The HC-300F is HORIBA's field-installation type fluoride ion concentration meter, designed for continuous monitoring of free fluoride ions in wastewater from semiconductor and FPD manufacturing plants and glass factories. Based on the ion selective electrode method with the fluoride ion electrode 1009A (lanthanum fluoride response film), it covers a wide range from 0 to 10,000 mg/L F⁻ across 10 selectable preset ranges. The 2-wire loop-powered design (24 V DC, 0.6 W) requires no separate AC supply. IP65 aluminium housing; pole or wall mount; CE marked (EN61326-1, RoHS EN50581); FCC Part 15 Class A.

The HC-300F is HORIBA's field-installation type fluoride ion concentration meter, designed for continuous monitoring and management of fluoride wastewater from semiconductor and FPD manufacturing plants and glass factories. It uses the ion selective electrode method with the fluoride ion electrode 1009A, which incorporates a lanthanum fluoride (LaF₃) response film and an Ag/AgCl reference electrode with KCl internal solution — detecting free fluoride ions (F⁻) directly in the sample. A wide measurement range of 0–10,000 mg/L F⁻ with 10 selectable preset ranges allows the instrument to cover both low-concentration environmental monitoring and high-concentration process wastewater management with a single unit. The 2-wire loop-powered design (24 V DC, 0.6 W max.) draws operating power directly from the 4–20 mA signal loop, eliminating the need for a separate AC supply and simplifying installation. A comprehensive lineup of immersion and inline holders, as well as immersion and circulation water-jet cleaning devices, supports deployment in a wide variety of installation configurations.
Key Features HC-300F
- Wide fluoride ion measurement range: 0–10,000 mg/L F⁻ with 10 selectable preset ranges (10, 20, 50, 100, 200, 500, 1000, 2000, 5000, 10000 mg/L) — single unit covers low to high concentration applications.
- Fluoride ion electrode 1009A: lanthanum fluoride response film; Ag/AgCl reference (KCl 3.3 mol/L, replenishment type); ceramic double junction; Pt1000 temperature compensation; submersible design; 5 m cable.
- 2-wire loop-powered: 24 V DC, 0.6 W max. — no separate AC supply required; simplified installation and retrofitting.
- Single isolated 4–20 mA DC output (max. 600 Ω at 24 V DC, voltage-dependent); free range setting; hold and burnout options.
- 1/2-point calibration with automatic detection of calibration failure (asymmetry potential, sensitivity, response time); calibration history stored.
- Self-diagnostics: calibration errors, electrode temperature sensor short-circuit/disconnection, CPU/ADC/memory errors.
- Diverse lineup of holders (CH-10 immersion, CF-30 inline) and cleaning devices (JCH-12 immersion water-jet, JCH-32 circulation water-jet).
- IP65 (IEC60529 / JIS C0920); pole (50 A) or wall mount; aluminium alloy housing; SUS304 fittings and hood; −20 to 60 °C.
- CE marked: EN61326-1, RoHS EN50581; FCC Part 15 Class A.
Applications
The HC-300F is suited to continuous fluoride ion monitoring in wastewater treatment systems at semiconductor manufacturing plants, FPD (flat panel display) factories, and glass production facilities — particularly for managing fluoride discharge concentrations against regulatory limits. It is also applicable to general industrial process water where continuous free F⁻ monitoring is required.
Installation and Safety Notes
Power from a 24 V DC source (21–32 V DC) via the 4–20 mA loop. Maximum load resistance depends on supply voltage — consult the load curve. When sensor, transmission, or contact input cables are extended to 30 m or more, the CE marking surge test does not apply — fit appropriate surge absorption elements. An internal arrester (spark-over voltage 400 V) is provided for the transmission output terminal. Sample conditions: pH 4–12 (concentration-dependent); conductivity ≥500 μS/cm; temperature 0–40 °C; flow rate 1–20 cm/s. Note: this meter detects free fluoride ions only; fluoride complexes are not detected and will result in readings lower than JIS total fluoride values. Operating temperature: −20 to 60 °C; humidity: 5–90% RH non-condensing.
