Pyxis ST-711SS Inline Stainless Steel ORP Analyser (Replaceable Electrode)

Model:
ST-711SS
Brand:
Pyxis

The Pyxis ST-711SS is an inline ORP analyser for continuous process and treatment water monitoring, covering a range up to +1,500mV. Its stainless steel body houses a replaceable electrode head, so the sensing element can be renewed without replacing the entire unit. Dual 4-20mA analog and RS-485 Modbus outputs via an 8-pin connector support direct integration into existing control systems.

Replaceable electrode — swap the sensing head without replacing the whole analyser, cutting maintenance costs
Dual output flexibility — 4-20mA analog and RS-485 Modbus outputs let it integrate with PLCs or SCADA systems
Replaceable electrode — swap the sensing head without replacing the whole analyser, cutting maintenance costs

Description

The Pyxis ST-711SS is an inline ORP (oxidation-reduction potential) analyser built for continuous monitoring of process and treatment water, with a measurement range up to +1,500mV. It gives operators a real-time view of the oxidizing or reducing conditions in a water stream, a key indicator for disinfection and chemical dosing control.

The analyser’s stainless steel body houses a replaceable electrode head, so the sensing element can be renewed without discarding the whole unit — reducing long-term maintenance costs in continuous-duty installations.

Dual 4-20mA analog and RS-485 Modbus outputs, delivered through an 8-pin connector, allow the ST-711SS to feed directly into existing controllers, PLCs, or SCADA systems for automated ORP-based control.

Why Use This

Reliable ORP Monitoring

Measures oxidation-reduction potential up to +1,500mV for process and treatment water control.

Lower Maintenance Cost

The replaceable electrode head means the sensing element can be renewed without replacing the whole analyser.

Flexible System Integration

Dual 4-20mA and RS-485 Modbus outputs support integration with existing control systems.

Applications

  • Disinfection monitoring — tracking ORP to verify oxidizing conditions during chlorination or ozonation
  • Process water treatment control — feeding ORP readings into automated dosing control loops
  • Industrial water quality verification — confirming redox conditions in treated process streams

FAQ

What does the ST-711SS measure?

It measures oxidation-reduction potential (ORP) in process and treatment water, up to a range of +1,500mV.

Is the electrode replaceable?

Yes, the sensing element is a replaceable electrode head, so it can be swapped without replacing the full stainless steel analyser.

What outputs does it provide for control integration?

It provides 4-20mA analog output and RS-485 Modbus, connected via an 8-pin connector, for integration with PLCs and SCADA systems.

What material is the analyser body?

Stainless steel, for durability in industrial water applications.
