Fits high-temperature and high-pressure pH/ORP where you need a Rosemount 3300HT or 3300HTVP PERpH-X sensor—pH 0–14, ORP −1500…+1500 mV, titanium body, rebuildable double-junction reference, and up to 155 °C / 400 psig class.
Key advantages
- Range — pH 0–14; ORP −1500…+1500 mV
- Temperature — 5–155 °C without preamp; to 100 °C with preamp
- Pressure — Max 400 psig
- Body — Titanium; PTFE junction; Pt-100
- Cable — Integral (HT) or VP8 (HTVP)
Typical applications
- High-temperature process pH.
- Retractable insertion assemblies.
- Poisoning / fouling resistant electrolyte options.
Selection guide
- HT vs HTVP connector
- Electrolyte option
- Process connector / length
Common mistakes
- Using without required 1 in compression connector.
- Exceeding preamp temperature limit.
- Wrong O-ring material for chemistry.
When to RFQ / what to tell us
- HT vs HTVP, electrolyte.
- Quantity, ship-to.
