MP525 pH/Dissolved Oxygen Tester
The MP525 pH/Dissolved Oxygen Tester is a laboratory-grade high-precision benchtop electrochemical instrument. It boasts a wide
range of applications, and is particularly suitable for industries such as biotechnology, aquaculture, power plants, and environmental protection. It also delivers outstanding performance in the fields of education and scientific research.
Features
It complies with GLP requirements in line with international standards and is equipped with such intelligent functions as
automatic calibration, automatic temperature compensation, data storage, RS232 output, clock display, function setting, and self-diagnostic information.
By adopting digital filtering and slip technology, the instrument intelligently improves the response speed of the meter and the accuracy of measurement data, and displays a smiley icon when the measured value is stable.
It automatically identifies 13 types of pH standard buffer solutions, with four series of standard buffer solutions available for selection: European & American series, NIST series, Chinese series, and custom solutions.
It comes standard with a 201T-M plastic-housed pH/ATC triple-combination electrode, a LabSen211 glass pH combination electrode, an MP500 temperature electrode, and a DO500 dissolved oxygen electrode.
It can be set to high-purity water pH measurement mode and ammonia-added pure water pH measurement mode. For these two special pH measurement modes, in addition to the general slope temperature compensation, a solution temperature compensation function is added—greatly improving measurement accuracy and making it particularly suitable for industries such as electric power and petrochemicals.
It features an EH redox potential measurement mode, which directly displays the ORP value relative to the potential of the
standard hydrogen electrode (SHE).
It comes standard with a patented 3-in-1 polarographic dissolved oxygen electrode. This electrode supports automatic temperature compensation and automatic salinity compensation, along with manual atmospheric pressure compensation—ensuring easier operation and more accurate measurement.
For the polarographic dissolved oxygen electrode, when used with the dedicated dissolved oxygen electrode calibration sleeve, electrode polarization takes only 3–5 minutes.
The electrode adopts a combined diaphragm cap, where the sensitive membrane and the diaphragm cap housing are integrated. When replacing the sensitive membrane, you only need to screw a new diaphragm cap onto the electrode, making operation extremely convenient. Each dissolved oxygen electrode is equipped with three spare diaphragm caps.
The instrument meets the IP54 dust and splash protection rating, and all interfaces are sealed and protected with silicone caps.
