cathode and silver anode in an electrolyte solution using  external voltage to establish a current proportional to the concentration of dissolved oxygen

Manual one or two point calibration at 100% and automatic calibration in zero oxygen solution

A high-accuracy, built-in linearized thermistor temperature sensor behind a stainless steel cover

All readings are automatically compensated for temperature variations
