Hanna Instruments HI 98401 User Manual

Page 3

HI 98401 measures fluoride from 0.05 mg/L to 1.9 g/L in 5 distinct
scales. With auto-ranging HI 98401 automatically selects the range
that provides the best resolution. All results are displayed directly in
fluoride concentration. In order to guarantee maximum repeatability,
measurements are performed using the FC 301B fluoride specific
electrode and the separate HI 5313 reference electrode.

HI 98401 compensates for temperature automatically from 5 to 35°C
using the optional HI 7662 stainless steel temperature probe. The
temperature measured together with fluoride concentrations are dis-
played on the large LCD simultaneously.

All operations are microprocessor controlled for added precision and
simplicity. The calibration is automatic at one or two points. The first
calibration point is in the middle of the range at 100 mg/L (ppm). The
slope can then be selected for low fluoride measurements at 10 mg/L,
or higher contents at 1000 mg/L.

HI 98401 is supplied in a rugged carrying casing complete with 4
batteries, that provide up to 120 hours of continuous operation.
