Product details
Sanitary Tri-Clamp Conductivity Sensor — Pharma, Food & Beverage
The InstroDirect IDC-2W-SAN Sanitary Tri-Clamp 2-Electrode Conductivity Sensor is a hygienic-process conductivity probe with a 316L polished stainless tri-clamp flange designed for CIP / SIP service in pharmaceutical, dairy, brewing, and food & beverage plants. 3A-compliant wetted materials and FKM / EPDM O-ring options cover clean-in-place acid / caustic cycles and steam sanitisation to 135 °C.

Why Integrators Choose the IDC-2W-SAN
- 316L 0.5 Ra polished finish meets 3A sanitary standards
- Handles full CIP caustic (NaOH) and acid (HNO3 / phosphoric) cycles
- SIP-rated to 135 °C steam sanitisation
- Tri-clamp mount makes swap-out a 30-second job
- Wide 0–200 mS/cm range covers both pure water and caustic phases on the same probe
Installation & Calibration Notes
Install vertically in the CIP return line or horizontally with the electrodes fully flooded. Use EPDM O-rings for caustic-heavy CIP, FKM for acid-heavy or steam. Calibrate with KCl standards monthly during production runs; validate after every SIP cycle.
Frequently Asked Questions
Is this 3A compliant?
Yes — 316L with 0.5 Ra polish. The full 3A certification documentation ships with every order on request.
What tri-clamp size should I order?
Most AU dairy and brewery CIP lines use 1.5″ or 2″. Specify your line size at order; we stock both ready for next-day dispatch.
Does it handle caustic and acid CIP?
Yes. 316L polish with EPDM O-rings handles 2–5% NaOH and nitric / phosphoric acids at 80 °C. For stronger chemistries, ask about the PEEK-body alternative.

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.
