Product details
Hex-Body 2-Electrode Conductivity Sensor with PG Cable Gland
The InstroDirect IDC-2W-SS-H Hex-Body Stainless 2-Electrode Conductivity Sensor is a heavy-duty two-electrode conductivity probe with a solid 316 stainless hex body and PG cable gland for panel-mounted industrial installations. Rated to 100 °C and 10 bar, it suits process water, cooling loops, and boiler feedwater where vibration and thermal cycling are routine.

Why Integrators Choose the IDC-2W-SS-H
- Solid stainless hex body tightens into a pipe boss with a standard spanner
- PG9 cable gland ensures IP68 sealing even in wash-down environments
- 10 bar pressure rating covers most industrial process lines
- RS485 Modbus drops directly into PLC systems
- Integrated Pt1000 means one cable handles both conductivity and temperature
Installation & Calibration Notes
Pipe boss welded or threaded to 3/4″ NPT or G3/4. Torque with a spanner to 25 Nm — do not over-tighten.
Frequently Asked Questions
What is the maximum cable run length on RS485?
Up to 1000 m on shielded twisted-pair cable at 9600 bps, and up to 300 m at 115200 bps. For longer runs use a Modbus TCP gateway.
Can the cable be cut or spliced?
We do not recommend field splicing RS485 shielded cable — it degrades signal integrity. Order the cable length you need (5 m, 10 m, 20 m, or 50 m).
Is this rated for drinking water contact?
The 316 stainless and FKM materials are WRAS-equivalent grade. For AU drinking water compliance, request the AS/NZS 4020 test statement with your order.

Why InstroDirect vs Endress+Hauser or HACH in Australia
InstroDirect supplies the same grade of water-quality sensor that Australian councils, WWTP integrators, pharma plants, and food & beverage operators specify from Endress+Hauser and HACH — at a significantly lower landed cost and without vendor lock-in.
| Factor | InstroDirect | Endress+Hauser / HACH |
|---|---|---|
| Digital protocol | Open RS485 Modbus RTU — integrates with Allen-Bradley, Siemens, Schneider, Beckhoff, or any SCADA | Proprietary (E+H Memosens / HACH SC digital) — locked to the vendor’s transmitter |
| Technical support | Australian field engineers with 20+ years automation experience | Remote support via offshore ticket queues |
| On-site calibration | InstroDirect technicians available across QLD, NSW, VIC with formal calibration certificate | Third-party authorised service network, longer turnaround |
| Price | Parallel-import model — no distributor margin stack, typically 30–50% below equivalent brand pricing | Premium brand pricing with tiered distributor markup |
| Replacement parts | Standard consumables ordered on demand from InstroDirect | Proprietary cartridges and cells, tied to the brand |
Moving away from Memosens or SC digital protocols frees you to mix and match sensors with any Modbus-capable transmitter or PLC. InstroDirect probes drop straight into an existing control system without a new proprietary transmitter.
