Elcometer 138 Bresle Salt Meter

Incorporating a flat sensor, the Elcometer 138 Bresle Salt Meter measures the conductivity of a sample, then automatically converts this to show the density of salts, negating the need for the user to do a manual calculation when working in accordance with ISO 8502-6 or ISO 8502-9.

The Elcometer 138 Bresle Salt Meter features:

  • Highly precise measurements can be obtained
  • Out of range and low battery alarms
  • Visual indication when ambient temperature is outside the operating range
  • Elcometer-138-Bresle-Salt-Meter
