GENERAL DESCRIPTION

HI 98402 measures fluoride from 0.05 mg/L to 1.9 g/L in 5 distinct
scales. With auto-ranging HI 98402 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 HI 4010 fluoride specific
electrode and the separate HI 5313 reference electrode.

HI 98402 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 dis­played 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 calibration points can be chosen among 1 mg/L (ppm), 2 mg/L,
10 mg/L, 100 mg/L and 1000 mg/L.

HI 98402 is supplied in a rugged carrying casing complete with 4
batteries, that provide up to 120 hours of continuous operation.
