Sodium Content and Activity Portable Meter - HI931101

The HI931101 is an ion-selective sodium chloride meter that sues a sodium ion-selective electrode to measure sodium from ions 15.0 mg/L to 60 g/L pNa or % NaCl. This rugged, portable sodium content and activity meter is designed to provide laboratory precision even in harsh conditions. Ideal for a variety of applications in laboratories, food and beverage production, and water quality analysis.

  • Five Measurement Ranges
  • Automatic Calibration
  • On-Screen Instructions



Automatic calibration can be performed at one or two points with a choice of three buffers (0.23 g/L, 2.3 g/L, and 23.0 g/L)

±0.05 pNa accuracy; ±5% of reading Na

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

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

*Note: this meter does not come with the probe. Get your FC300B Sodium Combination Ion-Selective Electrode (ISE) here.
