CIP-Compatible Industrial pH Sensor — 110°C
The InstroDirect IDH-320T Industrial pH Sensor – CIP-Compatible, Extended Temperature is an industrial pH sensor rated for short-duration CIP / SIP exposure up to 110 °C with rapid recovery to normal process temperature. Designed for food & beverage, dairy, and brewery pipework where periodic caustic and acid clean-in-place cycles would destroy a standard electrode.

Typical Australian Applications
- Dairy CIP return
- Brewery wort pH
- Soft-drink bottling line sanitiser control
- Food ingredient water
- Cheese and yoghurt fermentation
Why Engineers Choose the IDH-320T
- Triple-junction reference survives repeated caustic CIP exposure
- EPDM O-rings for caustic-heavy CIP or FKM for acid-heavy (specify)
- 316L mirror-polished wetted parts for hygienic compatibility
- Quick thermal recovery after SIP cycles
Installation & Calibration
Install in CIP return line downstream of the heat exchanger. Calibrate monthly during production runs and re-validate after each full CIP cycle.
Frequently Asked Questions
Is this 3A compliant?
The 316L wetted parts meet 3A material standards. Full 3A certification documentation available on request for pharma and dairy customers.
Australian Technical Support & On-Site Calibration
- Australian field engineers with 20+ years of industrial automation experience — phone and email support during AEST business hours.
- On-site pH calibration service across QLD, NSW, VIC — two-point buffer calibration (pH 4 / 7 / 10) with formal calibration certificate.
- Sensor health diagnostics — slope, offset, glass impedance, and reference junction checks.
- Replacement electrodes and buffer solutions available from InstroDirect’s broader water-analysis range.
Why InstroDirect vs Endress+Hauser or HACH in Australia
InstroDirect supplies the same grade of pH sensor that Australian councils, WWTP integrators, pharma plants, and food & beverage operators specify from Endress+Hauser (CPS11D, CPS31D, CPS41D, CPS71D) and HACH (pHD, Differential pH) — 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 Memosens / HACH SC — locked to the vendor’s transmitter |
| Technical support | Australian field engineers with 20+ years automation experience | Offshore ticket queue or authorised distributor |
| On-site calibration | InstroDirect service across QLD, NSW, VIC with formal certificate | Third-party authorised service network, longer turnaround |
| Price | Parallel-import, no distributor margin stack — typically 30–50% below equivalent E+H / HACH pricing | Premium brand with distributor markup |
| Replacement parts | Standard glass-bulb and reference cartridges | Proprietary Memosens head, 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 pH electrodes drop straight into an existing control system without a new proprietary transmitter.
