Key parameters
Measuring range
pH 0–14 (sensor versions); ORP ±1500 mV class (2725 flat ORP); general-purpose DryLoc electrodes
Accuracy
Electrode-dependent; calibrate with buffers per instruction manual
Output
Analog sensor signal via DryLoc connector to GF transmitters (e.g. 9900/9950) or preamplifiers
Supply
Passive electrode (powered/conditioned by transmitter)
Process connection
¾ in NPT or ISO 7/1-R ¾ threads
Wetted parts
Ryton / glass / PTFE / elastomer options per version; HF-resistant and low-conductivity pH options
Fits in-line pH/ORP sensing where you need GF Signet 2724–2726 DryLoc electrodes covering 0–14 pH or ±1500 mV ORP class with ¾ in process threads into 9900/9950 transmitters.
Key advantages
- pH — 0–14 (sensor versions)
- ORP — ±1500 mV class (2725 flat ORP)
- Connection — DryLoc connector to GF transmitters/preamps
- Process connection — ¾ in NPT or ISO 7/1-R ¾
- Wetted — Ryton / glass / PTFE / elastomer options per version
Typical applications
- Water treatment pH control.
- ORP monitoring in disinfection.
- GF 9900/9950 transmitter loops.
Selection guide
- pH vs ORP version — 2724/2726 vs 2725
- Flat vs bulb — Fouling duty
- Thread — NPT vs ISO
- Transmitter — 9900/9950 compatibility
Common mistakes
- Running without buffer calibration.
- Wrong chemical compatibility for Ryton/PTFE.
- DryLoc mismates to non-GF electronics.
When to RFQ / what to tell us
- pH vs ORP version, thread, cable/preamp.
- Quantity and ship-to.
