Product Description
MP511 pH Meter

1.It meets the GLP requirements of international standards and has intelligent functions such as automatic calibration, automatic temperature compensation, data storage, RS232 output, clock display, function settings, and self diagnostic information.
2.There are three different measurement modes: stable display mode; Timing measurement mode; Continuous measurement mode.
3.Automatic identification of pH standard buffer solutions, with three series of standard buffer solutions available: European and American series, NIST series, and China series.
4.Standard configuration of 201T-M three composite pH electrodes, suitable for rapid and accurate measurement of conventional aqueous solutions. pH electrode+reference electrode+temperature electrode, can simultaneously measure pH and temperature values, achieving automatic temperature compensation
5.High purity water pH measurement mode and ammonia added pure water pH measurement mode can be set. For these two special pH measurement modes, in addition to general slope temperature compensation, solution temperature is also added.
6.The degree compensation function greatly improves measurement accuracy and is particularly suitable for use in industries such as power and petrochemical.
7.There is an EH redox potential measurement mode that directly displays the ORP value relative to the standard hydrogen electrode potential.
8.Self diagnostic information to assist users in determining measurement issues.
9.Complies with IP54 dust and splash protection level, and the instrument socket is sealed with a silicone cap for protectio.
