Hanna Instruments hi 98401 ユーザーズマニュアル

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 (F

-----

) concentration. In order to guarantee maximum repeat-

ability, the measurements are performed utilizing, the optional 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 mensured 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 comes in a rugged waterproof casing so that measurements
may be performed indoors as well as outdoors. Four common AA type

batteries provide up to 120 hours of continuous operation.
