MP-2006 multi-parameter analyzer (hereafter refers to meter) is a new laboratory analyzer which
contains ion measuring part, conductive measuring part, dissolved oxygen measuring part and
temperature measuring part. It allows inspecting the relevant parameters of above parts. It also
allows users to select individual parameter for measuring according to the practical needs. In which
ion measuring part allows to measure: potential value, pH value (or pX value) and ion concentration.
Conductive measuring part can measure: conductivity, resistivity, TDS and salinity. Dissolved
oxygen measuring part can measure: electrode current, concentration of dissolved oxygen and
saturation of dissolved oxygen. Temperature measuring part can measure temperature value of
present solution.
The meter has following character:
A．Ion Measuring Part
a. To measure Potential value, pH value (or pX value) and ion Concentration.
b. To measure several general ions. Meter provides several general ion modes: H

selective electrode and reference electrode to measure corresponding ion concentration directly.
When measuring finishes, use can easily read the concentration between different concentration
units.
c. Apart from the ion part provided by the meter, in case you need to measure other ion, you can
also set your own ion mode to measure other ion.
d. Meter has the ability of automatic recognition standard buffer solution. You can select several pH
standard buffer solutions to calibrate electrode. Total 10 different standard buffers are provided.
e. Set own standard solution groups.
f. With one-point, two-points and multiple-points calibration (mostly 5 points) function.
g. With several concentration measuring modes: Direct Reading concentration measuring mode,
Known Addition measuring mode, Sample Addition measuring mode and GRAN Method
measuring mode.
h. On the basis of high speed micro-processor, with high precision A/D, matched with precise
measuring electrode, meter can ensure the high precision. The valid resolution of potential can be
reached to 0.01mV.
B．Conductive Measuring Part
a. Meter can measure Conductivity, Resistivity, Total Dissolved Solid (TDS) and Salinity.
b. Within full measuring range, meter has automatic temperature compensation, automatic
calibration, automatic measuring range and automatic frequency switching functions.
c. With calibration function. User could calibrate Cell Constant or TDS Factor.
