HANNA® has designed this rugged waterproof salinity and sodium meter for regular use in the lab, as well as in harsh processing environments.

HI 931101 employs FC 300B combination sodium electrode (not included) to give you sodium readings from 15.0 mg/L to 60 g/L. The calibration process is automatic at 2 points, the first is at 2.3 g/L while the second can be either at 0.23 g/L (low range) or at 23.0 g/L (high range).

A separate temperature probe, HI 7662, provides temperature readings from 0 to 80°C.

• Measures 4 NaCl ranges
  
• Displays parameter and temperrature readings simultaneously
