2.2 General product information
The MP-4, MP-6 and MP-6p (see Figure 2 on page 14) handheld meters allow
users to test water for pH, ORP, conductivity, resistivity, TDS (Total Dissolved
Solids), mineral/salt concentration and temperature.
2.2.1 Overview
The MP Series portable meters measure various parameters in water. Data can be
stored and (with the optional MP-Dock) transferred to a printer, PC, or USB storage
device.
•MP-4—Measures conductivity, resistivity, TDS and temperature
•MP-6p—Measures pH, ORP, conductivity, mineral/salt concentration, TDS and
temperature. The mineral/salt measurement is a TDS value based on an NaCl
profile.
•MP-6—Measures pH, ORP, conductivity, resistivity, TDS and temperature
