Economical portable trace dissolved oxygen analyzer

BOLOR quality providesGTOX-800 portable trace dissolved oxygen analyzer is economical, easy to carry, and accurate in testing, produced by GeneTestperformancereliable.

Product Introduction

The GTOX-800 portable trace oxygen analyzer is an economical, high-performance portable instrument. The sensor electrode adopts the principle of polarographic high current electrode and uses a high-performance oxygen permeable membrane, which has good stability, sensitivity, and measurement accuracy. The electrode zero drift is small (≤ 2ug/L), residual current is small, response speed is fast, service life is long, and maintenance is simple. It is a specialized analyzer for detecting trace dissolved oxygen in water such as boiler feedwater, condensate water, and deaerator outlet water.

Instrument principle:

The instrument adopts a polarography sensor, with gold and silver as cathodes and anodes in the electrodes. Filled with electrolyte. The outer surface of the cathode is covered with an oxygen permeable film. Apply polarization voltage between the anode and cathode electrodes. When dissolved oxygen passes through the film and reaches the surface of the gold cathode, the following reaction occurs on the electrode:

Cathode is reduced: O2+H2O+4e → 4OH-
Anodizing: 4Cl -+4Ag-4e → 4AgCl

Under normal circumstances, the diffusion current generated by the aforementioned reduction oxidation reaction is directly proportional to the concentration of dissolved oxygen. Therefore, it can be seen that the oxygen electrode converts the oxygen concentration into an electrical signal, which is then amplified, adjusted, and designed for calculation, and presented on the display screen.
To eliminate the influence of temperature and pressure factors, the electrode is equipped with a built-in temperature sensor, and the instrument can manually input pressure values to automatically compensate for the impact of temperature and pressure on measurement.
