LAQUA F-74

Benchtop pH/ORP/Ion/Conductivity/Resistivity/Total Dissolved Solids/Salinity/Temperature Meter

Stress-free measurement, high-end model

Water quality analysis is repeatedly performed in laboratories on a daily basis. Our high-end benchtop model was developed to provide simplicity with excellent on-site usability - from operation and maintenance through to troubleshooting.

LAQUA’s large capacitance touch screen panel:

• Display easy to understand value and functions menus
• Switch between digital real time graphs or analogue displays during measurement with just flick of a finger
• Full on-screen support on the meter via an electronic user guide with colour pictures that can be called up at any time, featuring problem solver guide for calibration or measurement

LAQUA F-74 Key Functions:
