HI 931100

Salinity and Sodium Content Measurement Meter
I 931100 is an ion-selective meter that uses a sodium electrode to read the salt (NaCl) content of a solution. This powerful instrument has four ranges, capable of measuring concentrations from 0.150 g/L to 300 g/L.

HI 931100 auto ranges from sample to sample over an extremely broad range without the need for recalibration.

A separate temperature probe, HI 7662, provides temperature readings from -20 to 120°C.
