mp526 conductivity/do meter
    for high-precision measurements of the conductivity and dissolved oxygen in laboratory. suitable for biotechnology, aquaculture, power plants and environmental protection industries.

●meter meets with the requirement of international glp standards. its features up to automatic calibration, automatic temperature compensation, data storage, timing measurement, clock display, rs-232 output, function setting and self-diagnose etc.

● there are three different measurement modes: stable display mode; time measurement mode; continuous measurement mode.
●automatically recognize 8 kinds of conductivity standard solution. user can choose anyone from two series of solutions: europe & usa series and china series.
● adopt advanced and original conductivity measurement technology, use 1 pc of conductivity electrode (k=1), it can meet measuring accuracy requirement for range within 0.5μs/cm ~ 200ms/cm by using only one-point calibration.
● ability to switch among conductivity, tds, salinity and resistivity. multinomial calculation for tds and salinity to ensure the conversion precision of the full scale.
● conductivity measurement mode has the function of non-linear temperature compensation for high purity water.
● equips new type of do electrode which has function of automatic temperature compensation and automatic salinity compensation as well as automatic air pressure compensation inside meter to make do measuring mode has temperature, air pressure and salinity automatic compensation, easy to use, accurate to measure.
● polarogram type do electrode has special electrode calibration cap. only needs 3 to 5 minutes for electrode polarization. electrode adopts combination diaphragm cap which very convenient to use. each do electrode equips with three spare diaphragms caps.
● meter has the only product serial number.
● dustproof and waterproof meter meets ip54 standards. all sockets are seal protected by the silica gel caps.
