430
Part code: 430 271
Enterprise Conductivity/pH Meter
The easy to use 430 is designed to readily withstand the rigours
of field work, while reliably measuring pH and conductivity. The
unit allows the simultaneous readout of pH, conductivity or TDS
and temperature with switched ranges for both conductivity and
TDS measurements.
