The HE-960HI is a 96 × 96 mm DIN panel-mount conductivity meter from HORIBA's 48/96 Series, designed for advanced concentration control in food and beverage production lines, CIP/SIP processes, and high-conductivity industrial applications. Using the 4-electrode method with sanitary FES-2XX and FES-310 Series sensors (smooth, crevice-free design; cell constant 0.1 /cm), it measures conductivity up to 500 mS/cm and provides built-in concentration conversion for HNO₃, NaOH, H₃PO₄, and two user-defined chemical curves. Four isolated 4–20 mA outputs, five relay contacts, two contact inputs with range switching, and RS-485 deliver a comprehensive output suite for demanding process automation.

The HE-960HI is a panel-mount conductivity meter from HORIBA's 48/96 Series, engineered for advanced concentration control in food and beverage manufacturing, CIP/SIP processes, and high-conductivity industrial applications. It is designed exclusively for use with HORIBA's sanitary FES-2XX (submersible insertion) and FES-310 (flow-through inline) Series sensors — smooth-surfaced, crevice-free 4-electrode sensors rated for high-pressure and high-temperature conditions that are stain-resistant and easy to clean. Conductivity is measured up to 500 mS/cm with built-in concentration conversion for three pre-programmed chemicals (HNO₃, NaOH, H₃PO₄) and two fully user-defined curves. Four isolated 4–20 mA outputs, five relay contacts, two contact inputs for remote range switching, and RS-485 make the HE-960HI a fully featured concentration controller for demanding hygienic process environments.
Key Features HE-960HI
- Sanitary 4-electrode FES-2XX and FES-310 Series sensors (cell const. 0.1 /cm) — smooth, crevice-free design rated for CIP/SIP high-pressure and high-temperature conditions.
- Conductivity up to 200 mS/cm (temperature compensated) / 500 mS/cm (uncompensated); four sub-ranges: 0–2, 0–20, 0–200, 0–500 mS/cm.
- Built-in concentration conversion: HNO₃, NaOH, H₃PO₄ (each 0–5%, pre-programmed); Option 1 and 2 user-defined curves (0–100%, user-set temperature compensation and conversion formula).
- Four isolated 4–20 mA DC outputs (max. 900 Ω); Cur4 output switchable via external contact input for multi-range concentration monitoring.
- Five relay contact outputs: R1–R4 (SPST 1a, 240 V AC / 30 V DC, 1 A) — upper/lower alarm, ON/OFF control; RF (SPDT 1c, 240 V AC / 30 V DC, 1 A) — error/anomaly alarm or maintenance.
- Two contact inputs: configurable as 4-range selection or 2-range selection + hold.
- RS-485 communication for SCADA/DCS integration.
- Temperature compensation: NaCl (ref. 25 °C), arbitrary coefficient (0–5%/°C, ref. 25 °C), or none; Pt 1 kΩ; range 0–100 °C.
- Panel face IP65 (IEC60529 / JIS C0920); 96 × 96 mm DIN; ABS case; Class II device IEC61010-1, Pollution Level 2.
- CE marked: EN61326-2-3, EN61010-1; FCC Part 15.
Applications
The HE-960HI is suited to chemical concentration control in food and beverage production lines (CIP/SIP phase monitoring), industrial process concentration management (NaOH, HNO₃, H₃PO₄ and custom chemicals), high-conductivity wastewater treatment, and any application requiring sanitary sensor compatibility with advanced multi-output concentration monitoring.
