Fluorine Meter HI98402

Fluorine Meter HI98402 Ion Selective Electrodes (ISE) Water / Liquid Analysis

Add Quotation

  • Tutorial messages on LCD display
  • Direct measurements in mg/L or g/L
  • Waterproof, rugged housing for indoor/outdoor applications
  • Extensive fluoride scale
  • Automatic Temperature Compensation

HI 98402 measures fluoride from 0.05 mg/L to 1.9 g/L in 5 distinct scales. With autoranging, HI 98402 automatically selects the range that provides the best resolution.

HI 98402 automatically compensates for temperature from -5 to 55°C using the optional HI 7662 stainless steel temperature probe. Both the temperature measured together with fluoride concentrations are displayed on the large LCD.

Calibration is automatic at 1 or two points. The calibration points can be chosen among 1 mg/L, 2 mg/L, 10 mg/L, 100 mg/L and 1000 mg/L.

HI 98402 is supplied in a rugged carrying case complete with batteries that provide up to 200 hours of continuous operation.
