HE-960CW, Panel-Mount Type 2-Channel Conductivity Meter, Sanitary and Pharmaceutical, HORIBA

The HE-960CW is a 2-channel panel-mount conductivity meter from HORIBA's 48/96 Series, purpose-built for pharmaceutical water quality management and sanitary process monitoring. It accepts two independent, electrically isolated conductivity sensor inputs and simultaneously monitors conductivity, TDS, temperature, desalination rate (0–100%), and conductivity difference between channels — making it ideal for reverse osmosis system monitoring, WFI loop management, and SIP/CIP phase verification. Water quality assessment is fully compliant with USP<645>, with a dedicated USP assessment alarm contact output. Four isolated 4–20 mA outputs and RS-485 support integration into pharmaceutical process automation systems. Compatible sensors include standard ESD/ESL/ESH/FS Series as well as sanitary insert and flow-through types compliant with USP and EP pharmacopoeias.

Key Features HE-960CW

• 2 independent isolated sensor input channels — simultaneous measurement at two process points with desalination rate and conductivity difference display.
• USP<645> compliant water quality assessment with dedicated alarm contact output — ideal for WFI, Purified Water, and pharmaceutical process monitoring.
• Compatible with sanitary insert sensors (ESD-01C-SN1.5, ESH-01C-SN1.5) and sanitary flow-through sensors (FS-01C-SL, FS-01FC-SL) in addition to standard ESD/ESL/ESH/FS Series.
• Four isolated 4–20 mA DC outputs (max. 900 Ω; 4–20 or 0–20 mA selectable): freely assignable to conductivity, TDS, temperature, desalination rate, or conductivity difference.
• Four relay contact outputs (R1–R3: SPST 1a; R4: SPDT 1c; 240 V AC / 30 V DC, 3 A): selectable as upper/lower limit alarm, ON/OFF control, USP assessment, anomaly alarm, or maintenance.
• RS-485 communication for SCADA/DCS integration.
• Temperature compensation: NaCl characteristic, arbitrary coefficient (±5%/°C), or none; auto deionised water compensation; range 0–100 °C.
• Panel face IP65 (IEC60529 / JIS C0920); ABS case; 96 × 96 mm DIN; Class II device IEC61010-1, Pollution Level 2.
• CE marked: EN61326-1, EN61010-1, RoHS EN50581; FCC Part 15.

Applications

The HE-960CW is suited to pharmaceutical water quality management (WFI, PW — USP<645> compliance), SIP temperature and conductivity monitoring, CIP rinse verification, reverse osmosis desalination rate monitoring, and any application requiring simultaneous dual-point conductivity measurement with pharmacopoeia-grade assessment in a panel-integrated configuration.

Installation and Safety Notes

Install into a standard 96 × 96 mm panel cutout. Power: 100–240 V AC, 50/60 Hz, 25 VA max. Panel face IP65; rear case IP20; terminals IP00 — protect the rear from moisture. Operating temperature −5 to 55 °C; storage −25 to 65 °C; humidity 20–85% RH non-condensing.
