Salinity and Sodium Content Portable Meter - HI931100

The HI931100 is an ion-selective sodium chloride meter that uses a sodium ion-selective electrode to measure the salinity content of a solution in four concentrations spanning 0.150 g/L to 300 g/L (NaCl). This meter is ideal for a variety of applications in laboratories, food and beverage production, and water quality analysis and comes loaded with features.

  • On screen instructions
  • Auto-ranging from sample to sample
  • Automatic one or two point calibration



Automatic calibration can be performed at 1 or 2 points with a choice of 3 buffers (0.30 g/L, 3.00 g/L, and 30.0 g/L)

Step-by-step on-screen instructions to perform calibrations and measurements

The HI931100 should be used with the FC300B (not included) sodium ion-selective electrode

Fixed temperature compensation of sodium measurements at 25℃

BNC probe input for connecting the sodium ISE

RCA connector for a thermistor temperature probe
