Conductivity and Salinity

LAQUA F-74 pH/ORP/Ion/Cond/Res/Sal/TDS Color Touch Screen Meter

Reference
LAQUA F-74

One instrument covers pH, ORP, ion, conductivity, resistivity, salinity and TDS. The LAQUA F-74 is driven from a large capacitive color touch panel that presents values and function menus clearly, and while you measure, a single swipe moves the view between real-time digital graphs and analogue-style displays.

Help is always on screen: an electronic user guide with color pictures can be opened whenever you need it, including a troubleshooting section for calibration and measurement.
