This manual provides instruction for use of the HI 98402 Waterproof and Accurate Fluoride Meter, including product features, specifications, operational guide, calibration, temperature calibration, electrode maintenance, battery replacement, accessories, warranty, and CE Declaration of Conformity.
The Hanna HI-98402 is a microprocessor-controlled instrument designed to measure fluoride concentration from 0.05 mg/L to 1.9 g/L with automatic ranging capabilities. It features a large LCD display that simultaneously shows fluoride concentration and temperature (when using the optional HI 7662 probe), ensuring maximum repeatability through compensation for temperatures between 5°C and 35°C.
| Range | 0.050 to 1.90 g/L in 5 distinct scales |
|---|---|
| Resolution | 0.001 mg/L (ppm) / 0.01 mg/L / 0.1 mg/L / 1 mg/L / 0.01 g/L Fluoride |
| Accuracy | ±5% of reading or ±0.02 ppm Fluoride (with ±3°C from calibration temperature) |
| Battery Life | approx. 120 hours of continuous operation |
| Dimensions | 196 x 80 x 60 mm (7.7 x 3.1 x 2.4") |
The meter measures fluoride from 0.05 mg/L to 1.9 g/L in 5 distinct scales.
Yes, with auto-ranging the instrument automatically selects the range that provides the best resolution.
The meter requires the HI 4010 fluoride specific electrode and a separate HI 5313 reference electrode.
The text recommends frequent calibration but does not specify a fixed duration for the process itself.
